Power Window SUBSWITCH Inspection

Measure the voltage at each terminal is as indicated in the TERMINAL VOLTAGE REFERENCE .

If the voltage is not as specified in the TERMINAL VOLTAGE REFERENCE , inspect the parts under "Inspection item (s)".
- If the system does not work properly even though the parts or related wiring harnesses do not have any malfunction, replace the power window sub switch.

Go to TERMINAL VOLTAGE REFERENCE .

TERMINAL VOLTAGE REFERENCE

Terminal	Signal name	Connected to	Measured condition	Voltage (V)/Continuity	Inspection item (s)
A	Open output	Power window motor	While door glass is opening	1.0 or less	Power window motor
A	Open output	Power window motor	While door glass is closing	B+	Power window motor
B	GND	Body ground	Under any condition: Inspect for continuity to ground	Continuity detected	GND
C	Serial	Power window main switch	Because this terminal is for communication, good/no good judgment by terminal voltage is not possible. Inspect the wiring harness between power window subswitch terminal C and power window main switch terminal H for the following: Short to ground Open circuit		Power window main switch
D	GND	Power window motor	Under any condition: Inspect for continuity to ground	Continuity detected	Power window motor
E	Pulse 1	Power window motor	Door glass moving	Approx. 6	Power window motor
E	Pulse 1	Power window motor	Door glass stopped	0 or B+	Power window motor
G	Pulse 2	Power window motor	Door glass moving	Approx. 6	Power window motor
G	Pulse 2	Power window motor	Door glass stopped	0 or B+	Power window motor
I	Power supply	Power window motor	Ignition switch at ON	B+	Power window motor
J	Power cut	Power window main switch	Ignition switch at ON Power cut switch at off	0.25	Related wiring harness Power window subswitch
			Ignition switch at ACC or LOCK	1.0 or less
			Power cut switch at on	1.0 or less
K	Close output	Power window motor	Door glass moving	Approx. 6	Power window motor
K	Close output	Power window motor	Door glass stopped	LO or less	Power window motor
L	Power supply	P/W 30 A fuse	Under any condition	B+	P/W 30 A fuse

Turn the ignition switch to ON position, and verify the LED illuminates.
- If not as specified, replace the power window subswitch.
