List Of 2016 Silverado Check Engine Light And Remote Start Won't Work References. Cause if the light is on, the remote start won't work. I've tried my other brand new remote as well.

If the obd system is not working properly, it may not allow the engine to be started remotely. In some cases, the check engine light may also prevent the remote start from starting the engine as a precautionary measure. Regardless, the check engine light / hard to start inspection is the best way.
