Pinpoint Test E: DTC (Diagnostic Trouble Code) B1B44:96, B1B46:96, B1B48:96, B1B50:96

  1. E1 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 B1B44:96, B1B46:96, B1B48:96 or B1B50:96 recorded? 

    Yes  For all other Diagnostic Trouble Codes (DTCs) REFER to the DTC Chart: PAM .
    No  GO to  E2

  2. E2 CHECK THE PARKING AID SENSOR DISTANCE PARAMETER IDENTIFICATIONS (PIDS) WITH NO OBJECTS BEHIND THE VEHICLE

    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.

    • Make sure the suspect parking aid sensor(s) is flush-mounted in the bezel.

    • Ignition ON.

    • Using a diagnostic scan tool, monitor the PAM parking aid sensor distance Parameter Identifications (PIDs) (LRI_DIST, LRO_DIST, RRI_DIST, RRO_DIST). The PID reads 2, 540 mm (100 in) on a correctly functioning sensor.

    Does the PID read 2, 540 mm (100 in)? 

    Yes  GO to  E3
    No  GO to  E4

  3. E3 CHECK THE PARKING AID SENSOR DISTANCE PARAMETER IDENTIFICATIONS (PIDS) WITH A TEST OBJECT BEHIND THE VEHICLE

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

    • Using a diagnostic scan tool, monitor the PAM parking aid sensor distance Parameter Identifications (PIDs) (LRI_DIST, LRO_DIST, RRI_DIST, RRO_DIST).

    • While monitoring the Parameter Identifications (PIDs), move a test object into and out of the detection zone behind each sensor. For an example of a test object, REFER to: Azimuth System Check 

    Does the PID approximately match the distance from the test object to the rear bumper of the vehicle? 

    Yes  GO to  E5
    No  GO to  E4

  4. E4 CHECK THE PARKING AID SENSORS

    • Ignition OFF.

    • Ignition ON.

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

    • Check the PAM Diagnostic Trouble Codes (DTCs).

    Is the concern still present? 

    Yes  GO to  E5
    No  INSTALL a new rear parking aid sensor. REFER to: Rear Parking Aid Sensor 

  5. E5 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

    • Ignition OFF.

    • Disconnect and inspect all BCM connectors 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 BCM connectors 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 Technical Service Bulletins (TSBs) address this concern, INSTALL a new BCM. Refer to BODY CONTROL MODULE (BCM) .
    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.
