Circuit Diagram

MICU Input Test

NOTE: Before testing, troubleshoot the B-CAN System Diagnosis Test Mode A.

1. Check the No. 10 (7.5 A) fuse in the under-dash fuse/relay box. lf the fuse is blown, replace it and go to step 2.

2. Disconnect the under-dash fuse/relay box connectors E, F, G, P, Q, R, S, and T.

NOTE: All connector views are wire side of female terminals.

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 connectors still disconnected, make these input tests at the appropriate 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 under-dash fuse/relay box, 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 MICU must be faulty; replace the under-dash fuse/relay box.

Hazard Warning Switch Test/Replacement

1. Remove the center vent.

2. Remove the hazard warning switch (A).

3. Check for continuity between the terminals in each switch position according to the table.

4. If the continuity is not as specified, replace the hazard warning switch.
