DTC P0560 System Voltage


DESCRIPTION

The battery supplies electricity to the ECM even when the ignition switch is in the off position. 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 will illuminate the MIL and sets the DTC.

INSPECTION PROCEDURE

HINT:
Read freeze frame data using the intelligent tester. Freeze frame data records the engine conditions when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was running or stopped, 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 FUSE (EFI MAIN FUSE)
Toyota Rav4. Aca30, 33, 38 Gsa33 Zsa30, 35.1Az-Fe Engine Control System.Sfi System. Dtc P0560 System Voltage

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

  1. Measure the resistance of the EFI MAIN fuse.

    Standard resistance:
    Below 1 Ω

  1. Reinstall the EFI MAIN fuse.

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

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

    2. Disconnect the A12 ECM connector.

    3. Measure the resistance.

      Standard resistance (Check for open):
      Tester Connection
      		Specified Condition
      EFI MAIN fuse (2) - BATT (A12-20)
      		Below 1 Ω
      Standard resistance (Check for short):
      Tester Connection
      		Specified Condition
      EFI MAIN fuse (2) or BATT (A12-20) - Body ground
      		10 kΩ or higher

    4. Reconnect the ECM connector.

    5. Reinstall the EFI MAIN fuse.

  1. Check the harness and the connector between the EFI MAIN fuse and battery.

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

    2. Disconnect the positive battery terminal.

    3. Measure the resistance.

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

    4. Reconnect the positive battery terminal.

    5. Reinstall the EFI MAIN fuse.

3.INSPECT BATTERY

  1. Check that the battery is not depleted.

OK:
Battery is not depleted.


NG
REPLACE BATTERY
OK


4.CHECK BATTERY TERMINAL

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

    OK:
    Battery terminals are not loose or corroded


NG
REPAIR OR REPLACE BATTERY TERMINAL
OK


5.CHECK WHETHER DTC OUTPUT RECURS

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch on (IG) and turn the tester ON.

  1. Clear DTCs (RAV4_ACA30 RM000000PDK0AHX.html).

  1. Turn the ignition switch off and turn the tester OFF.

  1. Start the engine and turn the tester ON.

  1. Select the following menu items: Powertrain / Engine and ECT/ DTC.

  1. Read DTCs.
