ECD SYSTEM (w/ EGR Cooler), Diagnostic DTC:P0560

DTC Code DTC Name
P0560 System Voltage

DESCRIPTION

While the ignition switch is OFF, battery voltage is supplied to terminal BATT of the ECM for storing DTCs and fuel injection feedback learning values.

DTC No. DTC Detection Condition Trouble Area
P0560

Condition (a) or (b) continues:

(a) Significant decrease in battery voltage

(b) Open in back-up power source circuit (1 trip detection logic)

  • Open in back-up power source circuit

  • Low battery voltage

  • ECM

Tech Tips

If DTC P0560 appears, the ECM does not store other DTCs.

INSPECTION PROCEDURE

Note

If the ECM is replaced, the new ECM needs registration Click here and initialization Click here.

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, and other data from the time the malfunction occurred.

PROCEDURE


  1. CHECK FUSE (EFI FUSE)


    1. A01DXVCE10

      Remove the EFI fuse from the engine room junction block.

    2. Measure the resistance of the EFI fuse.

      Standard resistance
      Below 1 Ω

    NG

    CHECK FOR SHORTS IN ALL HARNESSES AND CONNECTORS CONNECTED TO FUSE AND REPLACE FUSE

    OK

  2. CHECK ECM (BATT VOLTAGE)


    1. A01DXHUE06

      Measure the voltage of the E7 and E6 ECM connectors.

      Standard voltage
      Tester Connection Specified condition
      E6-2 (BATT) - E7-7 (E1) 11 to 14 V

    NG

    CHECK HARNESS AND CONNECTOR (ECM - EFI FUSE, EFI FUSE - BATTERY) Click here

    OK

    REPLACE ECM

  3. CHECK HARNESS AND CONNECTOR (ECM - EFI FUSE, EFI FUSE - BATTERY)


    1. A01DWRWE01

      Check the harness and the connector between the EFI fuse and ECM.


      1. Disconnect the E6 ECM connector.

      2. Remove the EFI fuse from the engine room junction block.

      3. Measure the resistance.

        Standard resistance (Check for open)
        Tester Connection Specified Condition
        E6-2 (BATT) - 2 (EFI fuse) Below 1 Ω
        Standard resistance (Check for short)
        Tester Connection Specified Condition
        E6-2 (BATT) or 2 (EFI fuse) - Body ground 10 kΩ or higher

    2. Check the harness and the connector between the EFI fuse and battery.


      1. Remove the EFI fuse from the engine room junction block.

      2. Disconnect the positive battery terminal.

      3. Measure the resistance.

        Standard resistance (Check for open)
        Tester Connection Specified Condition
        Battery positive terminal - EFI fuse (1) Below 1 Ω
        Standard resistance (Check for short)
        Tester Connection Specified Condition
        Battery positive terminal or EFI fuse (1) - Body ground 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  4. CHECK BATTERY


    1. Check that the battery is not depleted.

      OK
      Battery is not depleted

    NG

    REPLACE BATTERY

    OK

    CHECK AND REPLACE ENGINE ROOM JUNCTION BLOCK
