Power Mirror Control Unit Input Test

Power Mirror 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 dashboard lower cover.




3. Disconnect the 26P connector (A) from the power mirror control unit (B).
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 connector 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, the control unit must be faulty; replace it.
