54B-494

Inspection Procedure Q-18: The tailgate lock release handle signal is not received.

CAUTION

Whenever the ECU is replaced, ensure that the 
input signal circuit is normal.

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 
function will not work normally.

POSSIBLE CAUSES

• Malfunction of the tailgate lock release handle

• Malfunction of the ETACS-ECU

• Damaged harness wires and connectors

DIAGNOSTIC PROCEDURE

Step 1. Connector check: G-06 tailgate lock 
release handle connector

Q: Is the check result normal?

YES : 

Go to Step 2.
