NOTE: Also check junction block connectors D-208, D-210, 
intermediate connectors D-01, D-26 and F-24 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the 
connector. If junction block connector D-208, D-210, intermedi-
ate connectors D-01, D-26 or F-24 is 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 the 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. The system 
should communicate with the sunroof motor assembly 
(sunroof-ECU) normally.

STEP 8. 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 value 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 9.

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

Q: Is the wiring harness 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 system 
should communicate with the sunroof motor assembly 
(sunroof-ECU) normally.

STEP 10. Check ETACS-ECU connector D-224 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.

Q: Is ETACS-ECU connector D-224 in good condition?

YES : Go to Step 11.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. The system should communicate with the 

sunroof motor assembly (sunroof-ECU) normally.

NOTE: Also check intermediate connectors D-26, F-24 and 
joint connector D-02 for loose, corroded, or damaged terminals, 
or terminals pushed back in the connector. If intermediate con-
nector D-26, F-24 or joint connector D-02 is damaged, repair or 
replace the damaged component(s) as described in GROUP 
00E, Harness Connector Inspection

.

Q: Is the wiring harness between sunroof motor assembly 

connector F-02 (terminal 10) and ETACS-ECU connector 
D-224 (terminal 21) in good condition?
YES : Go to Step 12.
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 12. Replace the ECU.
(1) Replace the sunroof motor assembly.
(2) The system should communicate with the sunroof motor 

assembly normally.

Q: Can the system communicate with the sunroof motor 

assembly?
YES : No action is necessary and testing is complete.
NO :  Replace the ETACS-ECU. The system should 

communicate with the sunroof motor assembly
