I need a good abs checker and srs checker for my tahoe Lt 2001 that lets me know the problem of the vehicles abs and srs light in the dashboard or just a good machine that checks everything on my car including srs and abs faults in detail
Well unfortunately nothing cheap that does that kind of data but call the guys at Blue driver. You're going to look it up it's a Canadian competent and they sell a scanner that hooks up to your fancy phone for about $129 bucks now and they can do quite a lot they will tell you if it will do what you want for your vehicle. I have machines that do that but they started that over a $1,000
The GM dealer scan tool for that vehicle is a Tech2. With that you'd be able to do everything the dealer could do as far as electronic diagnostics. You may be able to find a used one, or Chinese-made clones are available for a few hundred dollars.
