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 (M13 ENGINE) 6-2-19
FAIL-SAFE OPERATION
• ECM controls injector drive time (fuel injection vol-
ume) 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).
ant temperature is 80°C (176°F).
• ECM operates radiator fan.
• ECM controls actuators assuming that throttle open-
ing is about 20 deg.
• Fix ignition timing.
• ECM changes injection control system from
sequential injection to simultaneous one.
ECM changes injection control system from sequential
injection to simultaneous one.
ECM controls actuators assuming vehicle speed is 0
km/h (0 mile/h).
ECM controls actuators assuming that barometric
pressure is 101.33 kPa (762 mmHg).
