SYMPTOM PROCEDURES

SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR

54B-61

COMMENT ON TROUBLE SYMPTOM
If the central door locking system does not work at
all, the door lock actuator (front: LH) or the
ETACS-ECU may be defective.

POSSIBLE CAUSES

•

Malfunction of the door lock actuator (front: LH)

•

Malfunction of the ETACS-ECU

•

Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

Step 1. Check the power supply circuit.

When the ignition switch is turned to the LOCK
(OFF) position, check if the hazard warning lamps
illuminate.

Q: Is the check result normal?

YES :

Go to Step 2.

NO :

Refer to inspection procedure A-2 "Check
the ETACS-ECU battery power supply
circuit"

P.54B-52

.

Step 2. Pulse check

Check the input signal from the driver's door lock
actuator switch.

OK: The MUT-II/III sound or the voltmeter
needle fluctuate.

Q: Is the check result normal?

YES :

Go to Step 3.

NO :

Refer to inspection procedure N-12 "The
driver's door lock actuator signal is not
received <L.H. drive vehicles>

P.54B-350

."

Step 3. Connector check: E-11 door lock actuator
(front: LH) connector

Q: Is the check result normal?

YES :

Go to Step 4.

NO :

Repair the defective connector.

Step 4. Check the door lock actuator (front: LH)

Check that the door lock actuator (front: LH) works
normally. Refer to GROUP 42

−

Door

P.42-35

.

Q: Is the check result normal?

YES :

Go to Step 5.

NO :

Replace the door lock actuator (front: LH).

Step 5. Connector check: C-217 ETACS-ECU
connector

Q: Is the check result normal?

YES :

Go to Step 6.

NO :

Repair the defective connector.

Step 6. Check the wiring harness between C-217
ETACS-ECU connector terminal No. 2 and fusible
link (1).

NOTE:

Prior to the wiring harness inspection, check
intermediate connector C-116 and junction block
connector C-204, and repair if necessary.

•

Check the power supply line for open or short
circuit.

Q: Is the check result normal?

YES :

Go to Step 7.

NO :

Repair the wiring harness.

Step 7. Retest the system.

Check that the central door locking system works
normally.

Q: Is the check result normal?

YES :

The trouble can be an intermittent

malfunction (Refer to GROUP 00

−

Cope with Intermittent Malfunction

P.00-6

).

NO :

Replace the ETACS-ECU.
