Immobilizer control module, adjusting after replacing (Code Control Module)

WARNING: This page does not describe the selected car, but rather 27 other vehicles, including the 2002 Volkswagen Cabrio, 2001 Volkswagen Cabrio, 2000 Volkswagen Cabrio, 1999 Volkswagen Jetta, and 1999 Volkswagen Golf. However, it is still accessible from the selected car via links, so may be relevant.

For immobilizers of the 3rd generation, the control module for immobilizer has automatic recognition of the baud rate, i.e. coding the control module is not necessary.

The correct data transmission speed between the Engine Control Module (ECM) and the control module for immobilizer is automatically stored in the control module for immobilizer once it is recognized.

NOTE:

If the control module for immobilizer cannot recognize the correct baud rate, the coding is set to the value "00000".
