If no motor movement is sensed, the DTC is set. The DSM retries motor operation on the next activation of the seat control switch. If no movement is detected after 250 milliseconds, the DSM disables the output. |
Possible Causes
- Fuse
- Wiring, terminals or connectors
- Seat control switch
- Horizontal motor
- Seat track
- Seat backrest
- Seat head restraint assembly
- Seat cushion extension adjuster
- Lumbar assembly
- DSM
Visual Inspection and Diagnostic Pre-checks
- Verify BJB fuse 72 (30A) is OK.
- Verify BJB fuse 2 (7.5A) is OK.
