Introduction
ECOM (Engine Communication) is a program which, together with the VCI (Vehicle
Communication Interface) and USB key (Universal Serial Bus), enables communication
between your PC and the control unit (EMS S6) on the engine.
You can carry out the following operations with ECOM:
•
Read stored fault codes and ‘Freeze Frames’. You can find out more about ‘Freeze
Frames’ on page 10 point 6.
•
Clear inactive fault codes
•
Read information about stored working cycles
•
Measure internal variables such as the engine speed, pressure, temperature and
save them to a file
•
Program certain parameters
The user manual is structured as follows.
On pages 5 - 7 you will find an overview of the user interface with section numbers and
page references. If you only wish to read one specific section, you just turn to the page
indicated.
Certain functions in ECOM require real-time via CAN. The control unit (EMS S6) is not
equipped with a real-time clock.
Lists of the variables and parameters which are available in ECOM are provided at the
end of this manual.

Connection to CAN (Controller Area Network)
It is necessary to connect power (+24V) and CAN (high and low) to the VCI in order to use
ECOM. This can be done in two different ways depending on whether you are using the
Scania electrical system or your own. The illustration below shows the different
connection options.

1. By pressing the ‘Read’ button, ECOM downloads all the stored fault codes from the
fault code memory into the control unit. They are displayed in the field below (see
point 4). ‘Erase’ is pressed to clear all inactive fault codes. Note that this only erases
inactive fault codes. Active fault codes must be rectified before they can be erased.
2. If you click ‘Save’, ECOM will write all the current fault codes and all Freeze Frames
(see point 6) to a text file. When ECOM has finished doing this, the program will ask
where you wish to save the file (see illustration below). This function can be useful if
you need to send information to a service engineer.

3. Press the ‘Load Info’ button to upload general information from the control unit to
ECOM.
4. The fault codes which are stored in the control unit are displayed in the field
‘Diagnostic Faultcodes’. The columns in the field are grouped as follows: DTC
(Diagnostic Trouble Codes), Counter (Number of times the fault has occurred), Status
(Active or passive), Date and time (requires real-time via CAN), Description of the fault
code. By clicking on one of the fault codes a detailed description will be displayed in
the field at the bottom (see point 5).
5. This field provides a detailed presentation of the fault code selected in the field above.
It also shows how the system reacts to the fault and provides a brief troubleshooting
procedure.
6. If the option ‘Show Freeze Frame’ is selected, ECOM displays a ‘Freeze Frame’ for
the selected fault code. A Freeze Frame is generated by the control unit at the moment
a fault code occurs for the first time and it contains approximately 65 different variables
and their values. This can be extremely useful for the service engineer who has to
understand and resolve the problem. By clicking the ‘Export’ button, it is possible to
save the displayed Freeze Frame as a text file. The file can then be opened, preferably
in MS Excel.

