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.

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
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 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.

Step 8. Check the wiring harness from F-15
power window sub switch (front: RH) connector
terminal No.4 to C-217 power window connector
terminal No.4.
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
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
7.
• Check the input and output lines for open or short
circuit.
Q: Is the check result normal?
YES :
Go to Step 11.
NO :
Repair the wiring harness.
Step 11. Retest the system.
After the power window sub switch (front: RH) is
replaced, check that the front passenger's door
power window can be operated by the power window
sub switch (front: RH).
(1) Replace the power window sub switch (front:
RH).
(2) Check that the front passenger's door power
window can be operated by the power window
