DTC Description: Fail-Safe

Detected items

Engine operating condition in fail-safe mode

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 70 km/h (44 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.

Device fix mode
  • Fixes electric intake valve timing control motor in the reference position.
  • Fixes exhaust valve timing control solenoid valve in the reference position.
  • A control signals is not transmitted to EGR volume control valve and the EGR volume control is deactivated.
  • The Intake manifold runner control valve motor is turned OFF (Intake manifold runner control valve opens).

Combustion control mode

Stratified charge combustion control at starting

No stratified charge combustion at starting (cold start).
