Volt and Spark similarities?

If a dealer can fix a Volt, can they also use the same tools to fix a Spark? They're both made by GM, so it seems like they should be able to. Does anyone know?

Not sure about that. Looks like there’s a need for some specialized software to get the diagnostic equipment working with Spark, plus a bit of training for the service crew to ensure everything operates smoothly.
