Honda CR-V: MICU Input Test
NOTE: Before testing, troubleshoot the B-CAN System Diagnosis Test Mode A.
1. Turn the ignition switch OFF.
2. Disconnect the under-dash fuse/relay box connectors E, F, G, K, R, 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 connector 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.
