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 Detection Drive Pattern
DTC Detection Condition
Trouble Area
Ignition switch to ON for 3 seconds
The voltage at terminal BATT drops excessively for 3 seconds and part of the stored values in the ECM are initialized (1 trip detection logic).

Battery Voltage*
*: This is not the voltage of the BATT, it is the power supply voltage for the ECM.
HINT:
If DTC P0560 is stored, the ECM does not store other DTCs or the data stored in the ECM is partly cleared.

INSPECTION PROCEDURE

NOTICE:
  1. Inspect the fuses of circuits related to this system before performing the following inspection procedure.
  2. After replacing the ECM, the new ECM needs registration (HILUX_TGN26 RM0000012XK05BX.html) and initialization (HILUX_TGN26 RM000000TIN04CX.html).
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 to ON, even though +B voltage is present, when the voltage at terminal BATT (power supply for maintaining memorized values in the ECM) drops excessively, this DTC is stored.
