Fail Safe

Fail safe mode

Vehicle behavior

Pattern

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.

A

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 (43 MPH) or more is possible*

*: 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.

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*

*: 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.

C

Device fix mode

• This mode fixes the IVT control solenoid valve and the EVT 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).

D

Combustion control mode

Stratified charge combustion control at starting

No stratified charge combustion at starting (cold start).

E

Idle speed control

Stops feedback control of idle speed and controls with specified speed.

F

Recovery speed control at decelerating

Stops recovery speed control by the fuel cut at decelerating and controls with specified speed.

Idle neutral control

Stops idle neutral control.

Ignition timing correction control

Partially controls ignition timing control.

G

Retardation control

Controls ignition timing delay control in the intermediate water temperature range.

DTC No.

The ECM controls the electric throttle control actuator in regulating the throttle opening in order for the idle position to be within +10 degrees.

The ECM regulates the opening speed of the throttle valve to be slower than the normal condition.

So, the acceleration will be poor.
