Vehicle Diagnosis, Testing and Information System
VAS 5051B
You can operate the VAS 5051B as a mobile unit in the workshop. When connected to a
vehicle via diagnostic and measurement cables, it provides electronic support for the
finding and localizing of faults.
Its main component is the tester. This remains integrated into the workshop trolley during
operation in the workshop, although it can also be operated separately, e.g. in a vehicle.
Results can be printed using a printer (customized installation of the printer is possible).
At the request of the customer, the VAS 5051B is delivered with a workshop trolley from
Fa. Knürr or Fa. Rawotec. Furthermore, it can also be used on a VAS 5051 workshop
trolley already owned by the operator. The operator must make the modifications
required to the VAS 5051 workshop trolley himself in accordance to the enclosed installation instructions and using the required mechanical components.
The tester is supplied with power either from a table power adapter integrated into the
workshop trolley, from the internal battery pack or from the vehicle's battery.

2.2
Tester VAS 5051B
The tester provides several different ➚ operating modes to choose from, such as Vehicle
Self-Diagnosis, Test Instruments, Guided Fault Finding and Guided Functions. It can
therefore be used equally well as a fault reader, a measuring instrument and an intelligent fault identification system.
The operating system and the applications are stored in the tester.
The tester reacts to entries that are made by touching the ➚ touch screen directly using a
finger or the touch pen integrated into the device. Alternatively, the tester can also be
operated using the enclosed USB mouse.
The printer of the workshop trolley is operated via the USB interface. When re-equipping
a VAS 5051 workshop trolley, the already existing IrDA interface is used. The user's own
printer (USB or LAN) can also be installed in the system. The printer is setup in the
Administration.

2.2.1
Power Supply
The tester can be operated with an AC current between 100 and 240 V via the table
power adapter integrated into the workshop trolley or from the vehicle's on-board electrical system via the diagnostic cable. The built-in battery pack supplies the device with
power for up to 60 minutes continuously (depending on the operating mode). This
ensures that the tester does not have to be switched off when changing location.
Note
It is possible to operate the tester with power from the on-board network using the diagnostic cable (without connecting the table power adapter) only when the vehicle battery
is sufficiently charged. Its power consumption is limited to approx. 45 watt. The remainder of the required energy is taken from the battery pack of the tester. When operated in
this way, the tester should therefore not be operated with an empty battery pack.
Caution!
Printer Connection
The voltage range of the printer is different from that of the tester and limited to a particular rated voltage. Make sure when connecting the printer that it is supplied with the
correct voltage.

Meaning of the LEDs
This flashes red if the tester is too hot.
If LED 3 begins to flash then the tester switches itself off automatically
after approx. 10 s. The LED keeps flashing. The fan is kept on to cool
down the tester.
If the overtemperature remains after the device has switched off then
the tester prevents itself from being switched back on until it has sufficiently cooled down.
When using the battery, the cooling-down process is limited to a maximum of 5 minutes and then the tester is turned off completely. If the
tester is switched back on while it is cooling down then the cooling-off
process is repeated again for a maximum of 5 minutes.
2.2.2.3
Touch Screen
The touch screen is the user interface. Masks with selection boxes and buttons appear on
this screen, and these should preferably be selected/pressed using the touch pen.
Energy saving mode
If the tester is not operated for several minutes then energy saving mode is switched on.
There are two energy saving modes depending on the power supply to the tester:
1. If the tester is supplied with power via the table power adapter or via the diagnostic
cable then the screen switches off after 15 minutes if it is not operated or if the programme that is currently running does not generate any continuous display on the
screen. As soon as you touch the screen near its upper edge, the last mask displayed
will be shown again. You should not touch other areas of the screen, since that could
trigger unintended programme functions. An exception to this is the Vehicle Self-Diagnosis operating mode which is ended with the blanking of the screen. The start mask
is then displayed after switching back on.
2. The screen blanks after 5 minutes when using the battery. Otherwise there are no differences here.

is to be measured. Cables can be adapted up to a diameter of 26 mm (100 A current
pick-up) or 32 mm (1800 A current pick-up).
The level of measurement accuracy depends to a large degree on being able to close
the two halves of the pick-up completely without there being any gap. To avoid measurement errors due, for example, to dirt within the root area, both pick-ups have a locking
control mechanism. The software thereby receives a signal that the two halves of the
pick-up are closed and that a measurement can now be made.
Furthermore, the 100 A pick-up is also equipped with a control LED in the grip (see
Fig. 2-19). If the pick-up is not correctly connected then the LED lights up. At the same
time, the following message appears in the information window to the right on the tester:
Current pick-up not closed!