In the text below, references are made to points in the illustration above. For example:
Click the button ‘Show all variables’ (see point 1). You will find usable measurement
variables and examples on pages 43 and 44 respectively.
A. The first thing to do when measuring variables is to retrieve these from the control unit.
This is done by clicking on the button ‘Show all variables’ (see point 1). When the
variables have finished loading, they are displayed in the field ‘All list names /
descriptions’ (see point 2).
It is possible to display the variables according to their description or their variable
name. This selection can be made in the ‘ViewMode’ field (see point 3).
In addition, it is possible to make a selection from the variables list by searching on
text. Enter the text you wish to search on, e.g.: pressure, beside the ‘Search’ button
and then click the button (see point 4). The variables containing the text you have
searched on are displayed in the field above (see point 2).
© 2006 Scania Industrial & Marine Engines
12
B. The next step is to select the variables to be measured. Highlight the variable you wish
to measure and then click the right arrow (see point 5). The variable then moves to the
‘Selected to view by list’ field (see point 6). The variables that you choose to place here
are displayed with their respective values under the ‘View List’ tab (see point 7) when
you start the measurement (see section F). You can place a maximum of 35 variables
in this list.
C. If you wish to see a graph of the variables you have selected, transfer them to the
‘Selected to view by plot’ field (see point 8) by clicking on the right arrow to the right of
the ‘Selected to view by list’ field (see point 9). You can place a maximum of 4
variables in this list. Note that you cannot move variables directly to this field. The
variables that you choose to place here are displayed graphically under the
‘Oscilloscope’ tab (see point 10) when you start the measurement (see section F).
Before you start the measurement, you can choose whether to have an automatically
adjusted or manually fixed scale. This is done at the bottom of the window. When the
measurement has stopped, a marker can be moved along the curve to see the current
value after a certain time in seconds. The marker is moved by holding the left mouse
button down at the same time as dragging the mouse along the curve. The value is
displayed in the list below.
© 2006 Scania Industrial & Marine Engines
13
D. It is also possible, if required, to see a plot of the variables placed in the ‘Selected to
view by XY-Plot’ field (see point 14). The variables are moved by clicking the right
arrow at the bottom right of the ‘Selected to view by list’ field (see point 15). You can
place a maximum of 2 variables in this list. These will be displayed graphically in
correlation to each other under the ‘XY-Plot’ tab (see point 16). The variables are
displayed on the X or Y axis, depending on what you select. You change the variable
axis by clicking on the arrow beside the ‘Selected to view by XY-Plot’ field (see
point 17). The axes can have an automatically adjusted or manually fixed scale. Note
that you cannot move variables directly to this field.
E. If you frequently measure the same variables, after making your selection as above,
you can save this selection by clicking the ‘Save’ button in the ‘Predefined selections’
field (see point 11). Enter a name for your list and click ‘OK’. When you wish to retrieve
a saved list, first select the list you require in the menu and then click the ‘Load’ button.
F. To start measuring the variables you have selected, click the ‘Start’ button in the
‘Logging’ field (see point 12). You can now go to the relevant tab for list or graph to
see the current values. When you have finished measuring, click the ‘Stop’ button. If
you decided to use the ‘XY-Plot’ function, you will be asked whether you wish to save
the result as an image file. You can also save your measurements to a text file, only
measure within defined ranges of the values of variables or measure when a fault code
occurs. This is described in sections G and H.
© 2006 Scania Industrial & Marine Engines
14
G. To save your measurements to a text file, select ‘All’ in the ‘Logging’ field (see
point 12). If you wish to have the option to copy the contents in the text file to the
program Microsoft Excel you should also select ‘Excel portable’ in the same field.
When you start the measurement, you must indicate where you wish to save the file
and state its name.
If the program is only required to record when the value of the variable is within a
defined range, you should proceed as follows. Select ‘SRC Trig’ in the ‘Logging’ field
(see point 12). Highlight the variable for which you wish to indicate the range in the
‘Selected to view by list’ or ‘Selected to view by plot’ field (see points 6 and 8). Then
indicate the limits (Min - Max) you require in the ‘Triggers’ field (see point 13). Now the
program will only save the values which are within these limits to the text file.
You can also see when a variable is within the specified range under the ‘View List’
tab (see point 7), where it is highlighted by a solid circle. If the variable is outside the
specified range, the circle is empty.

15
H. Another function which can be used is ‘Diagnostic Trouble Codes’ (see point 18).
ECOM can be used here to start measuring when a fault code is generated in the
control unit. The function is activated by selecting ‘Enable DTC’. To save your
measurement to a text file, select ‘DTC Trig’ in the ‘Logging’ field (see point 12).
It is possible to arrange for the measurement to start when a fault code of any kind is
generated by selecting ‘Trig on any new DTC’. If, however, you wish to specify one or
more specific fault codes, enter these beside the ‘Add’ button and then click ‘Add’. The
fault code will then appear in the large field above. You can also set the point at which
ECOM should start measuring before a fault code is generated. This is done by
entering the number of seconds in the ‘pre-trig time’ field. Similarly, you can also set
the length of time which should be measured after a code has been generated in the
‘post-trig time’ field (0=infinite).
If you select this function the fault code status will be displayed in the ‘DTC Status’ field
(see point 19). If a fault code is active, this symbol is displayed before the fault
code,
. Information about the fault codes can also be obtained under the ‘View
DTC’ tab (see point 20).

