‹› To achieve optimal anti-theft protection for the vehicle, an anti-theft immobilizer was installed. The anti-theft immobilizer is a system for
enabling/locking the Engine Control Module (ECM) (J623).
‹› So that this system cannot be circumvented, it is necessary to perform adaptation of the anti-theft immobilizer using the Vehicle Diagnosis &
Service Syst. (VAS5052) in the On Board Diagnostic (OBD) function.
‹› The great availability of equipment options makes adaptation of the Engine Control Module (ECM) (J623) necessary (e.g. cruise control system).
This "writing" function is not possible with the generic scan tool, therefore it is necessary to use the Vehicle Diagnosis & Service Syst. (VAS5052)
in On Board Diagnostic (OBD) function for this purpose.
‹› If the Engine Control Module (ECM) (J623) must be replaced, the vehicle may be taken to the nearest Audi dealership for ECM and immobilizer
activation instructions.or instructions on obtaining a Vehicle Diagnosis & Service Syst. (VAS5052).
‹› When the electrical connector is disconnected from the Engine Control Module (ECM) (-J623-), adaptation values are erased and content of the
DTC memory remains intact.
