Power Mirror Circuit Input Test

Power Mirror Circuit Input Test

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

MICU

1. Turn the ignition switch OFF.
2. Remove the left side kick panel.




3. Disconnect driver's under-dash fuse/relay box connector P (30P).
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. Reconnect the connector to the driver's under-dash fuse/relay box.
- 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 6.

Drivers MPCS Unit

6. Remove the driver's door panel.




7. Disconnect driver's MPCS unit connector A (40P).
8. Inspect the connector and socket terminal 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 9.




9. 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, go to step 10

Passenger's MPCS Unit

10. Remove the passenger's door panel.




11. Disconnect passenger's MPCS unit connector A (28P).
12. 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 13.




13. 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, go to step 14.

14. If multiple failures are found on the more than one control unit, replace the driver's under-dash fuse/relay box (includes the MICU). If input failures are related to a particular control unit, replace the control unit.
