General Information, Version Coding

NOTES:
The PSE provides pressure or vacuum for the following systems:
- Central locking (CL), (pressure or vacuum) - activation via remote central locking (RCL), interior switch (CL) (S6/1s2) and via mechanical key.
- Remote trunk release (RTR), (pressure) - activation via remote trunk release switch (S15) or via remote central locking (RCL). (RTR for model 210 sedan only).
- Retractable rear head restraint (RHR), (vacuum) - activation via RHR unlocking switch (S6/1s3). (RTR for model 210 sedan only).
- Multi-contour seat (OSB), (pressure) - control of the working pressure via pressure switch in the PSE, as soon as the ignition ON signal is received via the CAN-interface. (OSB for model 210 only).
- Manifold Vacuum Assist (MVA), (vacuum) - control of the working vacuum via pressure switch in the PSE, as soon as the ignition ON signal is received via the CAN-interface. (MVA for model 210 only).


Diagnostic Trouble Code (DTC) Memory
- Pneumatic as well as electrical faults of the systems (CL, OSB, MVA, RTR and RHR) are recognized by the PSE and in the DTC memory. The DTC memory which has been integrated into the combination control module (N10-1 or N10-3). DTC memory can only be readout and erased using the Hand-Held-Tester (HHT).


CAUTION !
Erasing the Combination Control Module (N10-1 or N10-3) DTC memory, will also erase the DTC memory for the Convenience Feature (CF) and Mirror, steering column adjustment, heated mirrors (MSC).


Additional components of the PSE:
- Heated rear window relay
- ATA control module

Replacement of the combination control module (N10-1 or N10-3):
- Combination control modules being replaced must be programmed and version coded prior to connecting to the vehicle electrical system.
