Fault memory of pneumatic system equipment, general notes on diagnosis, advanced information, PSE - AD80.20-P-2000-09B
The fault memory can only be read out and erased using the Hand-Held Tester .
The fault memory of the radio frequency/infrared remote central locking with DAS 3 can be accessed via the HHT mask as follows:
Functions - locking systems - central locking or remote trunk release - fault memory.
It should be noted when reading out the fault memory that not all the fault codes of the CL, RTR, MCS, RHR, MVA systems are stored in the PSE control module (combined) (A37).
The fault codes not in the PSE control module (combined) (A37) can be found in the driver-side signal-acquisition and actuation module (SAM) (N10/1) or lower control field control module (N72).
Fault codes
>Ω Resistance too high
<Ω Resistance too low
Short-circuit to +
Short-circuit to -

- Read out fault memory and note faults.
- Eliminate faults noted in accordance with the fault table.
- Interrupt voltage of pneumatic system equipment for approx. 3 seconds in order to erase the safety memory.
Abbreviations
- PSE PSE control module (combined)
- SAM Driver-side signal-acquisition and actuation module
- UBF Lower control field control module
These abbreviations appear in bold in column 3 of the fault code table and are used to show which control module the faults are stored in.
