Do you know if it is possible to get DTC errors?
What vehicle do you have? If you have a Nissan LEAF then you may be experiencing this issue which has now been fixed in the latest firmware build (currently in 'edge' release channel) https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/issues/409
Thanks for the quick feedback,
I have a Twizy, but I'd like to know if it's possible on my thermal vehicle via OBD2.
I haven't seen how to do this in the documentation.
There is currently no DTC support on the generic OBD2 vehicle. It could be added though.
The Twizy DTC support is specific for the Twizy, so cannot be used on other vehicles. In theory you can read/clear DTC manually on other vehicles as well using the "xrt obd request" command, but you would need to decode the results manually. Do you want to try that?
Yes I will try like that, do you think this is the only way to get DTC back?
"xrt dtc" is only for electric cars?
Do you have more information on the "xrt obd request" command?
The returned results will be in what form?
The idea is to be able to diagnose the car at start-up, for example, and to be able to report errors.
I think we can develop a module to interpret the results.
Thank you for your answers :)
