STEP 3. Check the ground circuit to the liftgate lock
release handle. Measure the resistance at liftgate lock
release handle connector F-09.
(1) Disconnect liftgate lock release handle connector F-09 and

measure the resistance on the wiring harness side of the
connector.

(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 5.
NO : Go to Step 4.

STEP 4. Check the wiring harness between liftgate lock
release handle connector F-09 (terminal 2) and ground.

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

cuit.

Q: Is the wiring harness between liftgate lock release

handle connector F-09 (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. If the liftgate
lock release handle operates normally, a correct
signal is sent from the liftgate lock release handle.

STEP 5. Check ETACS-ECU connector C-313 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is ETACS-ECU connector C-313 in good condition?

YES : Go to Step 6.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. If the liftgate lock release handle operates

normally, a correct signal is sent from the liftgate lock
release handle.

STEP 6. Check the wiring harness between liftgate lock
release handle connector F-09 (terminal 1) and
ETACS-ECU connector C-313 (terminal 14).

• 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 liftgate lock release

handle connector F-09 (terminal 1) and ETACS-ECU
connector C-313 (terminal 14) in good condition?
YES :
Go to Step 7.
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. If the liftgate
lock release handle operates normally, a correct
signal is sent from the liftgate lock release handle.

STEP 7. Using scan tool MB991958, check data list.
Check the signals related to the liftgate lock release handle
operation.

CAUTION

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958. Refer to GROUP 42B, "How

to connect scan tool (M.U.T.-III)

P.42B-13

."

(2) Turn the ignition switch to the "ON" position.
(3) Check the data list of the ETACS.

• Liftgate lock release handle: from OFF to ON

(4) Turn the ignition switch to the "LOCK" (OFF) position.

OK: Normal condition is displayed.

Q: Is the check result normal?

YES : No action is necessary and testing is complete.
NO : Replace the ETACS-ECU. If the liftgate lock release

handle operates normally, a correct signal is sent from
the liftgate lock release handle.

Item No.
