STEP 2. Measure the power supply line voltage at 
sunroof-ECU connector E-07.
(1) Remove the headlining. (Refer to GROUP 52A, Headlining 

P.52A-42

.)

(2) Disconnect sunroof-ECU connector E-07 and measure at 

the harness side.

(3) Measure the voltage between terminal 7 and ground.

• Voltage should be approximately 12 volts (battery posi-

tive voltage).

Q: Is measured the voltage approximately 12 volts?

YES : Go to Step 4.
NO :  Go to Step 3.

STEP 3. Check the harness wires between fusible link 
number 8 and sunroof-ECU connector E-07 (terminal No. 
7).

, Harness Connector Inspection. Then go to Step 

4.
Q: Are there any damaged wires between fusible link 

number 8 and sunroof-ECU connector E-07 (terminal 
No. 7)?
YES : Repair or replace the harness wire, then go to Step 4.
NO :  Go to Step 5.

STEP 4. Check the harness wires between sunroof-ECU 
connector E-07 (terminals No.2 and No.6) and ground.
