Code P0560 2005 Toyota Highlander Description

The battery supplies electricity to the Engine Control Module (ECM)even when the ignition switch is off. This power allows the ECM to store data such as Diagnostic Trouble Code (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 Malfunction Indicator Light (MIL) and stores the DTC.