2.4 Data logs
2.4.1 Generic map
1
2
This option displays the generic maps (map 1, 2, 3, 4) which the control unit stores.
‘Map 1’ is the only map providing information which is applicable to Scania industrial and
marine engines (oil pressure as a function of the engine speed).
1. In this field you can select which maps you wish to use. When you have made your
selection, press the appropriate button (‘Read’, ‘Reset’ or ‘Save’). ‘Read’ loads data
from the control unit and displays it in the field below (see section 2). ‘Reset’ resets the
map which is selected and ‘Save’ saves the highlighted selections to a text file.

Information about how the engine has been used can be read here in three different ways.
Each second information is stored about the engine working cycle and it can be displayed
as a map of the working cycle, as vectors of the variable values and as min/max values.
In the text below, references are made to points in the illustration above. For example:
Click the button ‘Read LT’ (see point 1).
A. You can use the buttons in the ‘Maps’ field to view maps of the engine working cycle
(see point 1). Information can be obtained from a long-term map or a resettable
short-term map. The long-term map contains information from the point at which the
engine was started for the first time. Both are displayed as a biaxial matrix with engine
speed on one axis, and load in percent on the other.
The ‘Read LT’ button displays the long-term map and the ‘Read ST’ button displays
the short-term map. They are displayed in the field below (see point 2). The other
buttons are used as follows: ‘Reset ST’ resets the short-term map, ‘TimeStamp ST’
can be used to view when the latest map was reset (requires real-time via CAN),
‘Distance ST’ applies only to trucks. Information can also be displayed graphically
under the ‘Color diagram’ tab (see section F).
© 2006 Scania Industrial & Marine Engines
20
B. Information for vectors of variable values is controlled in the ‘Vectors’ field (see
point 3). 32 variable values are stored in the control unit, as both long-term and
short-term values. The long-term values are stored from the point at which the engine
was started for the first time, whereas the short-term values can be reset.
Click the ‘Read LT + ST’ button to display the information in the field below (see
point 2). The information is displayed as the number of seconds for which the value
has been between two breakpoints.
Short-term values can be reset in two different ways. Each value can be reset
individually by selecting the number of the value and then pressing the ‘Reset ST
individual’ button. If you wish to reset all the values, press the ‘Reset all ST’ button.
Other buttons are as follows: ‘Distance ST’ applies only to trucks, ‘TimeStamp ST’ can
be used to view when the short-term values were last reset (requires real-time via
CAN), ‘Read update frequency’ is used to view the updating frequency for the control
unit.
© 2006 Scania Industrial & Marine Engines
21
C. Minimum and maximum information is controlled in the ‘Min/Max’ field (see point 4).
The minimum and maximum values for 32 variables are stored in the control unit and
displayed by clicking the ‘Read’ button. The values can be reset by clicking the ‘Reset’
button. The other buttons are used as follows: ‘Distance’ applies only to trucks,
‘TimeStamp’ can be used to view when the minimum and maximum values were last
reset (requires real-time via CAN).
D. ‘Engine speed buffer’ (see point 5) is a function for engine speed statistics. This
information can be useful when contacting a service engineer.
E. There are a number of buttons in the ‘Save data to file’ field (see point 6) which can
be used to save information to a text file. Press the button for the save process you
wish to carry out.
© 2006 Scania Industrial & Marine Engines
22
F. In the ‘Color map’ field (see point 7), it is possible to change the number of colours
which depict the values displayed graphically by clicking the ‘+’ and ‘-’ buttons. The
values are displayed graphically as a percentage of the total time under the ‘Color
diagram’ tab. The more colours that are used, the shorter the interval that can be read
in the graphic display.

