A Can Bus To Obd2 Converter offers a simple solution for accessing valuable vehicle data. Many aftermarket car accessories, such as gear shift lights, tachometers, and digital gear displays, require specific electrical signals often unavailable in modern vehicles. These converters bridge the gap by tapping into the car’s CAN bus network through the OBD2 port and translating complex data into usable signals.
The installation process is straightforward. Locate your car’s OBD2 port, usually within two feet of the steering wheel. Plug the CAN bus to OBD2 converter into the port and start the engine. The converter will then communicate with the vehicle’s CAN bus network. A red LED indicates the initial synchronization process, which may take a few moments. Once the correct protocol is established, a flashing green LED signals that the device is actively extracting and converting data.
The converter outputs four key signals: RPM, speed, engine running status, and vehicle motion status. The RPM signal, transmitted via a blue wire, is a 12V square wave. Its frequency increases proportionally with engine speed, providing two pulses per crankshaft revolution. Similarly, the speed signal, carried by a green wire, is also a 12V square wave, with its frequency increasing with road speed. This signal outputs approximately 2500 pulses per kilometer or 1570 pulses per mile.
The engine running status, indicated by a grey wire, provides a constant 12V signal when the engine is off or idling. This signal drops to 0V when the engine speed surpasses 350 RPM. Lastly, the vehicle motion status, using a yellow wire, outputs a 12V signal when the vehicle is stationary. This signal transitions to 0V once the vehicle exceeds a speed of 9 kilometers per hour (6 miles per hour). These converted signals empower car enthusiasts to connect a range of aftermarket devices, enhancing vehicle functionality and performance monitoring. A CAN bus to OBD2 converter provides a reliable and accessible method for unlocking your car’s hidden data.
