The tool I recommend for your Duramax is the Autel MaxiCOM MK808, it’s competent, does almost everything a DIYer needs to do, it’s robust, and is easy to use. Nice!īut the problem with the old Tech 2 is they were clunky and slow to use, the new system is great, but it’s a laptop/desktop-based system with a wireless interface and spendy to buy. I witnessed an apprentice test drive a truck with a Tech 2 trailing from the door jam. The old GM Tech 2 scanners were tough, no doubt about it. The newer vehicles used the wireless MDI system. At the dealership, I used the bulletproof GM Tech2 handheld scanners for the older trucks. Tools that are up to the job are important. What You Need From A Scannerĭuramax is a no-nonsense get her done kind of engine, and in my experience, the owners tend to be of a similar build – hard-working, DIY, salt of the earth, no BS, get her done types. You’ll also learn some of the common issues I met as a Duramax mechanic working at the dealership. In this post, you’ll learn why I like the Autel MaxiCOM for the Duramax. The MaxiCOM performs simple tasks such as reading and clearing fault codes, resetting service intervals, codes injectors, keys, performs relearn procedures for transmission, throttle, steering angle sensors, codes new batteries, performs DPF regens. The best scanner for a Duramax is the Autel MaxiCOM Mk808.
I’m a GM-trained technician, and I’ve worked on a ton of Duramax trucks. Working on a Duramax is not for the faint-hearted, but you already know that.
