P0563

P0563 System Voltage High Input

Description

When the ignition switch is turned on, battery voltage is applied from the ignition switch to the ECM, energizing the Main relay coil. This turns ON the main relay switch, and supplies power from the battery to the ECM through the main relay switch. ECM detects supplying voltage and sets the DTC if voltage exceeds threshold value. If the signal above threshold value, the ECM judged this as a fault and DTC is set.
