To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before
connecting or disconnecting scan tool MB991958.

(1)

Connect scan tool MB991958. Refer to "How to connect the
Scan Tool (M.U.T.-III) P.54Ad-5."

(2)

Turn the ignition switch to the "ON" position.

(3)

Check the ETACS data list.

Q:Are normal conditions displayed on the "Dr door unlock

switch" and "As door unlock switch"?

YES<Normal conditions are displayed for all the items>:

No action is necessary and testing is complete.

NO<Normal condition is not displayed for item No.271>:

Go to Step 2.

NO<Normal condition is not displayed for item No.272>:

Go to Step 8.

STEP 2. Check front door lock actuator (LH) connector E-21
for loose, corroded or damaged terminals, or terminals
pushed back in the connector.

Q:Is front door lock actuator (LH) connector E-21 in good

condition?

YES:

Go to Step 3.

NO:

Repair or replace the damaged component(s). Refer to

GROUP 00E, Harness Connector Inspection P.00E-2. Check
that the input signal of front door lock actuator (LH) is
normal.

STEP 3. Check the front door lock actuator (LH).
Disconnect front door lock actuator (LH) connector E-21. Then
check continuity between the terminals.

DIAGNOSIS

YES:

Go to Step 4.

NO:

Replace the front door lock actuator (LH). Check that

the input signal of front door lock actuator (LH) is
normal.

STEP 4. Check the ground circuit to the front door lock
actuator (LH). Measure the resistance at front door lock
actuator (LH) connector E-21.

(1)

Disconnect front door lock actuator (LH) connector E-21 and
measure the resistance available at the wiring harness side
of the connector.

ZC6022230005

Connector E-21
(Harness side)

(2)

Measure the resistance value between terminal 1 and
ground.

｠

The resistance should be 2 ohms or less.

Q:Is the measured resistance 2 ohms or less?

YES:

Go to Step 6.

NO:

Go to Step 5.

STEP 5. Check the wiring harness between front door lock
actuator (LH) connector E-21 (terminal 1) and ground.

NOTE:

Also check intermediate connector C-126 for loose,

corroded, or damaged terminals, or terminals pushed back in
the connector. If intermediate connector C-126 is damaged,
repair or replace the connector as described in GROUP 00E,
Harness Connector Inspection P.00E-2.

Q:Is the wiring harness between front door lock actuator

(LH) connector E-21 (terminal 1) 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. Check that the input signal of front
door lock actuator (LH) is normal.

STEP 6. Check ETACS-ECU connector C-301 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.

Q:Is ETACS-ECU connector C-301 in good condition?

YES:

Go to Step 7.

NO:

Repair or replace the damaged component(s). Refer to

GROUP 00E, Harness Connector Inspection P.00E-2. Check
that the input signal of front door lock actuator (LH) is
normal.

STEP 7. Check the wiring harness between front door lock
actuator (LH) connector E-21 (terminal 3) and ETACS-ECU
connector C-301 (terminal 22).

NOTE:

Also check intermediate connector C-127 for loose,

corroded, or damaged terminals, or terminals pushed back in
