Fail Safe
 
 
Description
When a DTC is detected, ECM executes a mode (in the Fail-safe mode) applicable to the DTC. The fail-safe mode has the preset traveling control mode (accelerator angle variation and engine output limit), device fix mode and combustion control mode.
Fail safe modeVehicle behaviorFail safe pattern
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.
A
Engine output controlECM 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.
noteThis 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.
B
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.
noteThis 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.
C
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.
D
Combustion control modeStratified charge combustion control at startingNo stratified charge combustion at starting (cold start).E
Idle speed controlStops feedback control of idle speed and controls with specified speed.F
Recovery speed control at deceleratingStops recovery speed control by the fuel cut at decelerating and controls with specified speed.
Idle neutral controlStops idle neutral control.
Ignition timing correction controlPartially controls ignition timing control.G
Retardation controlControls ignition timing delay control in the intermediate water temperature range.
Electric throttle control cancel mode ECM stops the electric throttle control actuator control, throttle valve is maintained at a fixed opening (approx. 5 degrees) by the return spring.H
