Step 5. Check the wiring harness between E-07 
sunroof motor assembly connector terminal No.1 
and fusible link (5).

NOTE: 

Prior to the wiring harness inspection, check 
intermediate connectors C-124, C-128, 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

Step 6. Voltage measurement at E-07 sunroof 
motor assembly 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-07 sunroof motor assembly 

connector terminal No.2 and body earth

OK: Battery positive voltage

Q: Is the check result normal?

YES : 

Go to Step 8.

NO : 

Go to Step 7.

Step 7. Check the wiring harness between E-07 
sunroof motor assembly connector terminal No.2 
and ignition switch (IG2).

• Check the power supply line to the ignition switch 

(IG2) 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.
