AUTOMATIC TRANSMISSION SYSTEM, Diagnostic DTC:P0560

DTC Code DTC Name
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 and freeze frame data. 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. Detection Item DTC Detection Condition Trouble Area MIL Memory
P0560 System Voltage TCM back-up power source circuit is low voltage for 3 seconds or more (1-trip detection logic).
  • Open or short in back-up power source circuit

  • TCM

Comes on DTC stored

Tech Tips

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