3. Is the signal output normal?
  YES
  - Go to " 2 Ground Inspection" procedure.
  NO
  - Thoroughly check fuses or connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
    If the problem is corrected, replace the component and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
Ground Inspection
1. IG "ON" & ENG "OFF".
2. Measure voltage between power voltage of "Rear left side sensor" and ground terminal of "Rear left side sensor" at SJB (Smart Junction Box).
  Specification: Approx. 8.4V

3. Is the signal output normal?
  YES
  - Go to 'INSPECTION OF LIN COMMUNICATION LINE between RPAS-SLH(Rear left side sensor) and BCM [RPAS(Rear Parking Assist Module)]'
  NO
  - Check a circuit between RPAS-SLH(Rear left side sensor) and chassis ground and poor connection. Repair or replace as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
