Pinpoint Test N : B1112:11

  1. Refer to Parking Aid for schematic and connector information.

    Normal Operation and Fault Conditions 

    The PAM receives voltage through BCM fuse 4 (5A) when the ignition is on.

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    BCM B1112:11 Park Aid Ignition: Circuit Short To Ground Sets in continuous memory and on-demand in the BCM when a short to ground is detected on the PAM voltage supply circuit.

    Possible Sources 

    • Wiring, terminals or connectors
    • PAM
    • BCM

  2. N1 PERFORM A NETWORK TEST

    • Ignition ON.

    • Using a diagnostic scan tool, perform a network test.

    Do all modules pass the network test? 

    Yes  GO to  N2
    No  REFER to: Communications Network .

  3. N2 CHECK THE BCM (BODY CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS) WITH THE PAM (PARKING ASSIST CONTROL MODULE) DISCONNECTED

    • Ignition OFF.

    • Disconnect PAM C4014A.

    • Ignition ON.

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

    Is DTC B1112:11 still present? 

    Yes  GO to  N3
    No  GO to  N4

  4. N3 CHECK THE VOLTAGE SUPPLY CIRCUIT FOR A SHORT TO GROUND

    • Ignition OFF.

    • Disconnect BCM C2280D.

    • Measure:
      Positive Lead Measurement / Action Negative Lead

      		 Ground

    Is the resistance greater than 10, 000 ohms? 

    Yes  GO to  N5
    No  REPAIR the circuit.

  5. N4 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.

  6. N5 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

    • Ignition OFF.

    • Disconnect and inspect the BCM 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. 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 BCM. REFER to: Body Control Module (BCM) .
    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.
