I am requesting suggestions about a truck/car code reader. I have a Dodge diesel 3500 with recurring engine light and several other vehicles now out of warranty. Not wanting to take it to a dealer as they always find big problems. I do not want one with any Blue Tooth or cloud storage apps or anything with all that tracking software, or linked to a cell phone or any of that jazz, just the handheld cheap diagnostic reader. I am going by Autozone today and have them read it, but want to buy a basic reader for home use. Suggestions?
