DTC Description: Fail-Safe

Engine operating condition in fail-safe mode

Fail safe mode

Vehicle behavior

Traveling control mode

Accelerator angle variation control

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.

Engine output control

ECM reduces the engine output, according to the rise in engine speed. This reduces the vehicle speed to encourage the driver to repair malfunction.

Driving at 40 km/h (25 MPH) or more is possible.

NOTE: This value is a reference value converted from engine power to vehicle speed.

Actual power limitation value differs due to the malfunctioning part and driving condition.
