كمبيوتر المحرك او كمبيوتر السيارة معطل او شورت سيركيت اسباب اعطاله وكيفية تتابع العطل الفيديو مبني على استشارة من صديق واحببت ان اشارككم المعلومة
What are the symptoms of a bad engine control module?
Usually a bad or failing ECM will produce a few key symptoms that can alert the driver of a potential issue.
Check Engine Light comes on. An illuminated Check Engine Light is one possible symptom of a problem with the ECM. ...
Engine stalling or misfiring. ...
Engine performance issues. ...
Car not starting.
An engine control unit (ECU),
also commonly called an engine control module (ECM),
is a type of electronic control unit that controls a series of actuators on an internal combustion engine to ensure optimal engine performance.
It does this by reading values from a multitude of sensors within the engine bay,
interpreting the data using multidimensional performance maps (called lookup tables),
and adjusting the engine actuators.
Before ECUs, air-fuel mixture,
ignition timing,
and idle speed were mechanically set and dynamically controlled by mechanical and pneumatic means.
If the ECU has control over the fuel lines, then it is referred to as an Electronic Engine Management System (EEMS).
The fuel injection system has the major role to control the engine's fuel supply. The whole mechanism of the EEMS is controlled by a stack of sensors and actuators
Modern ECUs use a microprocessor which can process the inputs from the engine sensors in real-time.
An electronic control unit contains the hardware and software (firmware).
The hardware consists of electronic components on a printed circuit board (PCB),
ceramic substrate or a thin laminate substrate.
The main component on this circuit board is a micro controller chip (CPU).
The software is stored in the microcontroller or other chips on the P.C.B.,
typically in EPROMs or flash memory so the C.P.U.
can be re-programmed by uploading updated code or replacing chips.
This is also referred to as an (electronic) Engine Management System (EMS).
Sophisticated engine management systems receive inputs from other sources,
and control other parts of the engine; for instance,
some variable valve timing systems are electronically controlled,
and turbocharger waste gates can also be managed.
They also may communicate with transmission control units or directly interface electronically controlled automatic transmissions,
traction control systems, and the like.
The Controller Area Network or CAN bus automotive network is often used to achieve communication between these devices.
