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).
