Preface
The program cassette in the Multi-Tester pro is the component which
gives the diagnostic equipment its unique test performance. The program
cassette can easily be changed to set the Multi-Tester pro up quickly for
the diagnostic task at hand.
The Multi-Tester pro software is available in two levels of functionality,
Plus line and Pro line. This manual covers the operation of the Pro line
cartridge. Although operation and display screens are identical for each
line, please be aware that some of the functions described are not available
on Plus line cartridges.
The Plus line cartridge has the following functions: engine DTC:s and
monitor list, airbag DTC:s, ABS DTC:s and service light resetting as well
as snapshots.
This fault-finding instruction describes the serial application for trouble
shooting via the diagnostic connector on Opel and Vauxhall.

Programming
This function is only available on Immobiliser, Central locking, and Antitheft warning ECUs. It allows the transponder keys and remote-key fobs
to be erased and/or programmed for the vehicle.
For Immobiliser systems, transponder keys can be programmed into the
Immobiliser memory so that they may start the vehicle. For Central
locking or Anti-theft warning systems, the remote-key fob can be
programmed into the ECU so that it may be used to remotely operate
the door locks.
For Immobilisers and Anti-theft warning systems a four-digit pass code
must be entered before programming is allowed by the ECU. On entering
the programming menu, you will be asked for the four-digit pass code for the
car. This code can be found on the car pass supplied with the vehicle, and
is used to prevent unauthorised access to the key programming functions.
If the car pass is not available, the code can be obtained from a main dealer.
The vehicle registration details will be required.
Enter 4 digit vehicle pass code
0000
If an incorrect code is entered, you will be prompted to try again. It is
important to enter the pass code carefully as the ECU will activate it’s
security wait timer if an invalid pass code is entered. In this mode, it will
be impossible to erase or program keys until the security wait time has
expired.
Once the correct pass code is entered, the programming menu will be
displayed. For Immobiliser systems the following options are available.

Erase transponder keys
This function will erase all programmed transponder keys from the
Immobiliser memory. After this function has been used, none of the
vehicle’s keys will start the engine until they are re-programmed into
the Immobiliser. If a key has been lost / stolen, it is recommended to
erase all keys before programming the new keys, to ensure that the
Immobiliser will only recognise the keys held by the vehicle owner.
Program transponder key
This function will program a new transponder key into the Immobiliser
memory so that the key will be able to start the engine. You will be
prompted to insert the key to be programmed into the ignition. Then
follow the on-screen instructions to program the new key.
When communications have been established, you will be required to
enter your authorisation code before being allowed to program keys.
Your authorisation code is supplied to you by Autodiagnos when you
register the application. See the section on Multi-Tester pro registration
later in this manual for more details.
After entering the authorisation code, the following menu will be
displayed.

locks until they are re-programmed.
If a remote key has been lost / stolen, it is recommended to erase all keys
before programming the new keys, to ensure that the central locking will
only recognise the keys held by the vehicle owner.
Program remote key
This function will program a new remote key so that the key will be able
to operate the door locks. You will be prompted to activate the remote
key several times by pressing the button on the key fob. This is
necessary for the central locking ECU to record the unique code for the
remote key fob.

Multi-Tester pro Registration
As a security feature, the Multi-Tester pro application must be
registered before the key programming functions are available.
To register your Multi-Tester pro application you must return the
registration card supplied with the software to Autodiagnos. You will
then be given an authorisation code, which you can use to enable the
key programming functions of the software.
To register the Multi-Tester pro, use the “Multi-Tester pro Registration”
option on the main menu. You will be prompted to enter the serial
number of the tester, which can be found, on the back of the unit. You
will then be prompted to enter the authorisation code supplied to you
when you registered the product.
You will also be required to enter the authorisation code each time you
use the application to erase or program transponder keys on a vehicle.

Blink code read-out
To read out DTC:s using the blink code method, do like this.
1. Bridge pin A and B in the diagnostic connector.
Vehicle diagnostic connector (front view)
2.
3.
4.
5.
Turn ignition on.
Count the flashes on the “Check engine” lamp.
Translate them using the list below.
To erase the fault codes, disconnect battery for >20 seconds.
Blink Code interpretation
The code read out always starts with “Code 12” repeated three times,
after this the fault codes are flashed. All codes are repeated three times,
the first digit is flashed with a space of 0.4 seconds, then there is a 1.2
second delay until the second digit is flashed. The delay between codes is
3.2 seconds. Each code is repeated three times.
Example, Code 22 (Throttle potentiometer voltage low):
3.2s
1.2s
(1)
=> 3.2s
0.4s
3.2s
(2)
0.4s
First digit (2)
*3times =>
= Code 12 (start code)
1.2s
“separator“
0.4s
3.2s *3times
Second digit (2)
= Code 22
The sequence is ended by three times flashing of code 12.

Common diagnostic connector locations
Common diagnostic connector locations for recent Vauxhall/Opel models
are listed below. For older vehicles, the diagnostic connector can often be
found in the engine compartment.
Astra-F
16 pin OBD connector located in the fuse compartment to the right hand
side of the steering wheel on RHD vehicles and to the left hand side of
the steering wheel on LHD vehicles. Covering panel can be pulled off to
reveal the complete fuse compartment and diagnostic connector.
Astra-G
16 pin OBD connector located in the central console between the
handbrake and the gearstick. There is a plastic cover that needs to be
removed to find the connector. This can be done with a medium sized
flat-blade screwdriver inserted at the front of the panel (nearest to the
gearstick).
Corsa-B/Tigra
16 pin OBD connector located in the fuse compartment to the right hand
side of the steering wheel on RHD vehicles and to the left hand side of
the steering wheel on LHD vehicles. Covering panel can be pulled off to
reveal the complete fuse compartment and diagnostic connector.
Frontera
16 pin OBD connector mounted vertically just in front of the hinge of the
driver side door.
Omega-B
16 pin OBD connector located in the fuse compartment. There is a large
cover for this compartment directly below the steering wheel. A push
button releases the cover and reveals the fuses and diagnostic connector.

except that the covering panel is best removed by inserting a
screwdriver at the rear of the cover (nearest to the handbrake).
Zafira
16 pin OBD connector located in the central console between the