Temperature sensor
The temperature sensor consists of a 10-pole pin plug (marked in green), the cable and
the sensor, which is made up of a hand grip and a 1 m long flexible protective tube made
of Teflon with an adjustable conical rubber seal.A PT100 element is located on the tip of
the dipstick. The rubber seal performs two important functions:
•
•
Determining the dipstick immersion depth
Hermetically sealing the measurement point
Fig. 2-23
Temperatur sensor (example)
Determining the immersion depth of the dipstick
The rubber sealing on the dipstick is set according to the instructions from the respective
function test (see /3/). This thereby limits the immersion depth of the dipstick, e.g. in the
oil sump. The immersion depth can differ depending on the vehicle.
Caution!
If the immersion depth is not set correctly using the rubber sealing, then the temperature sensor may be destroyed and the engine may be damaged.
Air-tight closing of the measurement point
The conical design of the rubber sealing allows the measurement point to be closed in an
air-tight manner.

Workshop Trolley
The workshop trolley is used for mobile use of the tester in the workshop. It is mounted
on four rollers to allow it to be easily pushed within the working environment.
Depending on the design of the system, one of the following is used:
Fa. Knürr workshop trolley
•
Fa. Rawotec workshop trolley
•
a re-equipped VAS 5051 workshop trolley (for operation, refer to /5/)
All workshop trolleys are equipped with a dust-protective cover. It can be folded together
during operation and stored in the storage compartment of the workshop trolley.
•
Note
When the VAS 5051B is not in use, the mains connector should be pulled and the dustprotective cover should always be pulled over the workshop trolley.
Mobility
Both front wheels of the workshop trolley have been equipped with brakes to allow it to
be fixed at its location.
Release the brakes to move the trolley. You can push or pull the trolley to its new location
using the grips on the front and rear. You can then lock the brakes at the new location.
You can change your work location when the tester is switched on as long as there is
sufficient charge remaining in the battery. Disconnect the mains cable from the mains
and re-establish the power supply at the new workplace.
You can also disconnect the tester from the table power adapter when switched on in
order, e.g. to take the tester into the vehicle. Open the lock at the handle and remove the
tester from the tester mount. As soon as the tester is connected via the diagnostic cable
to an vehicles’ on-board electrical system with sufficient power, it will be supplied with
power from the vehicle's battery. Observe LED 1. It changes to green or yellow when
power is supplied from the vehicle.

Ergonomics
There is a hinged cable arm to allow you to put down the diagnostic and measurement
cables ergonomically. Additionally, there is a holding fixture for looped cable to the rear of
the Knürr workshop trolley.
You can change the angle of inclination of the tester and its mount on the workshop
trolley from Fa. Rawotec and on the re-equipped VAS 5051 workshop trolley. This allows
you to adjust them ergonomically to the various working positions.
To change the angle of inclination at the Fa. Rawotec workshop trolley:
1. Grip the tester mount from below at the front and pull it up. You can clearly hear when
the mount snaps into its various positions.
2. After you have set the required angle, you must replace the keyboard mount into its
horizontal position. To do this, pull on the lock on the right side of the tester mount.
If you place the tester mount into its highest position then the locking mechanism releases
and the mount can once more be placed in its vertical position.
How to change the angle of inclination at the re-equipped VAS 5051 workshop trolley:
1. Grip the tester from above and below and swing it along the horizontal axis.
3.2.1
Using the tester without a workshop trolley
The tester has been designed for preferred use with the delivered workshop trolley. If the
tester is required during test drives then please observe the following:
Warning!
During test drives, secure the tester with a strap on the vehicle's back seat and connect
it to the vehicle using the diagnostic cable. A second person must operate the tester
from the back seat. Operation from the front seat is too dangerous, e.g. in the event of
airbag activation.

