CAN bus (Controller Area Network) is a serial multi-master controller area network bus, primarily designed to connect various controllers in a vehicle, enabling communication between the engine controller, transmission controller, ABS controller, body controller, instrument panel, and other controllers. The CAN bus system not only reduces the number of wiring harnesses in the vehicle, making … Read more
5. Short Circuit of CAN L to Power (Positive) When a short circuit occurs between CAN L and the power (positive), due to the fault tolerance characteristics of the CAN bus, the entire CAN network may be unable to communicate or generate related fault codes. Because of the short circuit of CAN L to the … Read more
Sensor Everyone is familiar with sensors, right? The voice-activated lights and variable frequency air conditioners we use in our daily lives rely on sensors to perform irreplaceable roles. So let’s take a look at some small knowledge about sensors! Definition A sensor is a physical device or biological organ that can detect and sense external … Read more
Sensors are devices designed based on the physical, chemical, and biological properties and laws of materials. There are various types, and in the measurement and control field, a sensor designed based on a certain principle can simultaneously measure multiple non-electrical quantities. Sometimes, a single non-electrical quantity can be measured by various sensors based on different … Read more
