Fail Safe

INFOID:0000000012198247

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) and device fix

mode.

ECM

Fail Safe Pattern

Fail Safe List

Fail safe mode

Vehicle behavior

Traveling con-
trol mode

Accelerator an-
gle 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.
• Engine output control 1: Limits the maximum speed to 120 km/h (75 MPH)*
• Engine output control 2: Limits the maximum speed to 55 km/h (34 MPH)*
*: 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

• This mode fixes the IVT control solenoid valve and the EVT control solenoid valve in the refer-

ence 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).

Combustion
control mode

Stratified charge
combustion
control at start-
ing

No stratified charge combustion at starting (cold start).

Idle speed con-
trol

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

Recovery speed
control at decel-
erating

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

Idle neutral con-
trol

Stops idle neutral control.

Ignition timing
correction con-
trol

Partially controls ignition timing control.

Retardation
control

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