4.3.3
Test instruments
The test instruments are comprised of the test instrument board and the connected
measurement cables. However, the self-test in the tester that can be called up for the
test instruments does not include the measurement cables. This must be checked by
means of comparative measurement if necessary.
Before starting to test the measurement cables, you should carry out a self-test on the
test instrument unit in order to exclude that it is faulty. See /3/.
The test instruments can also display messages regarding measurement faults
independently. The following table shows an example:
Table 4-3
Fault report of the test Instruments
Symptom
When measuring the
resistance and the
continuity, the following
error message appears:
Measurement error:
external power supply.
4.3.3.1
Possible causes
The component to be
tested is live.
Remedy
Switch off the external power
supply.
Test instrument unit
The test instrument unit is tested by the self-test that is built into the tester. In case of an
error, a fault number appears in the work window: If "OK" is shown in the window then
the test instrument unit is OK.
If the test instrument unit produces a fault report then you should make a screenshot for
later proof.
4.3.3.2
Measurement cables
U/R/D/I measurement cable
A function test of the U/R/D/I measurement cable is carried out as follows. If the test
results do not match the required values then there is a fault in the corresponding
U/R/D/I measurement cable. In this case, please submit a fault report in accordance to
Section 4.4.

Troubleshooting
VAS 5051B
The U/R/D/I measurement cable is best checked using a comparative measurement.
Check the "voltage measurement" function, e.g. by connecting the leads to a vehicle
battery.
In the "resistance measurement" function, simulate an "open circuit" (Display: +++++ MΩ)
and "short-circuit" (near the display of 0.000 kΩ). You can also measure known resistances, e. g. of a relay coil (normally approx. 90 Ω).
When checking the diodes, you can also simulate an "open circuit" and "short-circuit".
However, a diode is required for additional tests. Check whether the appropriate symbols
(see /3/, Chapter Test Instruments) are displayed.
To check the "➚ inline current measurement" function you must use a circuit of max. 2 A.
DSO measurement cables
Carry out a function test of the DSO measurement cables as follows. If the test results do
not match the required values then there is a fault in the corresponding DSO
measurement cable. In this case, please submit a fault report in accordance to
Section 4.4.
1. Connect a DSO measurement cable to the DSO1 socket.
2. Press the Voltage DSO1 button in Test Instruments operating mode, Multimeter
mask. Select DC voltage as the type of measurement and the automatic range
selection.
3. Connect the measuring tips of the DSO measuring cable with a charged car battery..
The measurement value that is displayed must be the same as the battery voltage
(between 11 and 14 V).
4. Check the freeze image selection by pressing the button on the red/black probe tip.
The measurement value is frozen, the "freeze frame" button must appear to be
pressed on the screen.
Carry out a comparative measurement between U/R/D/I and DSO:
1. Release the freeze frame by pressing the button again in order to continue the
measurement.
2. Additionally connect the U/R/D/I measurement cable to the tester and the vehicle
battery. Its correct functioning should have been checked before connecting it.
3. Press the Voltage U/R/D button. Select DC voltage as the type of measurement and
the automatic range selection.
4. In both displayed measurement functions (DSO1 and U/R/D), the difference in the
measured values must be ≤ 0.2 V.

