Inspection Procedure C-6: The tailgate cannot be opened or closed.

COMMENT ON TROUBLE SYMPTOM

If a door or the tailgate can not be locked or unlocked
by the central door locking system, the tailgate lock
actuator or the ETACS-ECU may be defective.

POSSIBLE CAUSES

• Malfunction of the tailgate lock actuator

• Malfunction of the ETACS-ECU

• Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

Step 1. Check that the central door locking
system and the keyless entry system operate.
Check that the doors (excluding the tailgate) are
locked and unlocked normally when the central door
locking and keyless entry systems are operated.
