But does it actually help?
I just brought my car in for an airbag light and inspection. They read the codes and stopped without charging me anything. They handed me the manufacturer printout of possibilities and future steps, and recommended I goto the dealer for a related recall. Of course the recall wasn’t enough so now I’m out thousands.
I know this is just one example but reading the codes myself would have made no difference. As far as I can remember out of all the problems with all the cars over the years, reading the codes would never have made the difference. I’m tempted because it’s cheap and knowledge is power, but realistically I don’t see it helping
Maybe this is directly related to how much work you can do on your own vehicle, when guided by a problem code, but I’ve never had a scenario where this was even close
