What is the fault with Dongfeng Tianlong EECU?
1 Answers
It is a wiring issue that prevents the Vehicle Electronic Control Unit (VECU) from receiving signals from the Engine Electronic Control Unit (EECU). Below is an introduction to the EECU: 1. Composition of the EECU: The EECU, or the vehicle's computer board, consists of a microprocessor (CPU), memory (ROM, RAM), input/output interfaces (I/O), analog-to-digital converters (A/D), as well as large-scale integrated circuits for shaping and driving. 2. Function of the EECU: The primary role of the EECU is to monitor information from various sensors on the engine and messages sent by the VECU via the CAN bus, enabling control over components such as the exhaust brake solenoid valve, electric fan, and fuel injector solenoid valve to ensure the engine operates normally. The main purpose of the EECU is to collect various signals and act as the computer that controls the engine's proper functioning.
