We are building a mobile application for vehicle diagnostics. We are using the ELM327 OBD-II tool for fetching the data from the car using Nodejs. The application is being built and we are facing some issue regarding certain parameters of the car. We have used and tested OBD-II in various cars and we are not getting the values of fuel level input and Vehicle Identification Number of a particular car. When we tested, we got no data as the result. How to resolve them? Any other method to get these data?
We also want to know that in any case, it is possible to detect an accident, Tow alert detection, Level of Car using Air pressure in tyres with the help of the ELM327 OBD-II.
Is there any way to control ignition on/off through OBD-II?
If you know anything related to this, Please revert back.
Thanks in advance!
