Pinpoint Test B

NOTE: Before disconnecting the PAM or the sensors, verify that the connectors are properly seated and latched.
  1. RETRIEVE THE DTCs  FROM THE PAM SELF-TEST
    1. Check the PAM DTCs  from the self-test.

    Are multiple DTCs recorded? 

    • Yes: GO to 2  .
    • No: GO to  3.
  2. CHECK THE CONNECTORS FOR CORRECT LATCHING AND THE BUMPER WIRING HARNESS FOR DAMAGE
    1. Inspect the PAM and sensor connectors for correct latching by pulling on the latched connector.
    2. Inspect the bumper wiring harness for opens, shorts or corrosion.

    Are the connectors correctly latched and the bumper wiring harness OK? 

    • Yes: GO to 3  .
    • No: Correctly LATCH the connectors or REPAIR or INSTALL a new bumper wiring harness.
  3. CHECK THE SENSOR CIRCUITRY FOR SHORTS TO GROUND
    1. Ignition OFF.
    2. Disconnect: Suspect Parking Aid Sensor.
    3. Disconnect: PAM.
    4. Measure:
      Suspect Parking Aid Sensor Ground
      G08034187
      G08034188
      Parking Aid Sensor Ground
      DTC Connector-Pin / Circuit Measurement / Action Pin Circuit
      B1B44:14
      (right outer)      		 C4011-2 / VMP17 (YE/OG)
      G08034189
      		 - Ground
      B1B46:14
      (right inner)      		 C4012-2 / VMP16 (YE/GY) - Ground
      B1B48:14
      (left outer)      		 C4009-2 / VMP15 (YE/GN) - Ground
      B1B50:14
      (left inner)      		 C4010-2 / VMP14 (WH/OG) - Ground

    Are the resistances greater than 10, 000 ohms? 

    • Yes: GO to 4  .
    • No: REPAIR the circuit(s) in question.
  4. CHECK THE SENSOR CIRCUITRY FOR OPENS
    1. Measure:
      PAM Suspect Parking Aid Sensor
      G08034190
      G08034191
      C3267 Parking Aid Sensor
      DTC Pin / Circuit Measurement / Action Connector-Pin Circuit
      B1B44:14
      (right outer)      		 9 / LMP07 (BU/WH)
      G08034192
      		 C4011-1 LMP07 (BU/WH)
      16 / VMP17 (YE/OG) C4011-2 VMP17 (YE/OG)
      12 / RMP07 (GN/WH) C4011-3 RMP07 (GN/WH)
      B1B46:14
      (right inner)      		 9 / LMP07 (BU/WH) C4012-1 LMP07 (BU/WH)
      13 / VMP16 (YE/GY) C4012-2 VMP16 (YE/GY)
      12 / RMP07 (GN/WH) C4012-3 RMP07 (GN/WH)
      B1B48:14
      (left outer)      		 9 / LMP07 (BU/WH) C4009-1 LMP07 (BU/WH)
      15 / VMP15 (YE/GN) C4009-2 VMP15 (YE/GN)
      12 / RMP07 (GN/WH) C4009-3 RMP07 (GN/WH)
      B1B50:14
      (left inner)      		 9 / LMP07 (BU/WH) C4010-1 LMP07 (BU/WH)
      14 / VMP14 (WH/OG) C4010-2 VMP14 (WH/OG)
      12 / RMP07 (GN/WH) C4010-3 RMP07 (GN/WH)

    Are the resistances less than 3 ohms? 

    • Yes: If all of the parking aid sensors recorded DTCs  , GO to 5  .

      If one or more (but not all) parking aid sensor(s) recorded DTCs  , INSTALL a new sensor(s) for the sensor(s) in question. REFER to Parking Aid Sensor .

    • No: REPAIR the circuit(s) 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? 

    • 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) .
    • No: The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
