Power Seat Control Unit Input Test

Power Seat Control Unit Input Test

NOTE: Before troubleshooting the DPMS, troubleshoot the multiplex integrated control system first using B-CAN System Diagnosis Test Mode A.

1. Turn the ignition switch OFF.
2. Remove the driver's power seat.

NOTE: Be careful not to scratch the interior trim.




3. Disconnect the connectors from the power seat control unit (A).

NOTE: All connectors view are from wire side of female terminals.

4. Inspect the connector and socket terminals to be sure they are all making good contact.
- If the terminals are bent, loose or corroded, repair them as necessary and recheck the system.
- If the terminals look OK, go to step 5.




5. With the power seat control unit still disconnected, make these input tests at the connectors.
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, the control unit must be faulty; replace it.
