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, freeze frame data and fuel trim values. 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. When the engine is next started, the TCM will illuminate the MIL and set the DTC.

DTC Code DTC Detection Condition Trouble Area
P0560 TCM back-up power source circuit voltage is low (1 trip detection logic).

  • Back-up power source circuit

  • TCM

Tech Tips

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