DTC P0560 System Voltage


DESCRIPTION

The battery supplies electricity to the ECM even when the engine 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
Open in the ECM backup power source circuit (1 trip detection logic).
  1. Open in backup power source circuit
  2. Battery
  3. Battery terminals
  4. EFI 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.

CONFIRMATION DRIVING PATTERN

  1. Turn the engine switch on (IG) and wait for 5 seconds or more.

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 GTS. 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 positive (+) battery terminal.

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

    Standard Resistance:

    for RHD
    Tester Connection
    Condition
    Specified Condition
    A52-1 (BATT) - Battery positive (+) terminal
    Always
    Below 1 Ω
    A52-1 (BATT) or Battery positive (+) terminal - Body ground
    Always
    10 kΩ or higher

    for LHD
    Tester Connection
    Condition
    Specified Condition
    A38-1 (BATT) - Battery positive (+) terminal
    Always
    Below 1 Ω
    A38-1 (BATT) or Battery positive (+) terminal - Body ground
    Always
    10 kΩ or higher

2.INSPECT BATTERY
  1. Check that the battery is not depleted (Click here).

    OK:
    Battery is not depleted.


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 BATTERY TERMINAL
OK


4.CHECK WHETHER DTC OUTPUT RECURS
  1. Connect the GTS to the DLC3.

  1. Turn the engine switch on (IG).

  1. Turn the GTS on.

  1. Clear DTCs (Click here).

  1. Turn the engine switch off.

  1. Turn the engine switch on (IG) and turn the GTS on.

  1. Wait 5 seconds or more.

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

  1. Read DTCs.
