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

    Refer to Parking Aid for schematic and connector information.

    Normal Operation and Fault Conditions 

    The PAM supplies voltage and ground to the rear parking aid sensors and monitors the sensor signal return circuits when the ignition is on.

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition

    PAM B1B46:12 Right Rear Inner Sensor: Circuit Short To Battery A continuous and on-demand DTC that sets when the right rear inner parking aid sensor signal circuit is shorted to battery voltage.
    PAM B1B48:12 Left Rear Outer Sensor: Circuit Short To Battery A continuous and on-demand DTC that sets when the left rear outer parking aid sensor signal circuit is shorted to battery voltage.
    PAM B1B50:12 Left Rear Inner Sensor: Circuit Short To Battery A continuous and on-demand DTC that sets when the left rear inner parking aid sensor signal circuit is shorted to battery voltage.

    Possible Sources 

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

  2. D1 RETRIEVE THE DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE PAM (PARKING ASSIST CONTROL MODULE) SELF-TEST

    • Ignition ON.

    • Using a diagnostic scan tool, perform the PAM self-test.

    Yes  GO to  D2
    No  For Diagnostic Trouble Codes (DTCs) B1B44:12, B1B46:12, B1B48:12 or B1B50:12, GO to  D3 For all other Diagnostic Trouble Codes (DTCs), REFER to PAM DTC Chart .

  3. D2 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  D3
    No  REPAIR or INSTALL a new rear bumper wiring harness.

  4. D3 CHECK THE REAR PARKING AID SENSOR SIGNAL CIRCUIT(S) FOR A SHORT TO VOLTAGE

    • Ignition OFF.

    • Disconnect suspect parking aid sensor(s) C4009, C4010, C4011 and/or C4012.

    • Disconnect PAM C4014C.

    • Ignition ON.

    • Measure:

    Is the resistance greater than 10, 000 ohms? 

    Yes  If all the parking aid sensors recorded Diagnostic Trouble Codes (DTCs), GO to  D5 If one or more (but not all) parking aid sensor(s) recorded Diagnostic Trouble Codes (DTCs), INSTALL a new sensor for the one(s) in question. REFER to: Rear Inner Parking Aid Sensor . REFER to: Rear Outer Parking Aid Sensor . If the concern is still present after sensor replacement, GO to  D5
    No  REPAIR the circuits in question.

  6. D5 CHECK FOR CORRECT PAM (PARKING ASSIST CONTROL MODULE) OPERATION

    • Ignition OFF.

    • Disconnect and inspect the PAM 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 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 TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new PAM. REFER to: Parking Assist Control Module (PAM) .
    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.
