DTC Description: Fail-Safe

NOTE: Any of the following fail-safe is applied.

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.

Combustion control mode

Stratified charge combustion control at starting

No stratified charge combustion at starting (cold start).

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 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.

Combustion control mode

Stratified charge combustion control at starting

No stratified charge combustion at starting (cold start).
