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 ECM 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 Code
DTC Detection Condition
Trouble Area
P0560
The voltage at terminal BATT drops excessively for 3 seconds and part of the stored values in the ECU are initialized (1 trip detection logic).
  1. Open in back up power source circuit (to BATT terminal)
  2. Battery
  3. Battery terminals
  4. EFI MAIN fuse

HINT:
If DTC P0560 is stored, the ECM does not store other DTCs or the data stored in the ECM is partly erased.

INSPECTION PROCEDURE

NOTICE:
After replacing the ECM, the new ECM needs registration (Click here) and initialization (Click here).
HINT:
  1. 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.
  2. When the ignition switch is ON, even though +B voltage is present, when the voltage at terminal BATT (power supply for maintaining memorized values in the ECM) drops excessively, a DTC is stored.
1.INSPECT FUSE (EFI MAIN)

  1. Remove the EFI MAIN fuse from the engine room relay block.

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

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    EFI MAIN Fuse
    		Always
    		Below 1 Ω
