Step 7. Check the wiring harness between C-217
power window relay connector terminal No.4 and
F-05 power window main switch connector
terminal No.6.
NOTE:
Prior to the wiring harness inspection, check
intermediate connectors C-27 <LH drive vehicles>,
C-14 <RH drive vehicles> 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 8. Resistance measurement at the F-05
power window main switch connector.
(1) Remove the power window main switch, and
measure at the wiring harness side.
(2) Resistance between F-05 power window main
switch connector terminal No.2 and body earth
OK: 2
Ω or less
Q: Is the check result normal?
YES :
Go to Step 10.
NO :
Go to Step 9.
Step 9. Check the wiring harness between F-05
power window main switch connector terminal
No.2 and body earth.
NOTE:
Prior to the wiring harness inspection, check
intermediate connectors C-27 <LH drive vehicles>,
C-14 <RH drive vehicles>, and repair if necessary.
• Check the earth wires for open circuit.

YES :
The trouble can be an intermittent
malfunction (Refer to GROUP 00
− How to
Cope with Intermittent Malfunction
NO :
Repair the wiring harness.
Step 10. Retest the system.
Check that each switch signal is received by
operating the power window main switch.
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 :
Replace the power window main switch.
Inspection Procedure Q-10: When the sunroof switch is operated, the switch signals are not received.
CAUTION
Whenever the ECU is replaced, ensure that the
input signal circuit is normal.
