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 will illuminate the MIL and set the DTC.

DTC No.

INSPECTION PROCEDURE

УКАЗАНИЕ:
Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. 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 FUSE (EFI MAIN)


    COROLLA, AURIS. ZZE150 ZRE151,152 NDE150.Система Управления Двигателем 2Zr-Fe.Система Sfi. Dtc P0560 System Voltage

  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

  1. Reinstall the EFI MAIN fuse.
