DIAGNOSIS PROCEDURE
STEP 1. Neutral switch inspection.
Check the tailgate latch (refer to ).
Q.
Is the check result normal?
Go to Step 2.
Replace the tailgate latch.
STEP 2. Resistance measurement at tailgate latch connector (neutral
switch earth line terminal).
|
(1)Disconnect the connector, and measure at the wiring harness side.
|
|
(2)Measure the resistance between the tailgate latch connector (neutral switch earth
line terminal) and body earth. OK: Continuity exists (2 Ω or less)
|
Q.
Is the check result normal?
Go to Step 4.
Go to Step 3.
STEP 3. Check of open circuit in earth line between tailgate latch
connector (neutral switch terminal) and body earth.
Q.
Is the check result normal?
Go to Step 5.
Repair the connector(s) or wiring harness.
STEP 4. Check of open circuit in NTL line between electric tailgate
control unit connector and tailgate latch connector.
Q.
Is the check result normal?
Go to Step 5.
Repair the connector(s) or wiring harness.
STEP 5. Diagnosis code recheck
|
(1)Clear all the diagnosis codes stored in the electric tailgate control unit.
|
|
(2)Operate the electric tailgate.
|
|
(3)Check whether a diagnosis code is set in the electric tailgate control unit.
|
Q.
