Get the code read. That will tell you what needs to be fixed.

 

Keep in mind though that most of the consumer-grade scan tools, including those the local auto parts stores use, will only read engine codes and often will not read ABS or air bag codes. So if you stop by a parts store and they tell you there are no diagnostic codes, that's just because their tool will not pull air bag system codes.

I should have added that info. Mostly a dealer only service.
