Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information PSM-U001088

Condition
The Power seat module (PSM) communicates with other control modules in the vehicle via CAN communication.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Communication on the CAN network is interrupted by another control module on the CAN network or by the control module's own message causing interference on the CAN network.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Starting the control module's CAN communication.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.

Substitute value
- Control module shuts itself off ("bus-off").

Possible source
- Short-circuit between the control area network (CAN) wiring.
- Open-circuit in the control area network (CAN) wiring.
- Internal fault in another control module in the same part of the control area network (CAN).
- Damaged power seat module (PSM).

Fault symptom[s]
- Cannot be operated by remote control
- Automatic adjustment of power seat/outer mirror does not work
