NOTE:

Prior to the wiring harness inspection, check
intermediate connectors C-14 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 9. Connector check: F-16 power window
motor (front: RH) connector.

Q: Is the check result normal?

YES :

Go to Step 10.

NO :

Repair the connector.

Step 10. Check the wiring harness from F-16
power window motor (front: RH) connector
terminal Nos.1 and 3 to F-15 power window sub
switch (front: RH) connector terminal Nos.5 and
