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 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 illuminates the MIL and sets the DTC.

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)
  1. Open in back-up power source circuit
  2. EFI fuse
  3. Battery
  4. ECM
HINT:
If DTC P0560 appears, the ECM does not store other DTCs.

INSPECTION PROCEDURE

NOTICE:
After replacing the ECM, the new ECM needs registration (Toyota Fortuner RM0000012XK030X.html) and initialization (Toyota Fortuner RM0000012X2005X.html).
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, and other data from the time the malfunction occurred.
1.CHECK FUSE (EFI FUSE)


    Toyota Fortuner. Ggn50, 60 Kun51, 61 Tgn51 Lan50.1Kd-Ftv Engine Control System.Ecd System. Dtc P0560 System Voltage

  1. Remove the EFI fuse from the engine room junction block.

  1. Measure the resistance of the EFI fuse.

    Standard resistance:
    Below 1 Ω


NG
CHECK FOR SHORTS IN ALL HARNESSES AND CONNECTORS CONNECTED TO FUSE AND REPLACE FUSE
OK


2.INSPECT ECM (BATT VOLTAGE)


    Toyota Fortuner. Ggn50, 60 Kun51, 61 Tgn51 Lan50.1Kd-Ftv Engine Control System.Ecd System. Dtc P0560 System Voltage

  1. Measure the voltage of the E5 and E6 ECM connectors.

    Standard voltage:
    Tester Connection
    		Specified condition
    BATT (E5-2) - E1 (E6-7)
    		11 to 14 V


OK
REPLACE ECM (Toyota Fortuner RM0000013Z0004X.html)
NG


3.CHECK HARNESS AND CONNECTOR (ECM - EFI FUSE, EFI FUSE - BATTERY)

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

    1. Disconnect the E5 ECM connector.

    2. Remove the EFI fuse from the engine room junction block.

    3. Measure the resistance.

      Standard resistance (Check for open):
      Tester Connection
      		Specified Condition
      BATT (E5-2) - EFI fuse (2)
      		Below 1 Ω
      Standard resistance (Check for short):
      Tester Connection
      		Specified Condition
      BATT (E5-2) or EFI fuse (2) - Body ground
      		10 kΩ or higher

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

    1. Remove the EFI fuse from the engine room junction block.

    2. Disconnect the positive battery terminal.

    3. Measure the resistance.

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

REPAIR OR REPLACE HARNESS OR CONNECTOR
OK


4.INSPECT BATTERY

  1. Check that the battery is not depleted.

    OK:
    Battery is not depleted


NG
REPLACE BATTERY
OK
