Driver's MPCS Unit Input Test

Driver's MPCS Unit Input Test

1. Turn the ignition switch OFF.
2. Remove the driver's door panel.




3. Disconnect the driver's MPCS unit (A) connectors A (40P) and B (14P).
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 connectors 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, go to step 6.




6. Reconnect the connectors to the driver's MPCS unit, 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; replace the driver's MPCS unit and go to step 7.

7. Reset the power window control unit.
