Step 15. Voltage measurement at F-26 power
window sub switch (front: LH) 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 4 and body earth

OK: System voltage

Q: Is the check result normal?

YES :

Go to Step 18.

NO :

Go to Step 16.

Step 16. Connector check: C-217 power window
relay connector

Q: Is the check result normal?

YES :

Go to Step 17.

NO :

Repair the connector.

Step 17. Check the wiring harness from F-26
power window sub switch (front: LH) connector
terminal No.4 to C-217 power window connector
terminal No.4.

NOTE:

Prior to the wiring harness inspection, check
intermediate connectors C-27 and junction block
connector C-202, and repair if necessary.

• Check the power supply line for open circuit.

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 18. Connector check: F-10 power window
motor (front: LH) connector

Q: Is the check result normal?

YES :

Go to Step 19.

NO :

Repair the connector.

Step 19. Check the wiring harness from F-10
power window motor (front: LH) connector
terminal Nos.1 and 3 to F-26 power window sub
switch (front: LH) connector terminal Nos.5 and
7.

• Check the input and output lines for open or short

circuit.

Q: Is the check result normal?

YES :

Go to Step 20.

NO :

Repair the wiring harness.

Step 20. Retest the system.

After the power window sub switch (front: LH) is
replaced, check that the front passenger's door
power window can be operated by the power window
sub switch (front: LH).
(1) Replace the power window sub switch (front: LH).
(2) Check that the front passenger's door power

window can be operated by the power window
sub switch (front: LH).

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 :

Replace the power window motor assembly
(front: LH).

Step 21. Connector check: F-18 power window
sub switch (rear: RH) connector

Q: Is the check result normal?

YES :

Go to Step 22.

NO :

Repair the connector.

Step 22. Resistance measurement at F-18 power
window sub switch (rear: RH) connector.

(1) Disconnect the connector, and measure at the

wiring harness side.

(2) Resistance between terminal 1 and body earth

OK: 2

Ω or less
