• 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.
