What is the reason for Dongfeng Tianlong EECU?
1 Answers
Dongfeng Tianlong EECU is caused by circuit issues, which prevent the Vehicle Electronic Control Unit (VECU) from receiving signals from the Engine Electronic Control Unit (EECU). Below is an introduction to the EECU: Composition of the EECU: The EECU in vehicles consists of a microprocessor (CPU), memory (ROM, RAM), input/output interfaces (I/O), analog-to-digital converters (A/D), and large-scale integrated circuits for signal conditioning and driving. Function of the EECU: The main function of the EECU is to monitor signals from various sensors on the engine and information 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 proper engine operation. The primary role of the EECU is to collect various signals and serve as the computer that controls normal engine operation.
