2: wifi card compatible
So far, Chinese clone GM MDI with squ wifi card

3: wifi is not working but works fine with USB

I bought a cheap one and it only worked with usb. The wired network and wifi did not work. In fact, the card flash socket was missing from the board. Build quality was not to bad. I just use it to flash newer pcm/ecm’s.

Part 2: Why GM MDI instead of Tech II scanner?

Flash faster: MDI & GDS2

As for why GM is going to the GM MDI and GDS2, instead of using a Tech II with TIS2000 software, because the MDI with GDS2 flashes a hell of lot faster when you have flash a new module with either it orginal firmware or upgraded firmware. Its also faster to use than having to press buttons on the Tech II for basic commands during diagnostics as well.

Older cars: Tech II & TIS2000

So in regards to the vets, Tech II clone will cover all the C6 cars and older since the last of the updated firmware on the unit covers from here back. If you do need to reflash something, it’s done via Tis2000 with the Tech II as the pass through device.

New & old cars: MDI interface

Since GM did not make upgraded firmware to flash into the Tech II’s to cover these cars like C7, then it’s a MDI that is needed instead. As for the MDI’s firmware, they will cover not only the new cars, but the cars that the old Tech II’s used to cover as well.

Now the glitch on the MDI regarding cloning it, since it has to use the GDS2 software for the pass through only device, GDS2 software has not been cracked like Tis2000 software has been instead.

GM account for subscription: MDI need it

So the only way that even a clone MDI is going to work, is to have a subscription to GM (Few $K a year) to allow you to use the GDS2 software that has to log into GM each time it used instead.

Hence the Clone Tech II unit you get will already be loaded with the most current firmware, and for most of the stuff you going to use the Tech II clone, will just be using the unit by itself without being connected to a laptop.

Also the cracked copy of Tis2000 that you get with the clone model, does not have to be connected/logged into GM to use it for 99% of the stuff (do not need an account with GM).

Note, if push comes to shove and you can not find a copy of the needed firmware to flash into a unit to upgrade a module, then you can get a one day subscription to GM to pull down the needed file from them.

Part 3: GM MDI alternative: VXDIAG VCX NANO GM device

Confirmed: VXDIAG VCX NANO GM device works as a clone to the GM MDI.
since it also comes with GDS2 as well to work on newer cars.

I ordered and received a VXDiag VCX Nano on Saturday. I currently have a Tech 2 clone unit.

I primarily bought it for the later cars which use GDS2/MDI, specifically a Chevy Cruze and a ’15 C7. I also bought a refurbished HP Elitebook running Windows 7 Pro 64-bit on a dual core I5 processor.

The software CD that comes with the VCX Nano I received has two install routines with installation instructions that were brief and somewhat minimal. One install routine for Tech2Win and one for GDS2. The Tech2Win software installs and runs under native Win 7, and with not too much trouble that was up and running, and I could use it on an ’01 Vette.

Install the VM player as admin (right click on it and select run as admin).

Once have vm player installed on your machine, forget all about the VM player app start icon, since you not going to use it, since the xp version it has set up under it, will not work with nothing else but GDS2.

Now copy the GDS2 folder from the disc, to somewhere on your drive (folder and the files in it).

Now in that GDS2 folder you just copied to your hard drive, your going to right click on the VM.vmx file inside that folder and select to open it with Vm player app (selected from programs from the list).

If you want a icon to click on to open the GDS2 program via VM player without having to go into the folder each time, do a copy on the VM.vmx file via the right click method, go over to your desk top, do a right click paste of it there to make a short cut, do another click on the shortcut icon you just pasted into desk top, go down to rename, and just change the shortcut name to GSD2. Now when you click on the new icon named GSD2 you just made, it will open up GDS2 in the vm player.

If you want the icon in the start drop down menu, then right click on it again, and select pin to start menu (classic in my case, since I run classic shell since windows 8).

Hence you don’t start the GDS2 program by clicking on VM player, but by clicking on the vm.vmx file in the program, with it desinated to be opened up via VM player instead. Note if you do the GDS2 shortcut icon, make sure that is selected to open up with VM player as well.

Cons:

Someone think it sounds like the Nano is not an option for us novice users, Seems like a very difficult process.

That’s all.

How to solve GM MDI Interface not connecting errors

Here are all solutions aimed to help fix GM MDI Scanner multiple diagnostic interface connection/communication issues (connection by usb, wireless ethernet, wired ethernet)… big thanks to all contributors and obd2tool.com

For mdi not connecting…

First, you should make sure that the MDI Manager software should be installed on the PC and the MDI must be powered up before you use it to communicate.
Also the MDI should be configured for wired ethernet or wireless communication. If the USB is available, the MDI will connect by using the USB and if not, the MDI will connect by using wired ethernet and if neither of them is available, the MDI will connect by using wireless.
If the MDI can not communicate with the MDI, you should check the cables if they are securely attached to the MDI, if the MDI has completed its power up sequence, if the connector pins are clean and if the MDI Manager software is running.

