General information on the fault memory

Fault code setting conditions
Fault codes can be set in several circumstances, e.g.:

- Battery disconnected.
- Plug connections disconnected.
- Power failure.

In these situations, no fault is present in the system and the fault memory must be erased.

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 the status "not present" and no other problems are present, then the fault memory must be erased.









'*' display in the 'Control units' and 'PCM2/ CDR23 MOST component check' menu
Different required and actual installed components lists

When the 'automatic control module search' is complete, an asterisk ('*') appears in front of the control module description 'PCM2' in the 'Control units' menu, as well as in the 'PCM2 MMI function selection' in front of the entry 'MOST required installed components list' if the 9588 Porsche System Tester II establishes a difference between the required and actual installed components list and there is no fault code in one of the fault memories of the MOST control modules.

If there is a fault code present in one of the MOST control modules, the display '*' is only shown in the 'PCM2 MMI function selection' in front of the line 'MOST required installed components list'.

If an asterisk is displayed in the Control units menu, an existing fault code has priority and a '#' is set.

Vehicle hand-over
The PCM2 is converted to delivery mode (low-current mode) in production. As known from other systems (alarm system, instrument cluster, roll-over bar), the PCM2 must be activated with the 9588 Porsche System Tester II.

1. Connect and start the 9588 Porsche System Tester II and switch on the ignition.
2. Select 'Special functions' in the Vehicle type menu and confirm with the [>>] key.
3. Select 'Vehicle hand-over' in the Control units menu and confirm with the [>>] key.
4. Follow the instructions of the 9588 Porsche System Tester II:

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. Provided 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.
