Power Window Master Switch Input Test

WARNING: This page is about a different car, the 2011 Honda Pilot, 2010 Honda Pilot, and 2009 Honda Pilot. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Before testing, troubleshoot the multiplex integrated control unit first, using B-CAN System Diagnosis Test Mode A (see TROUBLESHOOTING - B-CAN SYSTEM DIAGNOSIS TEST MODE A ).

Turn the ignition switch to LOCK (0).
Remove the power window master switch (see POWER WINDOW MASTER SWITCH REPLACEMENT ).
Disconnect the 37P connector (A) from the power window master switch (B).

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 5.

With the connector still disconnected, do these input tests at the following connector.

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 6.

WIRE CONDITION TABLE

Cavity	Wire	Test condition	Test: Desired result	Possible cause if desired result is not obtained
4	GRN	Under all conditions	Connect terminals No. 4 and No. 13: The driving position memory switch indicator 2 should come on.	Poor ground (G401) Faulty driving position memory switch An open or high resistance in the wire
6	YEL	Under all conditions	Connect terminals No. 6 and No. 13: The driving position memory switch indicator 1 should come on.	Poor ground (G401) or open in the ground wire Faulty driving position memory switch An open or high resistance in the wire
26	LT BLU	Under all conditions	Connect terminals No. 26 and No. 13: The driving position memory switch lights should come on.	Poor ground (G401) or open in the ground wire Faulty driving position memory switch An open or high resistance in the wire

Reconnect the connector to the power window master switch, and do these input tests.

If any test indicates a problem, find and correct the cause, then recheck the system.
If all the input tests prove OK, the door multiplex control unit must be faulty; replace the power window master switch (see POWER WINDOW MASTER SWITCH REPLACEMENT ).

NOTE: After replacing the power window master switch, reset the power window control unit.

WIRE CONDITION TABLE

Cavity	Wire	Test condition	Test: Desired result	Possible cause if desired result is not obtained
32	BLK	In all ignition switch positions	Measure the voltage to ground: There should be less than 0.2 V.	Poor ground (G401) An open or high resistance in the wire
13	WHT	Under all conditions	Measure the voltage to ground: There should be battery voltage.	Blown No. 23 (10 A) fuse in the under-hood fuse/relay box Faulty under-dash fuse/relay box An open or high resistance in the wire
16	LT GRN	Driver position 2 button pressed	Measure the voltage to ground: There should be less than 0.2 V.	Poor ground (G401) Faulty driving position memory switch An open or high resistance in the wire
16	LT GRN	Driver position 2 button released	Measure the voltage to ground: There should be about 5 V.	Faulty driving position memory switch A short to ground in the wire
17	PUR	Driver position 1 button pressed	Measure the voltage to ground: There should be less than 0.2 V.	Poor ground (G401) Faulty driving position memory switch An open or high resistance in the wire
17	PUR	Driver position 1 button released	Measure the voltage to ground: There should be about 5 V.	Faulty driving position memory switch A short to ground in the wire
19	ORN	Seat SET button pressed	Measure the voltage to ground: There should be less than 0.2 V.	Poor ground (G401) Faulty driving position memory switch An open or high resistance in the wire
19	ORN	Seat SET button released	Measure the voltage to ground: There should be about 5 V.	Faulty driving position memory switch A short to ground in the wire
