  • Feature list: Scan the feature list to decide if the GM code reader has the key aspects you need. For example, Freeze Frame or ABS/ARS codes or Transmission codes.

Other Consideration

If you are willing to experiment and self-learn, the DIY devices would be very cost-effective as they save the cost incurred for hired professional help.

With information always a click away, it never hurts to check reviews and customer views before zero in your model.

Compare products in a similar price range, especially concerning working methodology. Do not invest in a high model that has features that you will never use.
