AUTOMATIC TRANSMISSION SYSTEM, Diagnostic DTC:P0560

DTC Code DTC Name
P0560 System Voltage

DESCRIPTION

The battery supplies electricity to the TCM even when the engine switch is off. This power allows the TCM to store data such as DTC history and freeze frame data. If the battery voltage falls below a minimum level, the stored 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 this DTC.

DTC No. DTC Detection Condition Trouble Area

Tech Tips

If DTC P0560 is set, the TCM does not store other DTCs.
