Step 6. Check the wiring harness between E-07 
sunroof motor assembly connector terminal No.1 
and the fusible link (5).

NOTE: 

Prior to the wiring harness inspection, check 
intermediate connector C-124 and 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 

− How to 

Cope with Intermittent Malfunction 

P.00-5

).

NO : 

Repair the wiring harness.

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

(1) Disconnect the sunroof motor assembly 

connector, and measure at the harness side.

(2) Ignition switch: ON

(3) Check the voltage between the 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 9.

NO : 

Go to Step 8.

Step 9. Resistance measurement at the E-07 
sunroof motor assembly connector.

(1) Disconnect the sunroof motor assembly 

connector, and measure at the harness side.

(2) Check the resistance 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 11.

NO : 

Go to Step 10.

Step 10. Check the wiring harness between E-07 
sunroof motor assembly connector terminal No.5 
and body earth.

• Check body earth 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 11. Retest the system.