Troubleshooting
VAS 5051B
Repeat the function test with the second DSO measurement cable.
Note
Both DSO measurement cables are identical and can be exchanged for testing.
Current pick-ups
Carry out a function test of the current pick-ups as follows. If the test results do not match
the required values then there is a fault in the current pick-up. In this case, please submit
a fault report in accordance to Section 4.4.
1. Connect a current pick-up to the tester.
2. Press the Current pick-up button in Test Instruments, mask Multimeter. The current
pick-up must be automatically recognized. Select DC current as the type of
measurement and the automatic range selection.
3. Open and close the current pick-up several times without connecting it to a live cable.
The value measured must change considerably between these two states (open and
closed). In case of the 100 A pick-up, check whether the LED at the current pick-up
correctly displays the conditions "opened (LED is on) / closed (LED is off)".
Now check the calibration of the current pick-up:
1. Press the Calibrate button on the screen. Close the message displayed by pressing
the OK button. At most, the measured value displayed after calibration must equal the
tolerance in the lowest measurement range (see Section 6.3.1).
2. Connect the current pick-up to a battery cable or another cable of a consumer in a
vehicle. All consumers and the ignition of the vehicle should be switched off at first.
The displayed measurement result should only change marginally (environmental
influences).
How to perform a comparative measurement:
1. Switch on a consumer, e.g. the parking light. The power consumption should be
known as accurately as possible. Take this value as a starting point. The measured
value should be the same as this value.
2. Pull the current pick-up from the cable carrying the current and plug it back in,
reversed by 180°. The difference must remain within the stipulated tolerance (see
Section 6.3.1).

Trigger clamp and kV pick-up
The trigger clamp and kV pick-up can only be tested together. Carry out a function test
as follows. If the test results do not match the required values then there is a fault in one
of the sensors. In this case, please submit a fault report in accordance with Section 4.4.
1. Connect the trigger clamp and the kV pick-up to the tester.
2. Call up the DSO mask in operating mode Test Instruments, (see /3/).
3. Connect both pick-ups via the same ignition cable (secondary side of the ignition coil)
to a vehicle with a 4 or 6 cylinder engine.
4. Press the Preset measurement button in the DSO mask, select the Secondary ignition
voltage curve in the selection list that appears, and confirm with the Display button.
The DSO mask will appear with the set curve in the background. At the same time, all
DSO settings will be made automatically.
5. Start the vehicle's engine. The typical ignition signal must be displayed dynamically,
i.e. the picture is re-written once or twice per second if the kV pick-up and trigger
clamp are working correctly.
If the trigger clamp is faulty then the following message appears in the window at the top
right:
No trigger
If the kV pick-up is faulty then a horizontal line may only be displayed or else a signal
curve with much too small an amplitude.
Note
Depending on the type of vehicle used, the amplitude of the ignition signal may
fluctuate between 4 and 40 kV. The combustion voltage is normally between 600 and
1200 V, and the combustion duration should be between 1 and 6 ms. The shape of the
curve may vary depending on the manufacturer of the ignition coil.

Care and Maintenance
5.1
Optical check of the VAS 5051B
Carry out a regular optical check of the VAS 5051B. Examine all parts for damage
(e.g. breaks) and for dirt.
Check the touch screen for damage or dirt.
Regularly check the device, all cables and the accessories for damage.
Warning!
If the mains cable, a diagnostic or measurement cable, the tester or any accessory carrying live current is damaged, you must not use it until a properly qualified specialist has
investigated it and approved it.
5.2
Tester
If the housing is dirty then clean it with a lint-free, damp (not wet!) cloth.
Caution!
Before cleaning the tester, turn it off to ensure safety and pull out the DC supply plug.
Remove all measurement cables. Pay careful attention that no liquid enters into the
housing. Do not try to clean the insides of the DVD and disk drives.
Caution!
Do not overtighten the screws on the housing.
The housing of the tester is made of magnesium. Housing screws must therefore not be
screwed in too tightly (just as with aluminium). The build in screw theads may loosen
too. Take special care at the corner pieces.
Make sure that the venting slots to the left and right of the tester remain uncovered.
remove any dirt using a vacuum cleaner.
If the tester is damaged then please contact the SIEMENS hotline (see /4/).

VAS 5051B
5.2.1
Cleaning the touch screen
The most sensitive part of the tester is the touch screen. Its sensitivity to touch may be
impaired by dirt and by scratches. If it becomes dirty then clean it using a soft, non-lint
cloth. If the dirt can not be removed using the cloth then you can use isopropanol or an
ammonia-free glass cleaner.
5.2.2
Battery
The battery has a standard lifetime of approx. 500 charge/discharge cycles. It then has a
remaining capacity of approx. 50%.
Note
•
•
A lithium ion battery does not require formation.
The battery must be disposed of or recycled when completely discharged in accordance with the local regulations.
Caution!

