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).So that this system cannot be circumvented, it is necessary to perform adaptation of the anti-theft immobilizer using the VAS 5052 in the On Board Diagnostic (OBD) function.The great availability of equipment options makes adaptation of the Engine Control Module (ECM) necessary (e.g. cruise control system).This “writing” function is not possible with the generic scan tool, therefore it is necessary to use the VAS 5052 in On Board Diagnostic (OBD) function for this purpose.- Procedure to replace Engine Control Module (ECM): Motronic Fuel Injection and Ignition (4-cylinder Turbo); Repair Group 24; Engine Control Module (ECM), replacing.
