FAIL-SAFE 

Engine Control System 

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: SYMBOL ECM does not control the accelerator pedal releasing speed.
Device fix mode
  • This mode fixes the electric IVT control actuator and the EVT control solenoid valve in the reference position.
  • A control signals is not transmitted to the EGR volume control valve and the EGR volume control is deactivated.
Combustion control mode Stratified charge combustion control at starting No stratified charge combustion at starting (cold start).

Stop/Start System 

When a DTC is detected, the stop/start indicator lamp blinks slowly and the stop/start system operation is prohibited. When ECM detects error while operating the stop/start system, ECM restarts the engine.
