Pinpoint Test

NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
  1. RETRIEVE THE DTCs  FROM THE PAM SELF-TEST
    1. Using a scan tool, perform the PAM self-test.

    Are multiple DTCs recorded? 

    1. Yes: GO to .
    2. No: For DTC B129C:14 or DTC B129D:14, GO to  3.

      For all other DTCs  , REFER to DTC CHART: PARKING AID MODULE (PAM) .

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

    Is the bumper wiring harness OK? 

    1. Yes: GO to .
    2. No: REPAIR or INSTALL a new bumper wiring harness. CLEAR the DTCs  .
  3. CHECK THE ACTIVE PARK ASSIST SENSOR CIRCUITRY FOR OPENS
    1. Ignition OFF.
    2. Disconnect: Suspect Active Park Assist Sensor.
    3. Disconnect: PAM.
    4. For DTC B129C:14, measure:
      PAM LH Active Park Assist Sensor
      G08034307
      G08034308
      C3267 C1607
      Pin Circuit Measurement / Action Pin Circuit
      9 LMP07 (BU/WH)
      G08034309
      1 LMP07 (BU/WH)
      7 VMP20 (GY/OG)
      G08034310
      2 VMP20 (GY/OG)
      12 RMP07 (GN/WH)
      G08034311
      3 RMP07 (GN/WH)
    5. For DTC B129D:14, measure:
      PAM RH Active Park Assist Sensor
      G08034312
      G08034313
      C3267 C1608
      Pin Circuit Measurement / Action Pin Circuit
      9 LMP07 (BU/WH)
      G08034314
      1 LMP07 (BU/WH)
      8 VMP21 (WH/BN)
      G08034315
      2 VMP21 (WH/BN)
      12 RMP07 (GN/WH)
      G08034316
      3 RMP07 (GN/WH)

    Are the resistances less than 3 ohms? 

    1. Yes: GO to .
    2. No: REPAIR the circuit in question.
  4. CHECK THE ACTIVE PARK ASSIST SENSOR CIRCUITRY FOR SHORTS TO GROUND
    1. For DTC B129C:14, measure:
      LH Active Park Assist Sensor Ground
      G08034318
      G08034317
      C1607 Ground
      Pin Circuit Measurement / Action Pin Circuit
      2 VMP20 (GY/OG)
      G08034319
      - Ground
    2. For DTC B129D:14, measure:
      RH Active Park Assist Sensor Ground
      G08034320
      G08034321
      C1608 Ground
      Pin Circuit Measurement / Action Pin Circuit
      2 VMP21 (WH/BN)
      G08034322
      - Ground

    Are the resistances greater than 10, 000 ohms? 

    1. Yes: If both of the active park assist sensors recorded DTCs  , GO to . Otherwise, INSTALL a new sensor for the one in question. REFER to Active Park Assist Sensor .
    2. No: REPAIR the circuit in question.
  5. CHECK FOR CORRECT PAM OPERATION
    1. Disconnect and inspect the PAM connector.
    2. 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
    3. Reconnect the PAM connector. Make sure it seats and latches correctly.
    4. Operate the system and determine if the concern is still present.

    Is the concern still present? 

    1. Yes: CHECK OASIS  for any applicable TSBs  . If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs  address this concern, INSTALL a new PAM. REFER to PARKING AID MODULE (PAM) .
    2. No: The system is operating correctly at this time. Concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
