Honda CR-V: MICU Input Test
1. Before testing, troubleshoot the B-CAN System Diagnosis Test Mode A, and check the No.8 (10 A), No. 10 (7.5 A), and No. 38 (30 A) fuses in the under-dash fuse/relay box.
2. Disconnect under-dash fuse/relay box connectors E, F, 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.