The parameters in the control unit which are available to the aftermarket can be
reprogrammed here. A list of the parameters can be found on page 45.
1. By pressing the ‘Read values’ button, the parameters which can be amended in the
control unit are loaded. They are displayed in the ‘Common IDs’ field below (see
point 3).
When you have finished making changes, click the ‘Write values’ button. ECOM then
writes the new values to the control unit. After completing the programming, an
information box displays what has been programmed.
© 2006 Scania Industrial & Marine Engines
24
The ‘Save values’ button saves all the parameters and their values to a text file.
‘Bitmask Info’ is a help function which contains information about different values and
their significance for certain parameters (see illustration below). You can also find
information about the meaning of the values under ‘Alarm / Error reactions’ on
page 46.
2. In the ‘Order by’ field, it is possible to sort the parameters which are displayed in the
‘Common IDs’ field in alphabetical order in three different ways. According to Common
ID, parameter description or parameter name.
3. Parameters which can be changed on the aftermarket are displayed in the ‘Common
IDs’ field. They are described in columns as follows. Description (description of the
parameter in plain text), E2 parameter name (parameter name in the software), Value
(current value), Default value (value loaded into the control unit memory if there is a
fault), Unit (unit in which the parameter is measured), Common ID (hexadecimal ID
number).
If you wish to change a value in the control unit, enter it in the Value column and then
click the ‘Write values’ button (see point 1).

This function handles the programming of parameters consisting of several parts. It may,
for example, be a torque curve in which each part which can be programmed corresponds
to a specific engine speed. For information about what can be programmed, please refer
to the Parameters (Arrays) list on page 48.
1. By pressing the ‘Read values’ button, the Common IDs which can be amended in the
control unit are loaded. They are displayed in the ‘Common ID’ field below (see
point 2).
When you have finished making changes, click the ‘Write values’ button. First an
information box will display which Common ID has been programmed and its values.
ECOM then writes the new values to the control unit. After completing the
programming, an information box displays whether the programming was successful.
The ‘Save values’ button saves all the parameters and their values to a text file.
© 2006 Scania Industrial & Marine Engines
26
2. Two different Common IDs can be programmed at the same time and there are
therefore two fields for them here. It may sometimes be necessary to view one
Common ID in order to determine what should be programmed into the other one.
Select Common ID in the list and then click the ‘Show’ button to display the current
values in the ‘E2 Value’ line. You can see the parts (bytes) which the Common ID
consists of in the bottom line. The middle ‘Default Value’ line describes the base
values, if applicable, for each part. At the right-hand edge of the field you can see the
unit in which the Common ID you have selected is described.
You can change the values in the top ‘E2 Value’ line and then click the ‘Write values’
button (see point 1).

2.6 Engine test
2.6.1 Falldown Test

IMPORTANT! This test should only be carried out along with a Scania service engineer.
The aim of this test is to assess the condition of each cylinder in the engine. The engine
must be synchronised before the test begins, which means that the engine must be idling
when the test begins. Preferably, the engine should also has reached an temperature of
75-85 oC.
The test is carried out by first revving up the engine to a given speed. When the engine
speed has been reached, the fuel supply is shut off to all cylinders apart from the cylinder
whose condition is to be tested. A specified amount of fuel is supplied to this cylinder.
© 2006 Scania Industrial & Marine Engines
28
The engine speed will fall because the engine power has been reduced substantially. The
rate of engine speed retardation reflects the output of the engine (in other words, the
output from the single cylinder receiving fuel). The retardation is measured by measuring
the time it takes the engine to fall between two specified engine speeds (see illustration
below).
This procedure is repeated a number of times for each cylinder in the engine. This
provides an average falldown time value for each cylinder, a value which can be used to
compare the different cylinders. A well-functioning engine should have the same falldown
time for all cylinders. Note that a variation of +/- 3% is not abnormal for this test.
1. Click the ‘Start’ button to start the test.
2. When you start the test, the parameters in the ‘Init data’ field are transmitted to the
control unit. The control unit then carries out the test in accordance with these
parameters.
3. Information about the status of the current test is displayed here.
4. Click the ‘ChkStat’ button after completing the test to display the test status (see
point 3).

