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 
the key reminder function.

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