Inspection Procedure A-12: Electric tailgate becomes as door-ajar.
CAUTION
Before replacing the ECU, ensure that the input
and output signal circuits are normal.
COMMENTS ON TROUBLE SYMPTOM
With the electric tailgate, when the door-ajar status is
reached before the closing of tailgate, the easy
closer system is activated, and the tailgate is fully
closed automatically. If an abnormality is present to
the easy closer system, check the switches. When
no abnormality is present to the switches, check the
use method of tailgate. (When the tailgate lock
release handle is operated manually, and if the tail-
gate is left as is without being opened, a door-ajar
status may occur. Therefore, be sure not to leave the
tailgate in the middle of operation.)
PROBABLE CAUSES
• Malfunction of the tailgate lock release handle
• Door-ajar switch system failed
• Neutral latch switch system failed
• Half latch switch system failed
• Full latch switch system malfunction
• Tailgate sensor malfunction
• Incorrect operation of tailgate lock release handle
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-III diagnosis code
(1) Operate the electric tailgate.
(2) Check whether a diagnosis code is set in the
electric tailgate control unit.
Q: Is the check result normal?
YES :
Go to Step 2.
NO :
Refer to diagnosis code chart
.
