What does the CAN communication fault in Auman truck engine mean?
2 Answers
This fault code indicates a short circuit in the engine communication line. Turn off the power and measure the resistance to check if it is 60 ohms. Below is relevant information about the CAN communication bus in vehicles: 1. Overview: CAN stands for Controller Area Network, developed by the German company BOSCH, renowned for its research and production of automotive electronic products. It has become an international standard (ISO11898) and is one of the most widely used field buses globally. 2. Advantages: CAN's high performance and reliability have been recognized, and it is widely applied in industrial automation, marine, medical equipment, industrial devices, and more. Fieldbus is one of the hotspots in the development of automation technology today, hailed as the computer local area network in the automation field. Its emergence provides strong technical support for real-time and reliable data communication between nodes in distributed control systems.
The meaning of CAN communication failure in the Auman truck engine is that there is a problem with the signal transmission between the electronic control units on the truck, like the vehicle's 'nervous system' being disconnected, causing the engine and other components to fail to communicate properly. I've personally encountered many similar cases, with common causes including aging or broken wires, loose or oxidized connectors, or software bugs in the controller. Symptoms you might notice: warning lights on the dashboard, unstable engine idle, or poor acceleration. If not repaired in time, it can affect power output and fuel consumption, posing significant safety risks. Diagnosis requires using an OBD scanner to read the fault codes, and repairs may involve replacing wires, tightening connectors, or updating the system. For prevention, regularly inspect the wiring for waterproofing and dust protection, and avoid long-term parking in damp environments.
