Step 17. Check the wiring harness from C-226 
ETACS-ECU connector terminal Nos.12 and 13 to 
E-07 rear door lock actuator (LH) connector 
terminal Nos.4 and 6.

NOTE: 

Prior to the wiring harness inspection, check D-15 
intermediate connectors and C-217 junction block 
connector, 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.00-5

).

NO : 

Repair the wiring harness.

COMMENT ON TROUBLE SYMPTOM

If a door or the tailgate cannot be locked or unlocked 
by the central door locking system, the door lock 
actuator or the tailgate lock actuator may be defec-
tive.

POSSIBLE CAUSES

• Malfunction of the door lock actuator

• Malfunction of the tailgate lock actuator

• Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

Step 1. Confirm which door lock actuator is 
defective.

Q: Which door fails to lock correctly?

Driver's door : 

Go to Step 2.

Front passenger's door : 

Go to Step 6.

Rear right door : 

Go to Step 10.

Rear left door : 

Go to Step 14.

Step 2. Connector check: E-15 front door lock 
actuator (RH) connector

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Repair the defective connector.

Step 3. Check the front door lock actuator (RH)
Check that the front door lock actuator (RH) works 
normally. Refer to GROUP 42 

− Door 

P.42-31

.

Q: Is the check result normal?

YES : 

Go to Step 4.

NO : 

Replace the front door lock actuator (RH).

Step 4. Connector check: C-226, C-227 
ETACS-ECU connector

Q: Is the check result normal?

YES : 

Go to Step 5.

NO : 

Repair the defective connector.
