Having trouble with finding the CAN data? Checklist for beginners

24 July 2022

1. Check the CAN database

Want to know if we have parsed CAN data of your vehicle? Check the database.

2. Ask the engineers

Found it? - Send a request to the technical support. Do not forget to specify the make, model and year of manufacture of the vehicle, as well as the parameter you need to find. The specialists will tell you what settings you need to set and where to look for the parameter you are looking for. The specialist will also tell you where the connection point to the CAN-bus is located.

3. Connect via OBD

The most common connection point is the OBD socket under the steering wheel, in the glove compartment or under the dashboard of the vehicle. Sometimes you can connect directly to the twisted-pair CAN H and CAN L. Check the resistance between the wires, it should be 60 Ohm. If the resistance is about 120-150 Ohm - use a 120 Ohm resistor.

You can also connect to the CAN bus via wireless readers. They do not break the cable isolation and save the warranty of the car. However, you cannot send commands to the CAN bus, you can only receive data when connected wirelessly.

4. Record the CAN log

If you are working with the CAN bus, which is not available in our database and are having difficulty finding parameters - we can help you. The CAN Scanner has the CAN Logger function. Following the recommendations of the technical support specialist, record the operation of the CAN-bus and send it to us. We will parse the recording and show you the exact location of the necessary parameter.
