Delco ECU used in General Motors vehicles built in 1996. 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.
Sudden uncommanded opening of engine throttle in certain models of modern, ECU-controlled automobiles have been replicated multiple times in laboratory settings. [ 21 ] [ 22 ] A negative surge of voltage (down to 7V) can cause rebooting of the ECU, resulting in the output APS (accelerator position) and TPS (throttle position) reaching 100% ...
The recall concerns the airbag module, which can cause the airbag to inflate improperly. Toyota also announced a recall affecting 270,000 MY 2006-2012 Lexus IS models. This recall concerns loose nuts on the wiper blades, which can cause the wipers to fail, especially if there is a heavy buildup of snow.
OBD-II provides access to data from the engine control unit (ECU) and offers a valuable source of information when troubleshooting problems inside a vehicle. The SAE J1979 standard defines a method for requesting various diagnostic data and a list of standard parameters that might be available from the ECU.
A power-train control module, abbreviated PCM, is an automotive component, a control unit, used on motor vehicles. It is generally a combined controller consisting of the engine control unit (ECU) and the transmission control unit (TCU). On some cars, such as many Chryslers, there are multiple computers: the PCM, the TCU, and the Body Control ...
MIL on a running engine indicating malfunction in engine control system. A check engine light or malfunction indicator lamp (MIL), is a tell-tale that a computerized engine-management system uses to indicate a malfunction or problem with the vehicle ranging from minor (such as a loose gas cap) to serious (worn spark plugs, engine problems or a ...
A Rover V8 3.9L engine fitted with the 14CUX system. The engine control unit (ECU) of the 14CUX system is run by a Motorola MC6803U4 8-bit microprocessor, which is an uncommon variant of the otherwise ubiquitous 6803. The processor is mislabelled in the ECU, possibly to deter any reverse engineering efforts. The 14CUX determines fueling values ...
Trionic is an engine management system developed by Saab Automobile. It consists of an engine control unit (ECU) that controls 3 engine aspects: Ignition timing; Fuel injection; Acts as a boost controller. The numerical prefix 'tri-' yes (Tri being three) in Trionic. 'Ion' comes from the fact that it uses ion current, measured by the spark ...
