Pinpoint Test B: P0230:12, P0230:14

  1. B1 CHECK THE FUEL PUMP RELAY

    • Ignition OFF.

    • Swap the fuel pump relay with a known good relay.

    • Ignition ON.

    • Using a diagnostic scan tool, clear the BCM Diagnostic Trouble Codes (DTCs).

    • Perform the BCM self-test.

    Is DTC P0230:12 or P0230:14 still present? 

    Yes  For DTC P0230:12, GO to  B2 For DTC P0230:14, GO to  B3
    No  REPLACE the fuel pump relay.

  2. B2 CHECK FOR A SHORT TO VOLTAGE ON THE FUEL PUMP RELAY CONTROL CIRCUIT

    • Ignition OFF.

    • Remove fuel pump relay.

    • Disconnect BCM C2280E.

    • Ignition ON.

    • Measure:
      Positive Lead Measurement / Action Negative Lead

      		 Ground

    Is any voltage present? 

    Yes  REPAIR the circuit.
    No  GO to  B4

  3. B3 CHECK FOR VOLTAGE AT THE BCM (BODY CONTROL MODULE)

    • Ignition OFF.

    • Disconnect BCM C2280E.

    • Using the Terminal Release Kit, release and temporarily remove BCM C2280E-24.

    • Connect BCM C2280E.

    • Ignition ON.

    • Measure the de-pined circuit:
      Positive Lead Measurement / Action Negative Lead
      C2280E-24

      		 Ground

    Is the voltage greater than 11 volts? 

    Yes  GO to  B4
    No  VERIFY BJB fuse is OK. If OK, REPAIR the circuit. If not OK, REFER to the OEM ELECTRICAL WIRING DIAGRAM INTRODUCTION to identify the possible causes for the short circuit.

  4. B4 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

    • Ignition OFF.

    • Disconnect and inspect the BCM electrical connection(s) (harness side connectors and module terminals).

    • 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 electrical connection(s). 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.
