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.
