PINPOINT TEST C: DTCs B1B44:12, B1B46:12, B1B48:12 AND B1B50:12

WARNING: This page is about a different car, the 2013 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
  1. C1 RETRIEVE THE DTCs FROM THE PAM SELF-TEST 
    • Check the PAM DTCs from the self-test.
    • Are multiple DTCs recorded? 
    • Yes  : GO to C2.
    • No  : For DTCs B1B44:12, B1B46:12, B1B48:12 and B1B50:12, GO to  C3.

      For all other DTCs, REFER to DTC CHARTS .

  2. C2 CHECK THE BUMPER WIRING HARNESS 
    • Inspect the bumper wiring harness for opens, shorts, grounds, or corrosion.
    • Is the bumper wiring harness OK? 
    • Yes  : GO to C3.
    • No  : REPAIR or INSTALL a new bumper wiring harness. CLEAR the DTCs. REPEAT the self-test.
  3. C3 CHECK THE SENSOR CIRCUITRY FOR SHORTS TO VOLTAGE 
    • Ignition OFF.
    • Disconnect: Suspect Parking Aid Sensor C4009, C4010, C4011 or C4012.
    • Disconnect: PAM C4014.
    • Ignition ON.
    • Measure the voltage between the suspect parking aid sensor, harness side and ground as follows:
      DTC Rear Sensor Connector-Pin Circuit
      B1B44:12 RH outer C4011-2 VMP17 (YE/OG)
      B1B46:12 RH inner C4012-2 VMP16 (YE/GY)
      B1B48:12 LH outer C4009-2 VMP15 (YE/GN)
      B1B50:12 LH inner C4010-2 VMP14 (WH/OG)

    • Is any voltage present? 
    • Yes  : REPAIR the circuit in question. CLEAR the DTCs. TEST the system for normal operation.
    • No  : GO to C4.
  4. C4 CHECK THE PARKING AID SENSOR CIRCUITRY FOR A SHORT TOGETHER 
    • Measure the resistance between the suspect parking aid sensor pins, harness side as follows:
      DTC Parking Aid Sensor Connector-Pin/Circuit Connector-Pin/Circuit
      B1B44:12 RH outer C4011-2 VMP17 (YE/OG) C4011-1 LMP07 (BU/WH)
      B1B46:12 RH inner C4012-2 VMP16 (YE/GY) C4012-1 LMP07 (BU/WH)
      B1B48:12 LH outer C4009-2 VMP15 (YE/GN) C4009-1 LMP07 (BU/WH)
      B1B50:12 LH inner C4010-2 VMP14 (WH/OG) C4010-1 LMP07 (BU/WH)

    • Is the resistance greater than 10, 000 ohms? 
    • Yes  : If all sensor DTCs are set, GO to C5.

      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 circuits in question. CLEAR the DTCs. TEST the system for normal operation.
  5. C5 CHECK FOR CORRECT PAM OPERATION 
    • Connect: All Disconnected Connectors.
    • 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.
