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: System voltage

Step 6. Check the wiring harness between E-07 
sunroof motor assembly connector terminal No.2 
and ignition switch (IG2).

NOTE: 

Prior to the wiring harness inspection, check junction 
block connectors C-202 and C-211, and repair if 
necessary.

• 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.

Step 7. Resistance measurement at E-07 sunroof 
motor assembly connector.

(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Continuity between E-07 sunroof motor assembly 

connector terminal No.5 and body earth

OK: 2 

Ω or less

Q: Is the check result normal?

YES : 

Go to Step 9.
