(front: RH), the power window sub switch (rear:
RH) or the power window sub switch (rear: LH)

• Malfunction of the power window motor (front:

RH), the power window motor (rear: RH) or the
power window motor (rear: LH)

• Damaged harness wires and connectors

• Malfunction of the power window motor (front:

LH), the power window motor (rear: RH) or the
power window motor (rear: LH)

• Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

Step 1. Check the power window main switch.

Check that the power window lock switch is turned
off.

Q: Is the check result normal?

YES :

Go to Step 2.

NO :

Turn off the power window lock switch.

Step 2. Determine a trouble spot.

Q: Which power window does not work?

Passenger's door <LH drive vehicles> :

Go to Step

3.

Passenger's door <RH drive vehicles> :

Go to Step

12.

Rear right door :

Go to Step 21.

Rear left door :

Go to Step 30.

Step 3. Connector check: F-15 power window sub
switch (front: RH) connector

Q: Is the check result normal?

YES :

Go to Step 4.

NO :

Repair the connector.

Step 4. Resistance measurement at F-15 power
window sub switch (front: RH) connector.

(1) Disconnect the connector, and measure at the

wiring harness side.

(2) Resistance between terminal No.1 and body

earth.

OK: 2

Ω or less

Q: Is the check result normal?

YES :

Go to Step 6.

NO :

Go to Step 5.

Step 5. Check the wiring harness from F-15
power window sub switch (front: RH) connector
terminal No.1 to body earth.

NOTE:

Prior to the wiring harness inspection, check
intermediate connector C-14 and repair if necessary.

• Check the earth wires for open circuit.

Q: Is the check result normal?

YES :

The trouble can be an intermittent

malfunction (Refer to GROUP 00

− How to

Cope with Intermittent Malfunction

P.00-5

).

NO :

Repair the wiring harness.

Step 6. Voltage measurement at F-15 power
window sub switch (front: RH) connector.

(1) Disconnect the connector, and measure at the

wiring harness side.

(2) Turn the ignition switch to the ON position.

(3) Voltage between terminal No.4 and body earth

OK: System voltage

Q: Is the check result normal?

YES :

Go to Step 9.

NO :

Go to Step 7.

Step 7. Connector check: C-217 power window
relay connector

Q: Is the check result normal?

YES :

Go to Step 8.

NO :

Repair the connector.
