POSSIBLE CAUSES
• Malfunction of the front power window sub
switch, rear power window sub switch (RH) or
rear power window sub switch (LH)
• Malfunction of the front power window regulator
motor (RH) <LH drive vehicles>, front power win-
dow regulator motor (LH) <RH drive vehicles>,
rear power window regulator motor (RH) or rear
power window regulator motor (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?
Front passenger's door <LH drive vehicles> :
Go
to Step 3.
Front 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: E-14 front power
window sub switch connector
Q: Is the check result normal?
YES :
Go to Step 4.
NO :
Repair the connector.
Step 4. Resistance measurement at E-14 front
power window sub switch connector
(1) Disconnect the connector, and measure at the
wiring harness side.
(2) Resistance between E-14 front power window
sub switch connector 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 E-14 front
power window sub switch connector terminal
No.1 to body earth.
NOTE:
Prior to the wiring harness inspection, check interme-
diate connector C-110, 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 E-14 front power
window sub switch connector
(1) Disconnect the connector, and measure at the
wiring harness side.
(2) Turn the ignition switch to the ON position.
(3) Voltage between E-14 front power window sub
switch connector 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-224 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 E-14 front
power window sub switch connector terminal
No.4 to C-224 power window relay connector
terminal No.4.
NOTE:
Prior to the wiring harness inspection, check interme-
diate connectors C-110 and junction block connector
C-211, 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: E-11 front power
window regulator motor (RH) connector
Q: Is the check result normal?
YES :
Go to Step 10.
NO :
Repair the connector.
Step 10. Check the wiring harness from E-11
front power window regulator motor (RH)
connector terminal Nos.1 and 4 to E-14 front
power window sub switch connector terminal
Nos.5 and 7.
• Check the input and output lines for open or short
circuit.
