Table 7, F7:PROGRAMMING
IMMOBILISER
| Conditions for checking | Nominal Value |
Affected terminal: -
Possible trouble codes: -
Note:
During the programming, the security code and the engine type are programmed consecutively. This procedure is necessary when a new immobiliser control unit is installed in a vehicle. If a new motronic 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 motronic 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 be programmed once.
Thereafter, it can be neither altered nor deleted; for this reason, proceed with great care when programming.
Ignition "OFF"
Press key F7 in the system main menu, select IMMOBILISER using the arrow keys and confirm with YES.
Follow the instructions on the TECH 1 display.
Note:
The arrow keys can now be used to program the security code, by selecting the desired digit and confirming with YES. TECH 1 automatically moves to the next digit once confirmation has been received. The cursor for the next digit being programmed flashes on the TECH 1. 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. TECH 1 then compares the entered codes and evaluates the results.
| If TECH 1 shows the display on the right, a fault has occurred during the programming of the security code (TECH 1 has determined a fault on comparison of the two inputs). | SECURITY CODE MISMATCH! |
If programming was okay, TECH 1 automatically moves to the next code to be programmed (engine type). F7:PROGRAMMING ENGINE TYPE
| If the display on the right appears on TECH 1 after programming is completed, the immobiliser has been successfully programmed: | F7:PROGRAMMING IMMOBILISER COMPLETED! |
