STEP 21. Check the wiring harness between liftgate lock 
actuator connector F-11 (terminal No. 2) and ground.

• Check the ground line for open circuit.

Q: Is the wiring harness between liftgate lock actuator 

connector F-11 (terminal No. 2) 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. Verify that all 
the doors and the liftgate can be locked and unlocked 
normally.

STEP 22. Check ETACS-ECU connector C-311 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.
Q: Is ETACS-ECU connector C-311 in good condition?

YES : Go to Step 23.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. Verify that all the doors and the liftgate can 

be locked and unlocked normally.

STEP 23. Check the wiring harness between ETACS-ECU 
connector C-311 (terminal No. 1) and liftgate lock actuator 
connector F-11 (terminal No. 1).

• Check the power supply line for open circuit and short cir-

cuit.

NOTE: Also check intermediate connector D-12 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the 
connector. If intermediate connector D-12 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 ETACS-ECU connector 

C-311 (terminal No. 1) and liftgate lock actuator 
connector F-11 (terminal No. 1) in good condition?
YES : Go to Step 24.
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. Verify that all 
the doors and the liftgate can be locked and unlocked 
normally.

STEP 24. Retest the system.
Check that the central door locking system works normally.
Q: Is the check result normal?

YES : No action is necessary and testing is complete.
NO :  Replace the ETACS-ECU. Check that the central door 

locking system normally.
