PCM2 Gateway

Control module replacement - PCM2
The PCM2 is supplied in 'production mode on' in new vehicles and as a spare part. If production mode is coded out, the control module is operational again following a restart (vehicle must be locked and secured).

Each time the vehicle is started, the model range code that is stored is compared with the code in the instrument cluster. If no match is found, the device switches off after 30 seconds and the 'PROTECTED' message appears in the display. The device is not operational.

If a match is found, the device is operational. No further checks are made while the device is connected to the vehicle electrical system.
