FAIL-SAFE
Engine operating condition in fail-safe mode
Fail safe modeVehicle behavior
Traveling control modeAccelerator angle variation controlECM 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.
noteECM does not control the accelerator pedal releasing speed.
Device fix mode
  • This mode fixes the electric IVT motor and the EVT control solenoid valve in the reference position.
  • The intake manifold runner control valve motor is turned OFF (intake manifold runner control valve opens).
  • A control signals is not transmitted to EGR volume control valve and the EGR volume control is deactivated.
Combustion control modeStratified charge combustion control at startingNo stratified charge combustion at starting (cold start).
