Step 21. Check the wiring harness from C-217
ETACS-ECU connector terminal Nos. 12 and 13 to
F-06 tailgate lock actuator connector terminal
Nos. 2 and 3.

NOTE:

Prior to the wiring harness inspection, check
intermediate connector F-05 and junction block
connector C-221, and repair if necessary.

•

Check the input and output lines for open circuit.

Q: Is the check result normal?

YES :

The trouble can be an intermittent

malfunction (Refer to GROUP 00

−

How to

Cope with Intermittent Malfunction

P.00-6

).

NO :

Repair the wiring harness.

INSPECTION PROCEDURE C-3: The central door locking system can not be operated by means of the
front passenger's door lock key cylinder.

CAUTION

Whenever the ECU is replaced, ensure that the
input and output signal circuits are normal.

COMMENTS ON TROUBLE SYMPTOM
If the central door locking system does not work by
means of the front passenger's door lock key
cylinder, the front passenger's door lock key cylinder
or the ETACS-ECU may be defective.

POSSIBLE CAUSES

•

Malfunction of the front passenger's door lock key
cylinder

•

Malfunction of the ETACS-ECU

•

Damaged harness wires and connectors

DIAGNOSTIC PROCEDURE

Step 1. Check the operation of the central door
locking system.

Check that the central door locking system works
normally by means of the driver's door lock key
cylinder and inside lock knob.

Q: Is the check result normal?

YES :

Go to Step 2.

NO :

Refer to inspection procedure C-1 "Central
door locking system does not work at all
<L.H. drive vehicles>

P.54B-60

or <R.H.

drive vehicles>

P.54B-63

."

Step 2. Pulse check

Check the input signal from the front passenger’s
door lock key cylinder switch.

OK: The MUT-II/III sounds or the voltmeter
needle fluctuates.

Q: Is the check result normal?

YES :

Go to Step 3.

NO :

Refer to inspection procedure N-18 "The
front passenger's door lock key cylinder
switch signal is not received <L.H. drive
vehicles>

P.54B-380

or <R.H. drive

vehicles>

P.54B-383

."

Step 3. Retest the system.

Check that the central door locking system works
normally by means of the front passenger's door lock
key cylinder.

Q: Is the check result normal?

YES :

The trouble can be an intermittent

malfunction (Refer to GROUP 00

−

How to

Cope with Intermittent Malfunction

P.00-6

).

NO :

Replace the ETACS-ECU.

INSPECTION PROCEDURE C-4: The Ignition Key Reminder Function does not Work Normally.

CAUTION

Whenever the ECU is replaced, ensure that the
input and output signal circuits are normal.

COMMENTS ON TROUBLE SYMPTOM
If the key reminder function does not work normally,
the input signal circuits below or the ETACS-ECU
may be defective.

•

Key reminder switch

•

Driver's door switch

•

Driver's door lock actuator

POSSIBLE CAUSES

•

Malfunction of the key reminder switch

•

Malfunction of the driver's door switch

•

Malfunction of the driver's door lock actuator

•

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 signals below which are related to
