STEP 1. Check the steering wheel remote control switch.
STEP 2. Resistance measurement at steering wheel remote control switch connector (ground terminal)
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Measure the resistance between the steering wheel remote control switch connector (ground terminal) and ground.OK: The resistance should be 2 ohms or less
Is the check result normal?
Go to Step 4. Go to Step 3.
STEP 3. Check of open circuit in ground line between steering wheel remote control switch connector and ground
STEP 4. Check the clock spring.
STEP 5. Check of short to power supply, short to ground, and open circuit in ILL+ line between combination meter connector and steering wheel remote control switch connector
STEP 6. Retest the system
