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. 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. Freeze frame data records the engine condition when malfunctions are detected. 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)

  1. Disconnect the ECM connector.

  1. Disconnect the cable from the negative (-) battery terminal.

  1. Disconnect the cable from the positive (+) battery terminal.

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

    Standard Resistance (Check for Open):
    Tester Connection
    		Condition
    		Specified Condition
    G145-17 (BATT) - Positive battery terminal
    		Always
    		Below 1 Ω
    Standard Resistance (Check for Short):
    Tester Connection
    		Condition
    		Specified Condition
    G145-17 (BATT) or Positive battery terminal - Body ground
    		Always
    		10 kΩ or higher

  1. Reconnect the ECM connector.

  1. Reconnect the cable to the positive (+) battery terminal.

  1. Reconnect the cable to the negative (-) battery terminal.

OK


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.


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 (HILUX_TGN26 RM000000PDK0T7X.html).

  1. Start the engine.

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

  1. Read the DTCs.