IMPORTANT! This test should only be carried out along with a Scania service engineer.
IMPORTANT! This test can only be carried out if the starter motor is controlled via the
control unit.
IMPORTANT! You must consult the conversion table on page 31 to read out the correct
result of the test.
The test can be used to see if any cylinder deviates from the other cylinders in the engine.
If possible, the test should be carried out when the engine has a normal working
temperature.
The engine must be synchronised before the test begins, which means that the engine
must be idling when the test begins. When the above conditions are fulfilled, the engine
will be stopped. The starter motor will then crank the engine for a given number of
revolutions and at the same time measure the average angular speed within a specific
angular range before and after top dead centre (TDC). The torque load on the starter
motor will vary according to the compression in each cylinder, and thus the angular speed
on the crankshaft will also vary.
The result is displayed as times for each cylinder. The times can then be compared with
one another to see if any cylinder deviates from the others. Note that a variation of +/- 2%
is not abnormal for this test.

IMPORTANT! This test should only be carried out along with a Scania service engineer.
IMPORTANT! This test is only valid for single speed engines and works only in software
version 2270 or later.
The aim of this step response test is to tune the engine speed regulator using the result
of this test in the Engine Control Unit parameters. It’s useful if none of the three factory
presets (normal/soft/stiff) are suitable for a specific installation.
For the test to be carried out successfully there is some conditions that has to be fulfilled:
- No active fault codes
- Unloaded engine
- Normal oil pressure
- Normal working temperature
- The engine has been synchronized at start
If any of these conditions is unfulfilled during the test, the test will be cancelled.
Also, the Common ID FE69 (overspeed protection) should be changed to 40% to avoid
conflicts in RPM during the test. Don’t forget to change this back after testing is finished.
The test is carried out by first revving up the engine to a given speed. When the engine
speed is stable, a small rise in the fuel amount is made. The engine speed rises slowly
and stabilizes at a new, higher, level.
This procedure is repeated three times. Data from the test is then used to calculate two
new sets of regulator parameters which can be selected in the Common ID FCFD (see
page 46).

1. Click the ‘Start’ button to start the test. The ‘Stop’ button is used to cancel the test. The
test will also be cancelled if the ignition key is turned off.
2. When you start the test, the parameters in the ‘Init data’ field are transmitted to the
control unit. The control unit then carries out the test in accordance with these
parameters.
3. Information about the status of the current test is displayed here.
4. Click the ‘ChkStat’ button to display the test status (see point 3).
5. When the test is finished, click the ‘Read result’ button. The test result is shown in the
‘Result Engine Test’ field (see point 6). Also, two sets of parameters are calculated
and can be used by setting the Common ID FCFD to value 10 or 11 (10=first set,
11=second set).

Examples
Two examples are provided below of troubleshooting that can be carried out if the engine
performance is poor. Both are taken from actual cases.
Troubleshooting – internal synchronisation problem
On earlier engines with PDE injectors and EMS, sometimes the control unit cannot
determine which cylinder it should inject fuel into. The engine therefore does not reach full
power since the problem causes a torque reduction until the engine is synchronised.
To determine whether this may be the problem, ECOM is used to measure the variable
‘Engine speed, if phase is checked or not’ (Eess_s_EpsPhaseLocked_S08r). The
variable displays the value 0 as long as the engine is not synchronised. When the engine
is synchronised, the value 1 is displayed.
This problem has now been resolved and should therefore not occur on new engines.
Troubleshooting – regulator (applies only to DC16A)
If there are problems with the power on an engine, it can be useful to see which regulator
determines the fuel quantity and how much fuel is used at present. Use the measurement
variables below to check this.
