STEP 1. Using scan tool (M.U.T.-IIISE), check the DTC.
STEP 2. Liftgate lock release handle (lock switch and open switch) check
STEP 3. Resistance measurement at lock switch and open switch connector (ground line)
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Measure the resistance between the liftgate lock release handle connector (ground line) and body ground.OK: The resistance should be 2 ohms or less
Is the check result normal?
Go to Step 5. Go to Step 4.
STEP 4. Check of open circuit in ground line between the liftgate lock release handle connector and the body ground.
STEP 5. Check of short to power supply, short to ground or open circuit in GTRQ/GTOP line between the KOS&OSS-ECU connector and the liftgate lock release handle connector.
STEP 6. Keyless operation system communication test
