Q. Is the check result normal?

Go to Step 2.

Replace the tailgate sensor (LH).

STEP 2. Resistance measurement at tailgate sensor (LH) connector (earth line terminal).


(1)Disconnect the connector, and measure at the wiring harness side.
(2)Measure the resistance between the tailgate sensor (LH) connector (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 TSG line between electric tailgate control unit connector and tailgate sensor (LH) connector.


Q. Is the check result normal?

Go to Step 5.

Repair the connector(s) or wiring harness.

STEP 4. Check of open circuit in TSL line between electric tailgate control unit connector and tailgate sensor (LH) connector.
