Pinpoint Test P: Keep Alive Power (KAPWR)

  1. Normal Operation and Fault Conditions 

    Refer to the DTC Fault Trigger Conditions.

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    PCM P2610:00 ECM/PCM Engine Off Timer Performance: No Sub Type Information Sets when the PCM detects the difference between the engine off time and the central processing unit (CPU) time exceeds a calibrated limit for a calibrated amount of time. This DTC may set with other DTCs. Check for all other Diagnostic Trouble Codes (DTCs) and diagnose those first. If DTC P2610 sets after a module programming, disregard this DTC. Clear the DTCs and repeat the PCM self-test.

    Possible Sources 

    • Battery terminal condition
    • PCM circuitry concern
    • PCM

  2. P1 CHECK FOR DIAGNOSTIC TROUBLE CODES (DTCS)

    NOTE: The DTC P2610 may set after a PCM reprogramming. If this DTC is retrieved after a PCM reprogramming, disregard this DTC.

    • Carry out a visual inspection.

    • Record the DTCs.

    • Record the freeze frame data.

    • Clear the PCM DTCs. Carry out the PCM self-test.

    Is DTC P2610 present? 

    Yes  GO to  P2
    No  Unable to duplicate the condition. CHECK for a loose connection, and damaged or corroded pins. WIGGLE the harness attempting to recreate the concern. REPAIR as necessary. REFER to QT: POWERTRAIN CONTROL MODULE (PCM) QUICK TEST , if a driveability concern exists. Clear the PCM DTCs. REPEAT the self-test.

  3. P2 CHECK THE ENGINE OFF TIMER

    NOTE: Turning the ignition ON then OFF without an engine start for the purpose of checking the engine coolant temperature does not affect the test results.

    • Start the engine.

    • Allow the engine to stabilize at the correct operating temperature.

    • Ignition OFF.

    • Ignition ON.

    • Clear the PCM DTCs.

    • Ignition OFF.

    • Allow the engine to cold soak long enough for the engine coolant temperature to drop at least 16.7 deg. C (30 deg. F).

    • Ignition ON.

      • Carry out the PCM self-test.

    Is DTC P2610 present? 

    Yes  GO to  P3
    No  Unable to duplicate the condition. REFER to QT: POWERTRAIN CONTROL MODULE (PCM) QUICK TEST , to continue diagnosis.

  4. P3 CHECK FOR ANY BODY CONTROL MODULE (BCM) DTCS

    • Carry out the BCM self-test.

    Are any DTCs present? 

    Yes  REFER to: Body Control Module (BCM)
    No  GO to  P4

  5. P4 CHECK FOR CORRECT PCM OPERATION

    • Disconnect All the PCM electrical connectors.

    • Visually inspect for:

      • pushed out pins

      • corrosion

    • Connect All the PCM connectors and make sure they seat correctly.

      • Carry out the PCM self-test.

    Is the concern still present? 

    Yes  INSTALL a new PCM. REFER to Powertrain Control Module (PCM)  and PROGRAMMING THE VID BLOCK FOR A REPLACEMENT PCM
    No  The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
