Resets service intervals, codes injectors, keys, performs relearn procedures for transmission, throttle etc. Range of functions – It reads codes and live data on all systems not just the powertrain.Easy to use – Hook up and finds your vehicle automatically, color touch screen with big clear buttons.Strong and reliable – I’ve been using Autel products for years and have yet to break one.The extra functionality of the pro-type bidirectional tool allows you to operate components from the scan tool, capture live data, and adapt components after fitting.įor most DIYers the Autel MaxiCOM is great. Bidirectional tools are pro tools and you already know these guys are typically not cheap. If you are dealing with a more complex problem you’ll need a bidirectional scanner.

You can check out all scanners here on the Mechanics tools page. Autel has a less expensive reader for that too.īut, if you need to go delve deeper and run more sophisticated tests and adaptions, you’ll need a bidirectional scanner. If you simply want to read powertrain fault codes, that’s fine. 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.

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.
