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.
  1. Remove the right rear side trim (see TRIM REMOVAL/INSTALLATION - PILLAR AREAS ).
  2. Disconnect the MICU-rear junction box connectors A, C, D and G.
    NOTE: All connectors 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. 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.
