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.
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 under hood 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
- If 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.
- If any test indicates a problem, find and correct the cause, then recheck the system
- If all the input tests prove OK, the multiplex integrated control unit must be faulty, replace the under-dash fuse/relay box assembly.
