STEP 5. 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 compo-
nent(s) as described in GROUP 00E, Harness Connector 
Inspection

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 6. 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 8.
NO :  Go to Step 7.

STEP 7. 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 
terminals, or terminals pushed back in the connector. 
Repair the wiring harness as necessary. The sunroof 
should now work normally.

STEP 8. Check sunroof switch connector F-01 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.
Q: Is sunroof switch connector F-01 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 function should now work 

normally.

STEP 9. Check the sunroof switch.

Q: Does the check above meet the values in the table?

YES : Go to Step 10.
NO :  Replace the sunroof switch. The sunroof function 

should now work normally.

STEP 10. Check the ground circuit to the sunroof switch. 
Test at sunroof switch connector F-01.
(1) Disconnect the sunroof switch connector F-01 and measure 

at the harness side.

(2) Measure the resistance between terminal 4 and ground.

• The resistance should equal 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Replace the sunroof motor assembly. The sunroof 

function should now work normally.

NO :  Go to Step 11.
