  1. G1 RETRIEVE THE DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE PARKING AID MODULE (PAM) SELF-TEST 
    • Using a scan tool, perform the Parking Aid Module (PAM) self-test.
    • Check the Parking Aid Module (PAM) Diagnostic Trouble Codes (DTCs) from the self-test.

    Are multiple rear parking aid sensor Diagnostic Trouble Codes (DTCs) recorded? 

    • Yes  : GO to G2 
    • No  : For Diagnostic Trouble Codes (DTCs) B1B44:12, B1B46:12, B1B48:12 or B1B50:12, GO to  G3

      For all other Diagnostic Trouble Codes (DTCs), REFER to the Parking Aid Module (PAM) DTC Chart .

  2. G2 CHECK THE FRONT BUMPER WIRING HARNESS 
    • Ignition OFF.
    • Inspect the front bumper wiring harness for opens, shorts, grounds, or corrosion.

    Is the front bumper wiring harness OK? 

    • Yes  : GO to G3 
    • No  : REPAIR or INSTALL a new front bumper wiring harness.
  3. G3 CHECK THE FRONT PARKING AID SENSOR CIRCUITRY FOR A SHORT TO VOLTAGE 
    • Disconnect: suspect parking aid sensor(s).
    • Disconnect BCM C2280C  .
    • Ignition ON.
    • For DTC  B1B36:12, measure:
      Positive Lead Measurement/Action Negative Lead
      C1431-2  VOLTAGE Ground
    • For DTC  B1B38:12, measure:
      Positive Lead Measurement/Action Negative Lead
      C1430-2  VOLTAGE Ground
    • For DTC  B1B40:12, measure:
      Positive Lead Measurement/Action Negative Lead
      C1428-2  VOLTAGE Ground
    • For DTC  B1B42:12, measure:
      Positive Lead Measurement/Action Negative Lead
      C1429-2  VOLTAGE Ground

    Is any voltage present? 

    • Yes  : REPAIR the circuit in question.
    • No  : GO to G4 
  4. G4 CHECK THE REAR PARKING AID SENSOR CIRCUITRY FOR A SHORT TOGETHER 
    • Ignition OFF.
    • For DTC  B1B36:12, measure:
      Positive Lead Measurement/Action Negative Lead
      C1431-2  OHM C1431-1 
    • For DTC  B1B38:12, measure:
      Positive Lead Measurement/Action Negative Lead
      C1430-2  OHM C1430-1 
    • For DTC  B1B40:12, measure:
      Positive Lead Measurement/Action Negative Lead
      C1428-2  OHM C1428-1 
    • For DTC  B1B42:12, measure:
      Positive Lead Measurement/Action Negative Lead
      C1429-2  OHM C1429-1 

    Is the resistance greater than 10, 000 ohms? 

    • Yes  : If all the sensor Diagnostic Trouble Codes (DTCs) are set, GO to G5 

      If one or more (but not all) parking aid sensor(s) recorded Diagnostic Trouble Codes (DTCs), INSTALL a new sensor(s) for the one in question.

      REFER to: FRONT PARKING AID SENSOR  .

    • No  : REPAIR the circuits in question.
  5. G5 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION 
    • Ignition OFF.
    • Disconnect and inspect all BCM  connectors.
    • Repair:
      • corrosion (install new connector or terminals - clean module pins)
      • damaged or bent pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary
    • Reconnect the BCM  connectors. Make sure they seat and latch correctly.
    • Operate the system and determine if the concern is still present.

    Is the concern still present? 

    • Yes  : CHECK OASIS  for any applicable Technical Service Bulletins (TSBs). If a Technical Service Bulletin (TSB) exists for this concern, DISCONTINUE this test and FOLLOW Technical Service Bulletin (TSB) instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new BCM  .

      REFER to: BODY CONTROL MODULE (BCM) .

    • No  : The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
