Immobiliser System Modification F7:PROGRAMMING
IMMOBILISER
| Conditions for checking | Nominal Value |
Affected terminals: -
Possible trouble codes: -
Ignition ON
Note:
During the programming, the SECURITY CODE, MECH. KEY - NO., VEH. IDENT. NO. are programmed consecutively. This procedure is necessary when a new immobiliser control unit is installed in a vehicle.
If a new engine control unit is installed in a vehicle, the security code does not have to be programmed, as it is stored in the immobiliser control unit, not in the engine control unit.
For the valid security code consult the car pass issued to the customer on delivery of the vehicle.
Important:
The security code consists of a four digit number combination and can only be programmed once. Thereafter, it can be neither altered nor deleted; for this reason, proceed with great care when programming a new immobiliser control unit.
Ignition OFF
Press corresponding key in the system main menu to call up desired test functions, select the desired test and confirm with YES. Follow the instructions in the diagnostic tester display.
Note:
The cursor keys can now be used to enter the security code, by selecting the desired digit and confirming with YES. Once all four security code digits have been programmed, input is confirmed with ENTER. The security code can now no longer be altered.
Important:
The security code is always entered consecutively twice. Diagnostic tester than compares the entered codes and evaluates the results.If diagnostic tester shows the display on the right, a fault has occurred during the programming of the security code (diagnostic tester has determined a fault on comparison of the two inputs).
| SECURITY CODE | |

VEH. IDENT. NO.
For further information see corresponding section.If the display on the right appears on diagnostic tester after programming is completed, the immobiliser has been successfully programmed:
