ECD SYSTEM, 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

PROCEDURE


  1. INSPECT FUSE (E/G FUSE)


    1. A01CJH0E01

      Remove the E/G fuse from the No. 2 relay block.

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

      Standard resistance
      Tester Connection Condition Specified Condition
      1 - 2 Always Below 1 Ω

    3. Reinstall the E/G fuse.


    NG

    REPLACE FUSE (E/G FUSE)

    OK

  2. CHECK HARNESS AND CONNECTOR (ECM - BATTERY)


    1. A01CHBUE01

      Disconnect the negative battery terminal.

    2. Disconnect the positive battery terminal.

    3. Disconnect the ECM connector.

    4. Measure the resistance according to the value(s) in the table below.

      Standard resistance
      Check for open
      Tester Connection Condition Specified Condition
      E24-2 (BATT) - Positive battery terminal Always Below 1 Ω
      Check for short
      Tester Connection Condition Specified Condition
      E24-2 (BATT) or Positive battery terminal - Body ground Always 10 kΩ or higher

    5. Reconnect the ECM connector.

    6. Reconnect the positive battery terminal.

    7. Reconnect the negative battery terminal.


    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR (ECM - BATTERY)

    OK

  3. READ VALUE USING INTELLIGENT TESTER (BATTERY VOLTAGE)


    1. Replace the normal DLC3 cable (12 V specification) for the intelligent tester with the 24 V DLC3 cable.

      Note

      Be sure to use the 24 V DLC3 cable when connecting the intelligent tester to the DLC3. Using the normal DLC3 cable (12 V specification) will cause damage to the tester.

    2. Connect the intelligent tester to the DLC3.

    3. Turn the ignition switch to the ON position.

    4. Turn the tester on.

    5. Enter the following menu items: Powertrain / Engine and ECT / Data List / Battery Voltage.

    6. Read the values.

      Standard voltage
      18 to 27 V

    NG

    REPLACE BATTERY

    OK

    REPLACE ECM
