Control Unit Input Test: Windshield

2006 Honda Pilot EX, 3.5 YF2, J35A9SECTION Windshield
  1. Before testing the wiper/washer control functions, troubleshoot the multiplex control system (see TROUBLESHOOTING ).

    2. Driver's Multiplex Control Unit 

  2. Remove the driver's multiplex control unit from the driver's under-dash fuse/relay box, and disconnect its connector.
  3. 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.

  4. 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.
