Title: U660F (AUTOMATIC TRANSMISSION / TRANSAXLE): AUTOMATIC TRANSAXLE SYSTEM: P0560; System Voltage; 2016 MY Sienna [12/2015 - 08/2016]

DTC

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, these memories are cleared and the TCM determines that there is a malfunction in the power supply circuit. When the engine is next started, the TCM will turn on the MIL and store the DTC.

DTC No.

DTC Detection Condition

Trouble Area

P0560

Open in TCM back-up power source circuit.

DTC is detected for 3 seconds or more (1 trip detection logic).
  • Open in back-up power source circuit
  • TCM

HINT:

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