STEP 7. Check the ground circuit to the liftgate lock
actuator. Measure the resistance at liftgate lock actuator
connector F-11.

(1)

Disconnect  liftgate  lock  actuator  connector  F-11  and
measure  the  resistance  on  the  wiring  harness  side  of  the
connector.

Connector F-11 
(harness side)

(2)

Measure  the  resistance  value  between  terminal  2  and
ground.

｠

The resistance should be 2 ohms or less.

Q:Is the measured resistance 2 ohms or less?

YES:

 Go to Step 9.

NO:

 Go to Step 8.

STEP 8. Check the wiring harness between liftgate lock
actuator connector F-11 (terminal 2) and ground.

Q:Is  the  wiring  harness  between  liftgate  lock  actuator

connector  F-11  (terminal  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 the liftgate can be
locked and unlocked normally.

STEP 9. Check the wiring harness between ETACS-ECU
connector C-311 (terminal 1) and liftgate lock actuator
connector F-11 (terminal 1).

NOTE: 

Also check intermediate connector D-12 for loose,

corroded, 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  1)  and  liftgate  lock  actuator  connector

F-11 (terminal 1) in good condition?

YES:

 Go to Step 10.

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 the liftgate can be
locked and unlocked normally.

STEP 10. Retest the system.
Check that the liftgate can be locked and unlocked normally.

Q:Is the check result normal?
