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 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 illuminates the MIL and stores the DTC.

DTC No.
DTC Detection Condition
Trouble Area
P0560
An open in the ECM back-up power source circuit (1 trip detection logic).
  1. Open in back-up power source circuit
  2. Battery
  3. Battery terminals
  4. EFI MAIN fuse
  5. ECM
HINT:
If DTC P0560 is stored, the ECM does not store other DTCs and the data stored in the ECM is partly cleared.

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 (ECM - BATTERY)

2.INSPECT BATTERY

  1. Check the battery voltage.

    Standard 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.


NG
REPAIR OR REPLACE BATTERY TERMINAL
OK


4.CHECK WHETHER DTC OUTPUT RECURS

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to ON.

  1. Turn the tester on.

  1. Clear the DTCs (RAV4_ACA30 RM000000PDK0WCX.html).

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

  1. Start the engine and turn the tester on.

  1. Enter the following menus: Powertrain / Engine and ECT/ DTC.

  1. Read the DTCs.
