Wipers/washers: Other Honda Pilot I

Windshield

1. Before testing the wiper/washer control functions, troubleshoot the multiplex control system (see «TROUBLESHOOTING»(ref-174054-S13252150322005051900000) ).

Driver's Multiplex Control Unit

Scheme 10

Scheme 11

Scheme 12

1. Remove the driver's multiplex control unit from the driver's under-dash fuse/relay box, and disconnect its connector.
2. Inspect all connector and socket terminals to be sure they are 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.
3. With the driver's multiplex control unit still disconnected, make these input tests at the connector and driver's under-dash fuse/relay box sockets. If any test indicates a problem, find and correct the cause, then recheck the system. If all the input tests prove OK, driver's multiplex control unit must be faulty; replace it.
