СИСТЕМА SFI, Diagnostic DTC:P0560

DTC Code DTC Name
P0560 System Voltage

DESCRIPTION

The battery supplies electricity to the ECM even when the engine switch is off. This power allows the ECM to store data such as DTC history, freeze frame data and fuel trim values. If the battery voltage falls below a minimum level, the memory is cleared and the ECM determines that there is a malfunction in the power supply circuit. When the engine is next started, the ECM illuminates the MIL and stores the DTC.

DTC Code DTC Detection Condition Trouble Area
P0560 An open in the ECM back up power source circuit (1 trip detection logic).

  • Open in back up power source circuit

  • Battery

  • Battery terminals

  • EFI MAIN fuse

  • ECM

Tech Tips

If DTC P0560 is stored, the ECM does not store other DTCs or the data stored in the ECM is partly cleared.

INSPECTION PROCEDURE

Note

Inspect the fuses for circuits related to this system before performing the following inspection procedure.

Tech Tips

Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE


  1. INSPECT BATTERY


    1. Check that the battery is not depleted Click here.

      OK
      Battery is not depleted.

    NG

    REPLACE BATTERY

    OK

  2. CHECK BATTERY TERMINAL


    1. Check that the battery terminals are not loose or corroded.

      OK
      Battery terminals are not loose or corroded.

    NG

    REPAIR BATTERY TERMINAL

    OK

  3. INSPECT ECM (BATT VOLTAGE)

    A015BNWE15

    1. Disconnect the A38 ECM connector.

    2. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Condition Specified Condition
      A38-1 (BATT) - Body ground Always 11 to 14 V

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  4. CHECK WHETHER DTC OUTPUT RECURS


    1. Connect the intelligent tester to the DLC3.

    2. Turn the engine switch on (IG) and turn the tester on.

    3. Clear DTCs Click here.

    4. Turn the engine switch off and turn the tester off.

    5. Start the engine and turn the tester on.

    6. Enter the following menus: Powertrain / Engine and ECT / DTC.

    7. Read DTCs.

      Result
      Result Proceed to
      P0560 is output A
      No DTC is output B
