Vehicle Error Codes #724

Closed JonathanForce closed 4 months ago

JonathanForce commented 4 months ago

Hello,

For our recreational vehicles, we would like to be able to retrieve the various error codes that the vehicle may encounter.

I've noticed that some signals have an isError boolean, for example for ABS (ABS.IsError) or ESC (ESC.IsError), but this isn't precise enough for our purposes.

In TractionBattery there's an ErrorCodes signal, but it's specific to the battery.

Would it be possible to have the signal below directly in Vehicle.vspec?

ErrorCodes:
  datatype: string[]
  type: sensor
  description: Current error codes related to the vehicle

This would contain all the error codes encountered by the vehicle and we could inform the user of the problems and actions to be taken.

What do you think? Is there another/better option?

We have had Diagnostic Trouble Code (DTCs) as part of the OBD branch for a while, and as part of the OBD deprecation they were recently migrated/copied to a branch of it's own at https://github.com/COVESA/vehicle_signal_specification/blob/master/spec/Vehicle/Diagnostics.vspec


Diagnostics.DTCList:
  datatype: string[]
  type: sensor
  description: List of currently active DTCs formatted according OBD II (SAE-J2012DA_201812) standard ([P|C|B|U]XXXXX )

Thank you @erikbosch, we will use this signal for our errors. I close the issue.
