P0560 - System Voltage

General Description
When the ignition switch is turned "ON", battery voltage is applied from the battery to the ECM through the main relay. In case that the ignition switch is turned "OFF", the ECM is supplied with power through the battery backup line to control the basic operation of vehicle.

DTC Description
If battery backup voltage drops to less than 2V when the enable conditions are met, the ECM determines that a fault exists and a DTC is stored.
