Introduction to the Function of the Relay Below the Refine Steering Wheel
1 Answers
The relay located below the Refine steering wheel records and displays the OBD (On-Board Diagnostics) data of the vehicle's computer, which includes a driving record function. It can provide operational data for various systems of the vehicle, allowing users to check the working status of each system. Generally, some data can be read through the dashboard, but there is much more data that cannot be displayed. The data recorded by OBD is more comprehensive than what is shown on the dashboard. Here is more detailed information about OBD: 1. Quickly identify fault points: OBD can read a variety of professional data such as throttle opening, air-fuel ratio, and the opening degree of the accelerator and brake pedals, as well as retrieve fault codes to quickly locate issues. 2. Fault analysis: Through data calculation, OBD can analyze faults in electronic components within the engine's electronic control system.
