Pinpoint Test C : B1B58: 11

  1. NOTE: Before disconnecting the PAM or any of the parking aid sensors, verify the connectors are properly seated and latched.

    Normal Operation and Fault Conditions 

    The PAM supplies voltage to the rear parking aid sensors via a common circuit.

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    PAM B1B58: 11 Rear Sensors Power Circuit: Circuit Short To Ground A continuous and on-demand DTC that sets in the PAM when the rear sensor voltage supply circuit is shorted to ground or to the signal return circuit.

    Possible Sources 

    • Wiring, terminals or connectors
    • Rear Parking aid sensor
    • PAM

  2. C1 CHECK THE REAR BUMPER WIRING HARNESS

    • Ignition OFF.

    • Inspect the rear bumper wiring harness for opens, shorts, grounds, or corrosion.

    Is the rear bumper wiring harness OK? 

    Yes  GO to  C2
    No  REPAIR or INSTALL a new rear bumper wiring harness.

  3. C2 CHECK THE LHR (LEFT-HAND REAR) OUTER PARKING AID SENSOR FOR AN INTERNAL SHORT

    • Disconnect: LHR Outer Parking Aid Sensor C4011.

    • Ignition ON.

    • Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs) and repeat the self-test.

    Is DTC B1B58: 11 still present? 

    Yes  GO to  C3
    No  INSTALL a new LHR outer parking aid sensor.

  4. C3 CHECK THE LHR (LEFT-HAND REAR) INNER PARKING AID SENSOR FOR AN INTERNAL SHORT

    • Ignition OFF.

    • Disconnect: LHR Inner Parking Aid Sensor C4012.

    • Ignition ON.

    • Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs) and repeat the self-test.

    Is DTC B1B58: 11 still present? 

    Yes  GO to  C4
    No  INSTALL a new LHR inner parking aid sensor.

  5. C4 CHECK THE RHR (RIGHT-HAND REAR) OUTER PARKING AID SENSOR FOR AN INTERNAL SHORT

    • Ignition OFF.

    • Disconnect: RHR Outer Parking Aid Sensor C4009.

    • Ignition ON.

    • Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs) and repeat the self-test.

    Is DTC B1B58: 11 still present? 

    Yes  GO to  C5
    No  INSTALL a new RHR outer parking aid sensor.

  6. C5 CHECK THE RHR (RIGHT-HAND REAR) INNER PARKING AID SENSOR FOR AN INTERNAL SHORT

    • Ignition OFF.

    • Disconnect: RHR Inner Parking Aid Sensor C4010.

    • Ignition ON.

    • Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs) and repeat the self-test.

    Is DTC B1B58: 11 still present? 

    Yes  GO to  C6
    No  INSTALL a new RHR inner parking aid sensor.

  7. C6 CHECK THE PARKING AID SENSOR VOLTAGE SUPPLY CIRCUIT FOR A SHORT TO GROUND

    • Ignition OFF.

    • Disconnect: PAM C4014A.

    • Measure:
      Positive Lead Measurement / Action Negative Lead

      		 Ground

    Is the resistance greater than 10, 000 ohms? 

    Yes  GO to  C7
    No  REPAIR the circuit.

  8. C7 CHECK THE PARKING AID SENSOR VOLTAGE SUPPLY CIRCUIT AND GROUND CIRCUIT FOR A SHORT TOGETHER

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C4014A-3
      GFD328095Courtesy of FORD MOTOR COMPANY
      		 C4014A-10

    Is the resistance greater than 10, 000 ohms? 

    Yes  GO to  C8
    No  REPAIR the circuits.

  9. C8 CHECK FOR CORRECT PAM (PARKING ASSIST CONTROL MODULE) OPERATION

    • Ignition OFF.

    • Disconnect and inspect all PAM and related in-line 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 PAM and related in-line 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 TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no TSB addresses this concern, INSTALL a new PAM. REFER to: Parking Assist Control Module (PAM) .
    No  The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