In detail…. mdi connection can be discussed in the following 4 parts:

Part 1: GM MDI USB connection
Part 2: GM MDI connection by wireless ethernet
Part 3: GM MDI connection by wired ethernet
Part 4: Tech support: GM MDI not connecting

Part 1: GM MDI USB connection

And if you connect them by USB, you need to check the MDI USB connection is detected by windows. About the solutions, you can connect the MDI to the PC USB port and power up the MDI. Open the Network and Dial-up Connections Window from the Windows Control Panel. Then check for the device name ETAS USB Remote NDIS Network Device. If it is not running, check all USB ports on the PC and verify that the MDI is powered on.

GM MDI Manual: What if MDI fails to connect on USB
interface?
*   Check USB cable connections.
*   Check Firewall Settings on your PC.
*   Verify a USB Hub is not being used (MDI has a fixed USB address).
*   Verify that only one MDI is connected to your PC using USB.
*   Verify the USB driver has been installed on the PC (look for device name ‘ETAS USB Remote
NDIS Network Device’ under Network Connections).
*   Try connecting to other USB ports on the PC.

Part 2: GM MDI connection by wireless ethernet

If you connect them by wireless ethernet, you should make sure that wireless communication is enabled and the IP configuration is properly set using the MDI Manager software. Then what you need to check is that the USB cable is not plugged in, the MDI is not being used via wired ethernet and the wireless card is properly seated in the MDI. You can contact your IT department and check that your PC is detecting the wireless access point and the correct security settings have been configured for the MDI.

GM MDI Manual: What if MDI fails to connect on Wireless
interface?
*   Check the wireless card is properly seated in the WiFi GM MDI.
*   Confirm LEDs on the wireless card are lighted when the MDI is powered.
*   Verify the MDI and PC are within range of the Access Point or Router.
*   Verify that the PC is connected to the Access Point or Router.
*   Verify signal strength of the wireless network from the PC.
*   Check Firewall Settings on your PC
*   USB connection takes precedence, unplug USB cable.
*   Wired Ethernet connection takes precedence, unplug Ethernet cable.
*   Connect to MDI using USB and run MDI Manager to verify the Wireless Settings are
configured correctly.
o Wireless interface is enabled.
o AP settings configured for proper security (authentication, encryption).
o Signal Quality (fair, good, excellent) indicates connected to AP.
o The MDI, PC and AP are on the same subnet
o If using static IP, verify the IP Address and Subnet mask are correct (supplied by network
administrator.

Part 3: GM MDI connection by wired ethernet

And if you connect then by wired ethernet, you need to ensure that the wired ethernet communication is enabled and configured using the MDI Manager software. Then you should check that the USB cable is not plugged in and the MDI device detects wired ethernet activity by viewing the lights blinking on the wired ethernet port of the MDI. And also you can contact your local IT department and check that the MDI and the PC are on the same subnet.

GM MDI Manual: What if Car Diagnostic Tool MDI fails to connect on Wired
Ethernet?
*   Check Ethernet cable connections.
*   Check Firewall Settings on your PC.
*   Verify the MDI and the PC are cabled into separate LAN connections on the same network.
*   Verify that the PC is properly configured and can communicate on the network.
*   USB connection takes precedence, unplug USB cable.
*   Connect to MDI using USB and run MDI Manager to verify the Wired Ethernet Settings are
configured correctly.
o Wired Ethernet interface is enabled.
o If using static IP, verify the IP Address and Subnet mask are correct (supplied by your
network administrator).

Part 4: GM MDI not connecting

This is professional technical support for the error ” not connected to MDI”.

All what you need do is to refresh the GM MDI firmware

*   Press this button and connect the power:

*   Keep press this button and connect it to power, the power light will be on, wait about 10 seconds:

The GM MDI replaced the Tech2 as the J2534 dealership scan tool starting with the 2008 model year, though there was some overlap with existing models thru 2013 when the Tech2 was finally no longer supported for new vehicles. For new models introduced from 2010 and later, the GM MDI or MDI 2 are the only diagnostic and calibration programming tools utilized at your GM dealer.

The MDI is not compatible with the legacy DVD based TIS2000 and only works with TIS2Web online, where you can use either SPS or the Global Diagnostic System (GDS) 2 online software. You can also subscribe to the Tech2Win software at www.acdelcotds.com which is a Tech2 emulator for working on vehicles prior to the 2008 model year in lieu of a physical Tech2 tool.

