PCM2
The PCM2 is provided in 'active production mode' in new vehicles and as a spare part. Each time the vehicle is started, the coded PCM2 code is compared with that 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.
