What are the causes of ECM communication failure?
1 Answers
ECM failure indicates a malfunction in the power module or engine. Additional information: 1. The control system of an electronically controlled engine: Simply put, it consists of three components: sensors, the electronic control unit (ECU), and actuators. The ECU serves as the "brain" of the system and is essentially a dedicated microcomputer controller for the engine. 2. How ECM works: During operation, the ECM collects data on various engine operating conditions through 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 wiring. After receiving these signals, the ECU analyzes them to determine the operational status of various engine components.
