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.
