Driver's Power Seat Control Unit Input Test
Driver's Power Seat Control Unit Input Test1. Remove the driver's power seat mounting bolts.
NOTE: Be careful not to scratch the interior trim.
2. Disconnect the connectors from the driver's power seat control unit (A).
NOTE: Turning the ignition switch ON (II) when the power seat connectors are disconnected may set SRS codes.
3. 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 4.
4. With the power seat control unit connectors still disconnected, make these input tests at the connector.
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, go to step 5.
5. Reconnect the connectors to the driver's power seat control unit, turn the ignition switch ON (II) to keep the system awake, and 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. Substitute with a known-good control unit and recheck.
NOTE: All connector views are from wire side of female terminals.
