DTC P0560 System Voltage


DESCRIPTION

The battery supplies electricity to the ECM even when the ignition 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 stored ECM data is cleared and the ECM determines that there is a malfunction in the power supply circuit. When the engine is next started, the ECM will illuminate the MIL and set the DTC.

INSPECTION PROCEDURE

NOTICE:
Inspect the fuses for circuits related to this system before performing the following inspection procedure.
HINT:
Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. 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.
1.CHECK HARNESS AND CONNECTOR (EFI NO. 1 FUSE - ECM)
  1. Disconnect the ECM connector.

  1. Remove the EFI No. 1 fuse from the engine room relay block.

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

    Standard Resistance (Check for Open):
    Tester Connection
    Condition
    Specified Condition
    2 (EFI No. 1 fuse) - A24-20 (BATT)
    Always
    Below 1 Ω
    Standard Resistance (Check for Short):
    Tester Connection
    Condition
    Specified Condition
    2 (EFI No. 1 fuse) or A24-20 (BATT) - Body ground
    Always
    10 kΩ or higher
  1. Reconnect the ECM connector.

  1. Reinstall the EFI fuse.

2.INSPECT BATTERY
  1. Check the battery voltage.

    Battery voltage:
    11 to 14 V


NG
REPLACE BATTERY
OK


3.CHECK BATTERY TERMINAL
  1. Check that the battery terminals are not loose or corroded.

    OK:
    Battery terminals are not loose or corroded.