Care and Maintenance
VAS 5051B
Battery maintenance
Due to age, the usable capacity of the battery decreases and the amount of faults
increases when measuring the capacity for the charging circuit. To compensate for this
process, a calibration must be carried out from time to time for the battery control. The
required maintenance interval is automatically reported by the tester and serves the purpose of optimizing the usable capacity of the battery. Follow the instructions on the screen
(see /3/).
5.2.3
Replacing the battery
Caution!
Always replace a defective battery with a new battery. Never operate the device without
a battery as the installed operating system may be destroyed if the power supply is
interrupted.
You can find the order number and source of supply for the expendable part in the Parts
List for the VAS 5051B.
Replace the battery as follows:
1. Place the tester with the screen downwards on an even, clean surface.
2. Remove the four screws on the cover of the battery pack (see Fig. 2-7, 10). To do this,
use a T10 TORX screwdriver.
3. Flap up the support leg.

Explanation
Unlearning
counter
Should an error occur during a driving cycle (terminal 15 on until
terminal 15 off) it is first entered as "static" in the fault memory. If it
is not detected during the next driving cycle, the designation is
changed to "sporadic" and an unlearning counter with an output
value of, for example, 40 is decremented by 1. This is repeated
during each driving cycle free of the fault, until the unlearning
counter reaches 0 and the fault is thus automatically cleared. However, if the registered fault should reoccur during a later driving
cycle, then the unlearning cycle is set to its output value and the
error provisionally set back to "static" again.
Update
Software modification package for updating an existing program to
a later version.
1. New version of the ➚run-time system which is downloaded from
➚CD.
2. New program version of a ➚vehicle system which is imported by
the tester.
URL
Abbreviation of "Uniform Resource Locator". A URL corresponds to
the address of an internet resource (web site, file, etc.).
Example: www.siemens.com
USB
Universal Serial Bus. USB is a standardized interface for connecting, for example, keyboard, ➚USB memory.
USB storage
device
Also known as USB memory stick. A mobile, easy to handle memory unit with a USB interface. It is plugged into the USB port on the
tester and is detected automatically by the tester. Assignment
takes place with the function "Set output medium on removable
storage device" (navigation bar, print). Now you can send, for
example, logs or screen shots to the USB memory.
User test plan
➚Diagnostic strategy based on the selection of descriptions of possible defective functions and components by the user. If faults in
the vehicle system are detected during diagnosis or a complaint
report is entered, the test plan differentiates between the system
test plan and a user test plan.

Explanation
Variant,
variant rule
This term is used with reference to the ➚vehicle system fittings.
Some fittings, for example an airbag, may be available in various
variants for an identified vehicle. The most important task of the
vehicle system test is to find out which variant is actually installed.
If the variants cannot be determined automatically, Yes/No
questions on the fitting will follow, e.g. "Automatic gearbox?".
The mechanisms used to determine the variants are known as
variant rules. Their results determine which diagnosis data should
be made available, amongst other things.
Vehicle identification
Vehicle identification is defined by the vehicle's ➚basic feature
components (type, model year, body version, engine code) that can
be determined automatically or partly automatically in an existing
gateway. These data are used to check a list of all possibly
installed electronic control units/devices and their installation in the
➚vehicle system test.
Vehicle SelfDiagnosis
VAS 505x operating mode in which you can communicate with the
➚vehicle systems available in the vehicle and carry out a thorough
➚diagnosis, via dialog boxes.
Vehicle system
A ➚control unit of a known name, e.g. motor control unit, including
the appropriate ➚sensors, actuators and wiring.
Vehicle system
test
A list of all possibly installed vehicle systems (electronic control
units, devices) is generated from the ➚vehicle identification. In the
vehicle system test, all systems are examined for availability and
their error status is queried. If necessary, inquiries about equipment
appear here also.
Virtual keyboard
The graphic representation of a keyboard on a ➚screen. The individual buttons can be operated by touching them with a touch pen
in the same way as those of a real keyboard.
Work window
The work window takes up the largest part of the ➚mask.
The display changes according to the ➚operating mode and current progress. Here you can make a selection, or view results
(e.g. from ➚Test Instruments).
