■ Ground Inspection 

1. IG "ON" & ENG "OFF".
2. Measure voltage between power voltage of "Rear Center Left Sensor" at SJB (Smart Junction Box) and ground terminal of "Rear Center Left Sensor" or LID2 terminal of "Rear Center Left Sensor".

   Specification:  Approx.12V

3. Is the signal output normal?

   YES 

   • Go to 'Inspection of LIN communication line between Rear Center Left Sensor and BCM [PAS (Parking Assist System)] below.