The reviewed Car Scanner MDI knock-off / clone / replica tool has a S/N of 22129579 (all of them from this factory have the same serial number) and supports all Chevrolet, Buick, Cadillac, Oldsmobile, Pontiac, Saturn, GMC, Hummer, Opel, Vauxhall, Isuzu, Saab, Daewoo and Holden makes and models of the applicable years. I purchased it on obd2tool.com

Anyone know GM TECH2 and MID diagnostic tools

6-1

What is the difference between the TECH 2 hand held tool and the newer MID interface you use with a laptop? From what I read, the MID will replace the TECH2 but currently it doesn’t diagnose, just program. I need to diagnose a few issues on a 2007 Silverado, 2012 Cruze and 2013 Cruze flood car. The clones are under $400 so it might be time to get one.

The Cheap $224.00 to $400.00 Tech 2s, made in China and don’t even bother having updates installed.They will crash when when updates are installed.Overall the clone Tech 2s are good for what you are doing and are good as the real version now made by Bosch.The real version was made by Vetronix,Bosch bought out Vetronix in 2003.Also make sure it has the Candi box with it,a must for these CAN vehicles.

The last update for the tech 2 has already come out so, I would think about buying a new one unless you work on a lot of GM products.

Depending on the vehicle you’re working on, the GM MDI (Multiple Diagnostic Interface) will do everything a Tech 2 will do but, you’ll need a laptop and GDS software. Going forward from the 2013 model year, the MDI with a laptop will be the GM Diagnostic tool.

General Motors (GM) has launched Global Professional Diagnostic Tool (GDS 2) – its next generation, PC-based vehicle diagnostic system. GDS 2 is a PC-based platform that builds on the original GDS application, but also incorporates several new features, based on technician input. Combined with a Multiple Diagnostic Interface (MDI), GDS 2 provides an exclusive, effective and efficient system for the diagnosis of all the automaker’s new Global Architecture vehicles.

Cloned GM MDI possible work with Ford IDS software

Is clone GM MDI interface possible to work with Ford IDS without limitations?
Also is there anyway to convert MDI to a VCM II by flashing it? They seem to be very similar. But how to?

Look here and know how mates experienced talk about it…some say yes, some no, some possible…

Reply 1: As i know, GM MDI and Ford IDS are two different scanners.
The GM MDI can’t work with Ford IDS

Reply 2: Possible but not easy…Requires editing of the Dynamic link library files and more.

i have had MDI Working with it for a long time for personal use
Since version 97.xxx it is easier than say 96.01 because when they changed things to block clones in this version, they basically changed the file structure to that of an MDI.

Reply 3: My dilemma is deciding to get rid of my MDI clone that I purchased 1 year ago (I sold my GM car and bought a Ford so I don’t need it anymore) or try to use the gm mdi software on a Ford vehicle. I don’t have the money to purchase a genuine VCM II and I don’t want to buy a clone either.
I just want to update a few things on my Ford since the warranty is over.
I need to update the GPS module and activate the digital speedo. Looks like I’ll just leave it alone before I screw things up.

Reply 4: I have the same mdi and try flash the sd card put it in recovery mode with ford manager and don’t work when I try back to gm the tool never responding again the hardware damage and leds turn on red beeping so I think you sell that mdi and then buy a vxdiag vcx nano for ford I have one and working

Reply 5: There must be a way to flash the FPGA to a VCM. Once that’s done you can probably recovery the SD card.
The SD cards can also be copied using a tool called USB Image Tool so I’m sure you can recover your MDI.
I just don’t want to bother with it because I don’t know if it will work.
I might sell it and buy another clone. I haven’t decided yet. The MDI clone looks so much better than the VCM clone.

Reply 6: GM MDI and Ford VCM II are made by Bosch ETAS as well as Alliance VI+ or as many OEM tools now
But this one are a little bit different architecture.
So as we discussed many times and Nr. Vag Vag already confirmed in the forum you can use VCM II with Tech2Win and GDS2 but not fully
You can use VCM II with Nissan Consult III Plus but also hot full
Well I didn’t checked GM MDI with Ford IDS but I’m very sure tgat you are waisting your time for the moment.
When IDS will cover J2534 tool then you maybe will be happy to us the GM MDI with IDS but for the moment forget about
I changed the SD card in VCM II clone because this one was defective ( so a fresh untouched sd card – just formated ) and I only put it in Recovery Mode and I fix it. But I’m not sure that you can do it the same with a GM MDI.
You can try it.
Good luck

Reply 7: Well I suppose that you need an account/subscription
But if you know what exactly calibration you need you can download it from obd2tool.com
Good luck

Reply 8: Forscan as you can see it can works with a simple tool elm 327 software or with a Passthru J2534 tool
Gm Mdi it is a J2534 tool that’s why is working
Ids is different.

Good luck
