WARNING: This page is about a different car, the 2016 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.

  1. I1 CHECK THE DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE PAM (PARKING ASSIST CONTROL MODULE) SELF-TEST

    • Using a diagnostic scan tool, perform the PAM self-test.
    • Check the PAM Diagnostic Trouble Codes (DTCs) from the self-test.

    Are parking aid Diagnostic Trouble Codes (DTCs) other than B1B36:96, B1B38:96, B1B40:96 or B1B42:96 recorded? 

    Yes  DIAGNOSE other Diagnostic Trouble Codes (DTCs) first. REFER to Diagnostic Trouble Code (DTC) Chart: Parking Aid Module 
    No  GO to  I2

  2. I2 CHECK THE PARKING AID SENSOR OPERATION

    NOTE: Make sure the area around the vehicle is clear of anything that can activate the parking aid system.

    • Clean the rear bumper and sensors with high-pressure water.

    Does the parking aid system pass the azimuth system check? 

    Yes  The system is operating correctly at this time. The concern may have been caused by a dirty or blocked parking aid sensor.
    No  GO to  I3

  3. I3 CHECK THE PARKING AID SENSOR DISTANCE PARAMETER IDENTIFICATIONS (PIDS)

    • Make sure the suspect parking aid sensor is flush-mounted in the bezel.
    • Ignition ON.
    • Using a diagnostic scan tool, monitor the PAM Parameter Identifications (PIDs).
    • Monitor and record the parking aid sensor distance Parameter Identifications (PIDs) (LFI_DIST, LFO_DIST, RFI_DIST, RFO_DIST) while moving a test object into and out of the azimuth field for each of the sensors. For an example of an appropriate test object, REFER to: Azimuth System Check 

    Do the PID distances approximately match the distance from the vehicle to the test object? 

    Yes  GO to  I5
    No  GO to  I4

  4. I4 CHECK THE PARKING AID SENSORS

    • Ignition OFF.
    • Ignition ON.
    • Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs). Repeat the self-test. Operate the system and verify the concern is still present.

    Is the concern still present? 

    Yes  GO to  I5
    No  The cause of the concern was an inoperative parking aid sensor. The system is now operating correctly.

  5. I5 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) - 4-Door  REFER to: Parking Assist Control Module (PAM) - 5-Door 
    No  The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
