PINPOINT TEST B: DTC B1B44:14, B1B46:14, B1B48:14 Or B1B50:14

NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
  1. B1 CHECK THE RECORDED DTCs FROM BOTH THE CONTINUOUS AND ON-DEMAND PAM SELF-TESTS 
    • Check the recorded PAM DTCs from the continuous and on-demand self-tests.
    • Are multiple DTCs recorded? 
    • Yes  : GO to B2.
    • No  : For DTC B1B44:14, B1B46:14, B1B48:14 or B1B50:14, GO to  B3.

      For all others, REFER to DTC CHARTS  .

  2. B2 CHECK THE BUMPER WIRING HARNESS 
    • Inspect the bumper wiring harness for opens, shorts, or corrosion.
    • Is the bumper wiring harness OK? 
    • Yes  : GO to B3.
    • No  : REPAIR or INSTALL a new bumper wiring harness. CLEAR the DTCs. REPEAT the self-test.
  3. B3 CHECK THE SENSOR CIRCUITRY FOR OPENS 
    • Ignition OFF.
    • Disconnect: Suspect Parking Aid Sensor C4009, C4010, C4011 and C4012.
    • Disconnect: PAM C4014.
    • Measure the resistance between the PAM C4014, harness side and the suspect parking aid sensor, harness side as follows:
      DTC Sensor PAM Connector - Pin Sensor Connector - Pin Circuit
      B1B44:14 RH outer C4014-9 C4011-1 LMP07 (BU/WH)
      B1B44:14 RH outer C4014-16 C4011-2 VMP17 (YE/OG)
      B1B44:14 RH outer C4014-12 C4011-3 RMP07 (GN/WH)
      B1B46:14 RH inner C4014-9 C4012-1 LMP07 (BU/WH)
      B1B46:14 RH inner C4014-13 C4012-2 VMP16 (YE/GY)
      B1B46:14 RH inner C4014-12 C4012-3 RMP07 (GN/WH)
      B1B48:14 LH outer C4014-9 C4009-1 LMP07 (BU/WH)
      B1B48:14 LH outer C4014-15 C4009-2 VMP15 (YE/GN)
      B1B48:14 LH outer C4014-12 C4009-3 RMP07 (GN/WH)
      B1B50:14 LH inner C4014-9 C4010-1 LMP07 (BU/WH)
      B1B50:14 LH inner C4014-14 C4010-2 VMP14 (WH/OG)
      B1B50:14 LH inner C4014-12 C4010-3 RMP07 (GN/WH)

    • Are the resistances less than 5 ohms? 
    • Yes  : GO to B4.
    • No  : REPAIR the circuit in question. CLEAR the DTCs. TEST the system for normal operation.
  4. B4 CHECK THE SENSOR CIRCUITRY FOR SHORTS TO GROUND 
    • Measure the resistance between the suspect parking aid sensor, harness side and ground as follows:
      DTC Sensor Sensor Connector-Pin Circuit
      B1B44:14 RH outer C4011-2 VMP17 (YE/OG)
      B1B46:14 RH inner C4012-2 VMP16 (YE/GY)
      B1B48:14 LH outer C4009-2 VMP15 (YE/GN)
      B1B50:14 LH inner C4010-2 VMP14 (WH/OG)

    • Is the resistance greater than 10, 000 ohms? 
    • Yes  : If all of the parking aid sensors recorded DTCs, GO to B5.

      If one or more parking aid sensor(s) recorded DTCs, INSTALL a new sensor(s) for the one in question. REFER to PARKING AID SENSOR  . CLEAR the DTCs. TEST the system for normal operation.

    • No  : REPAIR the circuit in question. CLEAR the DTCs. TEST the system for normal operation.
  5. B5 CHECK FOR CORRECT PAM OPERATION 
    • Disconnect the PAM connector.
    • Check for:
      • corrosion
      • damaged pins
      • pushed-out pins
    • Connect the PAM connector and make sure it seats correctly.
    • Operate the system and determine if the concern is still present.
    • Is the concern still present? 
    • Yes  : INSTALL a new PAM. REFER to PARKING AID MODULE (PAM)  . TEST the system for normal operation.
    • No  : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.
