STEP 1. Using scan tool MB991958, check data list.
Check the input signals from the front door lock actuators.
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 "How to connect the
Scan Tool (M.U.T.-III)
."
(2) Turn the ignition switch to the "ON" position.
(3) Check the ETACS data list.
• Set the driver's door to "UNLOCK."
• Set the front passenger's door to "UNLOCK." <vehicles
with KOS>
(4) Turn the ignition switch to the "LOCK" (OFF) position.
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.

STEP 3. Check the front door lock actuator (LH).
Disconnect front door lock actuator (LH) connector E-21. Then
check continuity between the terminals.
Q: Is the front door lock actuator (LH) in good condition?
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.
(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.
Check the ground wires for open circuit.
NOTE: Also check intermediate connector C-126 for loose, cor-
roded, 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
.
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
. 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).
Check the input lines for open circuit and short circuit.
NOTE: Also check intermediate connector C-127 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connector C-127 is damaged, repair
or replace the connector as described in GROUP 00E, Harness
Connector Inspection
.
Q: Is the wiring harness between front door lock actuator
(LH) connector E-21 (terminal 3) and ETACS-ECU
connector C-301 (terminal 22) in good condition?
YES : Replace the ETACS-ECU. Check that the input signal
of front door lock actuator (LH) is normal.
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 8. Check front door lock actuator (RH) connector
E-09 for loose, corroded or damaged terminals, or
terminals pushed back in the connector.
Q: Is front door lock actuator (RH) connector E-09 in good
condition?
YES : Go to Step 9.
