What is the issue with engine module failure?
1 Answers
ECM failure indicates a problem with the power module or the engine. The full name of Engine ECM is: Engine-Control-Module, which is the 'Engine Control Module'. Generally, it is currently referred to as 'ECU' in the industry: Electronic-Control-Unit, the electronic control unit. Composition of the control system: In simple terms, the control system of an electronically controlled engine consists of three parts: the Sensor, the Electronic Control Unit (ECU), and the actuator. The ECU serves as the 'brain' in this system. Functionally, it is a dedicated microcomputer controller for the engine. Like a regular computer, it is composed of a microprocessor (CPU), memory (ROM, RAM), input/output interfaces (I/O), analog-to-digital converters (A/D), as well as shaping, driving, and other large-scale integrated circuits. Working principle: During operation, the ECM collects information about various working states of the engine through various sensors (including temperature sensors, pressure sensors, rotation sensors, flow sensors, position sensors, oxygen sensors, knock sensors, etc.), which are then transmitted to the ECU via dedicated lines.
