Fail-Safe Table
When any of the following DTCs is detected, ECM enters fail-safe mode as long as malfunction continues to exist but
that mode is canceled when ECM detects normal condition after that.

Engine General Information and Diagnosis:
Fail-safe operation
ECM stops air/fuel ratio control.
• ECM controls injector drive time (fuel injection
volume) according to throttle valve opening
(closed throttle position or not).
• ECM stops EGR control.
ECM controls actuators assuming that intake air
temperature is 20 °C (68 °F).
• ECM controls actuators assuming that engine
coolant temperature is 80 °C (176 °F).
• ECM operates radiator cooling fan.
• ECM turns off throttle actuator control relay and
throttle valve is fixed at the opening of about 7°
from its completely closed position (default
opening).
• ECM controls fuel cut at specified engine speed.
• ECM stops air/fuel ratio control.
• ECM turns off throttle actuator control relay and
throttle valve is fixed at the opening of about 7°
from its completely closed position (default
opening).
• ECM controls fuel cut at specified engine speed.
• ECM stops air/fuel ratio control.
ECM stops air/fuel ratio control.
• ECM turns off throttle actuator control relay and
throttle valve is fixed at the opening of about 7°
from its completely closed position (default
opening).
• ECM controls fuel cut at specified engine speed.
Ignition timing is fixed.
ECM controls actuators assuming that vehicle
speed is 0 km/h (0 mile/h).
• ECM turns off throttle actuator control relay and
throttle valve is fixed at the opening of about 7°
from its completely closed position (default
opening).
• ECM controls fuel cut at specified engine speed.
ECM controls fuel cut at specified engine speed.
• Throttle valve is fixed at the opening of about 7°
from its completely closed position (default
opening).
• ECM controls fuel cut at specified engine speed.
• ECM turns off throttle actuator control relay and
throttle valve is fixed at the opening of about 7°
from its completely closed position (default
opening).
• ECM controls fuel cut at specified engine speed.
