NOTE: Also check intermediate connectors D-26, D-28 and F-
24 for loose, corroded, or damaged terminals, or terminals 
pushed back in the connector. If intermediate connector D-26, 
D-28 or F-24 is damaged, repair or replace the damaged com-
ponent(s) as described in GROUP 00E, Harness Connector 
Inspection 

P.00E-2

.

Q: Is the wiring harness between sunroof motor assembly 

connector F-02 (terminal 1) and fusible link (4) in good 
condition?
YES : No action is necessary and testing is complete.
NO :  The wiring harness may be damaged or the 

connector(s) may have loose, corroded or damaged 
terminals, or terminals pushed back in the connector. 
Repair the wiring harness as necessary. The system 
should communicate with the sunroof motor assembly 
(sunroof-ECU) normally.

STEP 7. Check the ignition switch (IG2) circuit to the 
sunroof motor assembly. Test at sunroof motor assembly 
connector F-02.
(1) Disconnect sunroof motor assembly connector F-02 and 

measure the voltage available at the wiring harness side of 
the connector.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal 2 and ground.

• The voltage should be approximately 12 volts (battery 

positive voltage).

Q: Is the measured voltage approximately 12 volts (battery 

positive voltage)?
YES : Go to Step 10.
NO :  Go to Step 8.

STEP 8. Check sunroof motor assembly connector F-02 for 
loose, corroded or damaged terminals, or terminals 
pushed back in the connector.
Q: Is sunroof motor assembly connector F-02 in good 

condition?
YES : Go to Step 9.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection
