Pinpoint Test B: B129C:14, B129D:14

  1. B1 CHECK 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 front parking aid sensor Diagnostic Trouble Codes (DTCs) recorded? 

    • Yes  : GO to B2 
    • No  : For DTC B129C:14 or B129D:14, GO to  B3

      For all other Parking Aid Module (PAM) Diagnostic Trouble Codes (DTCs),

      REFER to: PARKING AID .

  2. B2 CHECK THE FRONT BUMPER WIRING HARNESS 
    • Inspect the front bumper wiring harness for opens, shorts, grounds or corrosion.

    Is the front bumper wiring harness OK? 

    • Yes  : GO to B3 
    • No  : REPAIR or INSTALL a new front bumper wiring harness.
  3. B3 CHECK THE SENSOR CIRCUITS FOR OPENS 
    • Ignition OFF.
    • For DTC B129C:14, Disconnect: LH Front Active Park Assist Sensor.
    • For DTC B129D:14, Disconnect: RH Front Active Park Assist Sensor.
    • Disconnect BCM C2280C  .
    • For DTC B129C:14, measure:
      Positive Lead Measurement/Action Negative Lead
      C2280C-7  OHM C1607-1 
      C2280C-11  OHM C1607-2 
      C2280C-35  OHM C1607-3 
    • For DTC B129D:14, measure:
      Positive Lead Measurement/Action Negative Lead
      C2280C-7  OHM C1608-1 
      C2280C-1  OHM C1608-2 
      C2280C-35  OHM C1608-3 

    Are the resistances less than 3 ohms? 

    • Yes  : GO to B4 
    • No  : REPAIR the affected circuit(s).
  4. B4 CHECK THE SENSOR SIGNAL RETURN CIRCUIT FOR A SHORT TO GROUND 
    • For DTC B129C:14, measure:
      Positive Lead Measurement/Action Negative Lead
      C1607-2  OHM Ground
    • For DTC B129D:14, measure:
      Positive Lead Measurement/Action Negative Lead
      C1608-2  OHM Ground

    Is the resistance greater than 10, 000 ohms? 

    • Yes  : GO to B5 
    • No  : REPAIR the circuit.
  5. B5 CHECK THE ACTIVE PARK ASSIST SENSOR 
    • Connect BCM C2280C  .
    • Install a known good active park assist sensor for the suspect sensor.

      REFER to: FRONT ACTIVE PARK ASSIST SENSORS .

    • Ignition ON.
    • Using a diagnostic scan tool, clear the Parking Aid Module (PAM) Diagnostic Trouble Codes (DTCs).
    • Perform the Parking Aid Module (PAM) self-test.

    Is DTC B129C:14 or B129D:14 still present? 

  6. B6 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.
