NOTE:

Prior to the wiring harness inspection, check
intermediate connectors C-16, D-03 and junction
block connector C-202, and repair if necessary.

• Check the power supply line 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 27. Connector check: F-19 power window
motor (rear: RH) connector.

Q: Is the check result normal?

YES :

Repair the connector.

Step 28. Check the wiring harness from F-19
power window motor (rear: RH) connector
terminal Nos.1 and 3 to F-18 power window sub
switch (rear: RH) 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 29.

NO :

Repair the wiring harness.

Step 29. Retest the system.

After the power window sub switch (rear: RH) is
replaced, check that the rear right door power
window can be operated by the power window sub
switch (rear: RH).
(1) Replace the power window sub switch (rear: RH).
(2) Check that the rear right door power window can

be operated by the power window sub switch
(rear: RH).
