STEP 3. Check the harness wires between sunroof motor 
assembly connector F-02 (terminal 1) and fusible link (4).

NOTE: Also check intermediate connectors F-24, D-26 and D-
28 for loose, corroded or damaged terminals, or terminals 
pushed back in the connectors. If intermediate connector F-24, 
D-26 or D-28 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 sunroof 
function should now work normally.

STEP 4. 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 “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 7.
NO :  Go to Step 5.

STEP 5. 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 6.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. The sunroof function should now work 

normally.

STEP 6. Check the harness wires between sunroof motor 
assembly connector F-02 (terminal 2) and ignition switch 
(IG2).

NOTE: Also check junction block connectors D-208, D-210, 
intermediate connectors F-24, D-26 and joint connector D-01 
for loose, corroded or damaged terminals, or terminals pushed 
back in the connectors. If junction block connectors D-208, D-
210, intermediate connectors F-24, D-26 and joint connector D-
01 are damaged, repair or replace the damaged component(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 2) and ignition switch (IG2) 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. Check that 
the sunroof function should now work normally.

STEP 7. Check the ground 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 resistance available at the wiring harness side 
of the connector.

(2) Measure the resistance between terminal 5 and ground.

• The resistance should equal 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

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 

P.00E-2

. The sunroof should now work normally.

STEP 9. Check the harness wire between sunroof motor 
assembly connector F-02 (terminal 5) and ground.
Q: Is the harness wire between sunroof motor assembly 

connector F-02 (terminal 5) and ground 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
