DTC    P0560    System Voltage

DESCRIPTION

The battery supplies power to the TCM even when the ignition switch is off. This power allows the TCM to store data such as DTC history, freeze frame data and fuel trim values. If the battery voltage falls below a minimum level, the TCM data is cleared and the TCM determines that there is a malfunction in the power supply circuit. The next time the engine is started, the TCM will illuminate the MIL and store the DTC.

DTC No.
