Pinpoint Test C: B1305:01, B1305:15

  1. Refer to REMOTE KEYLESS ENTRY AND ALARM for schematic and connector information.

    Normal Operation and Fault Conditions 

    REFER to: Perimeter Anti-Theft Alarm - System Operation and Component Description .

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    BCM B1305:01 Hood Switch: General Electrical Failure Sets when the BCM detects an open from the hood ajar switch input during a self-test. This DTC also sets if the self-test is carried out with the hood open.
    BCM B1305:15 Hood Switch: Circuit Short To Battery Or Open Sets when the BCM detects a short to battery or open from the hood ajar switch input during a self-test.

    Possible Sources 

    • Wiring, terminals or connectors
    • Hood latch
    • BCM

    Visual Inspection and Pre-checks 

    • Inspect the hood latch for damage.

  2. NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

  3. C1 CHECK THE HOOD AJAR SWITCH

    • Disconnect: Hood Ajar Switch C127.

    • Ignition ON.

    • Connect:
      Positive Lead Measurement / Action Negative Lead
      C127-2

      		 C127-1

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

    Is DTC B1305:01 or B1305:15 still present? 

    Yes  REMOVE the fused jumper wire. GO to  C2
    No  REMOVE the fused jumper wire. INSTALL a new hood latch. REFER to: Hood Latch

  4. C2 CHECK THE HOOD AJAR SWITCH GROUND CIRCUIT FOR AN OPEN

    • Connect a fused jumper wire:
      Positive Lead Measurement / Action Negative Lead
      C127-2

      		 Ground

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

    Is DTC B1305:01 or B1305:15 still present? 

    Yes  REMOVE the fused jumper wire. GO to  C3
    No  REMOVE the fused jumper wire. REPAIR the circuit.

  5. C3 CHECK THE HOOD AJAR SWITCH FOR A SHORT TO VOLTAGE

    • Disconnect BCM C2280E.

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C127-2

      		 Ground

    Is any voltage present? 

    Yes  REPAIR the circuit in question.
    No  GO to  C4

  6. C4 CHECK THE HOOD AJAR SWITCH INPUT CIRCUIT FOR AN OPEN

    • Ignition OFF.

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C127-2
      GFD591140Courtesy of FORD MOTOR COMPANY
      		 C2280E-26

    Is the resistance less than 3 ohms? 

    Yes  GO to  C5
    No  REPAIR the circuit.

  7. C5 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

    • Disconnect and inspect all 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 service articles: TSB, GSB, SSM, or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles 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 module connections. ADDRESS the root cause of any connector or pin issues.
