- If the terminals look OK, go to step 5.

5. Reconnect the connector to the driver's under-dash fuse/relay box, turn the ignition switch to ON (II), and do 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 6.

- 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, do 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.





*: Reconnect the connector to the driver's MPCS unit.

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, do 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.





*: Reconnect the connector to the front passenger's MPCS unit.

14. If multiple failures are found on 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.
