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

  • Voltage converter sub-assembly

  • ECM

Tech Tips

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

INSPECTION PROCEDURE

PROCEDURE


  1. CHECK ECM (BATT VOLTAGE)


    1. A01CHV2E02
      Text in Illustration
      *1

      Rear view of wire harness connector

      (to ECM)

      Disconnect the ECM connector.

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      E24-2 (BATT) - Body ground Always 11 to 14 V

    3. Reconnect the ECM connector.

  2. CHECK HARNESS AND CONNECTOR (ECM - VOLTAGE CONVERTER SUB-ASSEMBLY)


    1. Disconnect the voltage converter sub-assembly connector.

    2. Disconnect the ECM connector.

    3. 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) - D8-7 (OUTM) Always Below 1 Ω
      Standard Resistance (Check for Short)
      Tester Connection Condition Specified Condition
      E24-2 (BATT) or D8-7 (OUTM) - Body ground Always 10 kΩ or higher

    4. Reconnect the ECM connector.

    5. Reconnect the voltage converter sub-assembly connector.


    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR (ECM - VOLTAGE CONVERTER SUB-ASSEMBLY)

    OK

  3. INSPECT BATTERY


    1. Check that the battery is not depleted.

      OK
      Battery is not depleted.

    NG

    REPAIR OR REPLACE BATTERY

    OK
