Description

The GM MDI 2 is the next generation Global Diagnostic Interface tool for both current and future vehicles starting with Global A vehicles, and extending through future vehicle protocols and architectures. It's a compact communication module with increased processing power and security that manages the transfer of data between a vehicle's onboard ECU network with an auxiliary CAN bus. The GM MDI 2 replaces the MDI introduced in 2007 and offers faster programming speed than the MDI. The MDI 2 can be used to perform Pass-Thru programming on all vehicles built since 1996 and into the future. Servicing the current generation Global A vehicles will require the diagnostic software, GDS2, Global Diagnostic System 2 running on a local PC device while the MDI or MDI 2 is connected to the vehicle. The MDI 2 connects to the vehicle via the J1962 connector using a new DLC cable. Connection between the MDI 2 and the PC can be accomplished via standalone (USB) or through a NEW Point-to-Point wireless feature, and the dealership network (CAT5, or Wireless). Kit includes: MDI device, DLC Cable SAE J1962, 10-ft. USB A to USB B Cable, Ethernet Cable, Two pcs. of D-Link Wireless USB Adapters (Dongles) for wireless connection Note: This product requires the GM GDS2 software.

  • Genuine Bosch tool !
Genuine Bosch tool! As a GM technician for 40 plus years , I've bought and used numerous diagnostic interface tools to use with GM GDS2 , SPS2 , Tech2win, as well as the GM data bus diagnostic programs, have had a Dealer supplied MDI 2 from Bosch since they came out, always works ! Do Not buy the Chinese knock off versions ( labeled Made in China) - if you try to use them with the GM programs , GM will lock out your account!!! Just wanted to own my own MDI 2 Tool and Amazon Prime Days sale made it affordable at 25% off ... show more

  • The real MDS2. Complete with cables and dongles
I decided to go this route after reading about a competitor or two. I decided on this to reduce future hassles working on my GM stuff. The package arrived quickly, in good shape, and complete. I purchased the subscriptions I need, learned the steps to load the software and connect the interfaces. Next thing, my Volt was fixed. (Battery pack is fine, and the codes are gone, thank you) Onto my next projects. ... show more

  • Genuine Bosch MDI 2
This is a true authentic bosch gm MDI 2. Do not believe the reviews or posts stating that because it has the lower case gm logo it's a fake. GM switched to the lower case logo around 2021 and eventually the older MDI 2's with the old upper case GM letters in the blue square have cycled out. I'm a GM technician and have been using this tool, it works flawlessly. Purchase with confidence, it's from Bosch and it's genuine. ... show more

  • Verify for Authenticity!!!
WARNING!!! Verify immediately upon receiving MDI that it is authentic by serial number/part number as a Bosch MDI from Germany and not a Chinese fake counterfeit unit. My experience was the latter, fake unit. Someone swapped and returned unit for refund ($700 - $800) profit. I’m hoping for karma! These returns are being repackaged as Used, like New Condition and not being verified for part number/serial number on packaging. Also, another Dead giveaway is the missing GM logo in upper case letters. Some may come with the lower case gm sticker in box! 😡 ... show more
