Fail Safe (Turbo High Pressure Model): Description

WARNING: This page is about a different variant/trim than selected.

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.

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.
Traveling Control Mode	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: Driving at 70 km/h or more is possible. Engine output control 2: Driving at 40 km/h 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).
	Idle speed control	Stops feedback control of idle speed and controls with specified speed.
	Recovery speed control at decelerating	Stops recovery speed control by the fuel cut at decelerating and controls with specified speed.
	Ignition timing correction control	Partially controls ignition timing control.
	Retardation control	Controls ignition timing delay control in the intermediate water temperature range.
