DTC Description: Fail-Safe

Fail safe mode

Vehicle behavior

Traveling control mode

ECM controls the accelerator pedal depression speed to make it slower than actual speed. This causes a drop in accelerating performance and encourages the driver to repair malfunction.

NOTE: ECM does not control the accelerator pedal releasing speed.

Combustion control mode
  • Stops feedback control of idle speed and controls with specified speed.
  • Stops recovery speed control by the fuel cut at decelerating and controls with specified speed.
