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. When the engine is next started, the TCM will illuminate the MIL and set the DTC.
| DTC Code | DTC Detection Condition | Trouble Area |

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