INPUT SIGNAL PROCEDURES 
<CENTRAL DOOR LOCKING 
SYSTEM>

INSPECTION PROCEDURE B-1: The tailgate lock release handle signal is not received.

CAUTION

• Before replacing the ECU, ensure that the 

power supply circuit, the earth circuit and the 
communication circuit are normal.

• When the ETACS-ECU of vehicles without 

KOS is replaced, the encrypted code of the 
ignition key needs to be registered to the 
ETACS-ECU. (If the encrypted code is not reg-
istered, the engine cannot be started. Regis-
ter the encrypted code as described in 
Immobilizer System 

− How to Register Key ID 

.)

COMMENTS ON TROUBLE SYMPTOM

Input signal from the tailgate lock release handle is 
used to operate the central door locking function. If 
the signal is abnormal, the central door locking func-
tion will not work normally.

PROBABLE CAUSES

• Malfunction of the tailgate lock release handle

• Malfunction of ETACS-ECU

• Damaged wiring harness and connectors

release handle connector (earth line terminal) 
and body earth.

OK: Continuity exists (2 or less)

Q: Is the check result normal?

YES : 

Go to Step 4.

NO : 

Go to Step 3.

STEP 3. Check of open circuit in earth line 
between tailgate lock release handle connector 
and body earth.

Q: Is the check result normal?

CAUTION

During diagnosis, a diagnosis code associated with other system may be set when the ignition switch 
is turned on with connector(s) disconnected. On completion, confirm all systems for diagnosis 
code(s). If diagnosis code(s) are set, erase them all.
