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 

P.00-5

).

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 

P.00-5

).

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 

P.00-5

).

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.

COMMENTS ON TROUBLE SYMPTOM

If the input signal from the sunroof switch is 
abnormal, the sunroof input check response signal 
will not be sent to the SWS communication line.

POSSIBLE CAUSES

• Malfunction of the sunroof assembly

• Malfunction of the sunroof switch

• Damaged harness wires and connectors

DIAGNOSTIC PROCEDURE

Step 1. Check the operation condition of the 
sunroof.
Check that the sunroof works normally.

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Refer to Inspection Procedure F-1 "Sunroof 
does not work at all 

P.54B-186
