MICU - Rear Junction Box Input Test
WARNING: This page is about a different car, the 2006 Honda Odyssey and 2005 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.
- Remove the right rear side trim (see TRIM REMOVAL/INSTALLATION - PILLAR AREAS ).
- Disconnect the MICU-rear junction box connectors A, C, D and G.NOTE: All connectors are wire side of female terminals.
- 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.
- Reconnect the connectors to the MICU-rear junction box and make these input tests at the appropriate connectors on the MICU-rear junction box.
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, replace the MICU-rear junction box.
