Same function as in earlier Trionic T7 system. Power steering fluid pressure switch (739) Informs ECM when power steering servo pressure exceeds 17 bar. Used for idle speed compensation. Level monitor, engine oil (243) Informs ECM when oil level is low. Used for indication on Saab Information Display (SID). Level sensor, fuel (46)
A typical ETC system consists of three major components: (i) an accelerator pedal module (ideally with two or more independent sensors), (ii) a throttle valve that can be opened and closed by an electric motor (sometimes referred to as an electric or electronic throttle body (ETB)), and (iii) a powertrain or engine control module (PCM or ECM).

An engine control unit (ECU), also called an engine control module (ECM), [1] is a device that controls various subsystems of an internal combustion engine. Systems commonly controlled by an ECU include the fuel injection and ignition systems.
An ECU from a Geo Storm. An electronic control unit (ECU), also known as an electronic control module (ECM), is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a car or other motor vehicle.
Fault detection, isolation, and recovery (FDIR) is a subfield of control engineering which concerns itself with monitoring a system, identifying when a fault has occurred, and pinpointing the type of fault and its location. Two approaches can be distinguished: A direct pattern recognition of sensor readings that indicate a fault and an analysis ...
For each component and failure mode, the ability of the system to detect and report the failure in question is analyzed. One of the following will be entered on each row of the FMECA matrix: Normal: the system correctly indicates a safe condition to the crew; Abnormal: the system correctly indicates a malfunction requiring crew action
An engine failure aboard an Air Canada Express commuter flight from Sacramento International Airport caused the pilots Tuesday to turn around and return to the capital city’s airport.
In late May 2022, Ford issued a recall for the 2021 Ford Mustang Mach-E due to an unintended acceleration issue resulting from the powertrain control module functional safety software potentially failing to detect a software error, resulting in unintended acceleration, unintended deceleration, or a loss of drive power.
