Power Windows: Maintenance Honda Pilot I

Resetting the Power Window Control Unit

Resetting the power window control unit is required after performing the following procedures

1. Disconnecting the battery.
2. Removing the No. 1 (20 A) fuse in the driver's under-dash fuse/relay box.
3. Disconnecting the 18P connector from the power window control unit.
4. Removing the window regulator, glass or glass run channel.
5. Disconnecting the driver's door wire harness.

1. Turn the ignition switch OFF, then back ON (II).
2. Move the driver's window all the way down by holding the driver's switch firmly down to the second detent, when the window reaches the bottom, hold the driver's window switch in the AUTO DOWN position for 2 seconds.
3. Move the driver's window all the way up without stopping by holding the driver's switch firmly up to the second detent, when the window reaches the top, hold the driver's window switch in the AUTO UP position for 2 seconds.

If the window does not work in AUTO, reset the power window master switch according to the above procedures again.

1. Before testing the power window control functions, troubleshoot the multiplex control system (see «TROUBLESHOOTING»(ref-243369-S38123892792006082300000) ).
2. Remove the passenger's multiplex control unit from the passenger's under-dash fuse/relay box, and disconnect its connector.
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 passenger's multiplex control unit still disconnected, make these input tests at the passenger's under-dash fuse/relay box socket. 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 .
