Engine Control Module: Description and Operation
Fail-Safe Operation
Even when a trouble has occurred in such area of engine & emission control system that includes the parts described in fail-safe table of the
Engine section and a failure signal is sent to ECM, control over the injector, ISC actuator and others is maintained on the basis of the standard
signals and/or back-up program prestored in the ECM while ignoring that failure signal and/or CPU. This function is called "fail-safe function".
Thus, with this function, a certain level of engine performance is available even when some failure occurs in such area and disability in running is
avoided.
