Fault memory Info key [F8]
In order to be able to assess the fault exactly, the fault memory Info key F8 must be pressed. This information should be saved using the Save key F4 and
printed out. If a fault code is stored with "not present" status and no other problems are present, then the fault memory must be erased.

Fault counter
When a fault first occurs, a fault entry is made in the fault memory and the counter is simultaneously set to 50.
If a fault is present, the counter is incremented by 1 for each "ignition on". The maximum count is 255.
The counter is decremented if the fault is no longer present. The fault memory is automatically erased when the counter
reaches 0.
If the error occurs again when the counter is between 1 and 49, the counter is reset to 50.

Control Module Replacement - PCM2
The PCM2 is provided in 'active production mode' in new vehicles and as a spare part. 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.
