U760E Automatic Transaxle

U760E AUTOMATIC TRANSMISSION / TRANSAXLE: AUTOMATIC TRANSAXLE SYSTEM: P0560: System Voltage
P0560 - System Voltage

DESCRIPTION

The battery supplies electricity 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, this memory 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 store the DTC.

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