General Information: Notes

EuroVans from 12.00 are equipped with Immobilizer Generation III.

NOTE: On Board Diagnostic of the anti-theft immobilizer system is to be carried out exclusively using the VAS 5051 Vehicle Diagnostic Testing and Information System.

In addition to the normal data exchange between the immobilizer control module and ignition key, Gen. III includes data exchange between the immobilizer control module and Engine Control Module (ECM).

Data exchange between the Immobilizer control module and ECM takes place over the "W" circuit or vehicle CAN-Bus network (CAN-Bus implemented as a running change during m.y. 2001 production).

Determine data exchange method using Function 08, Read Measuring Value Block, Display Group 001.

If a baud rate value appears in display field 1, data exchange is via the "W"circuit. If the text "Data Bus" appear in display field 1, data exchange is via the vehicle CAN Bus network.

Anti-theft immobilizer system consists of:

Immobilizer control module
Adapted Engine Control Module (ECM)
Induction coil at ignition lock
Adapted ignition keys with electronics (transponder/response read memory)
