Multiplex Integrated Control Unit Input Test
Multiplex Integrated Control Unit Input Test1. Remove the left side kick panel.
2. Disconnect the under-dash fuse/relay box connectors D, E, H, I, J, K, N, P and X.
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. With the connectors still disconnected from the underhood fuse/relay box, make these input tests at the connector(s).
- If any test indicates a problem, find and correct the cause, then recheck the system.
- It all the input tests prove OK, go to step 5.
5. Reconnect the connectors to the under-dash fuse/relay box, and make sure these input tests at the appropriate connectors on the under-dash fuse/relay box.
- It any test indicates a problem, find and correct the cause, then recheck the system.
- It all the input tests prove OK, the multiplex integrated control unit must be faulty, replace the under-dash fusel relay box assembly.
