(2)Measure the resistance between the tailgate sensor (RH) connector (earth line terminal) and body earth.
OK: Continuity exists (2 Ω or less)

Q. Is the check result normal?





STEP 3. Check of open circuit in TSG line between electric tailgate control unit connector and tailgate sensor (RH) connector.


Q. Is the check result normal?





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


Q. Is the check result normal?





STEP 5. Diagnosis code recheck


(1)Clear all the diagnosis codes stored in the electric tailgate control unit.
