The tech II and a candi module is required to communicate with your vehicle and perform diagnostics. The MDI (multiple diagnostic interface) is used to communicate with many 2010 and newer vehicles and it can also be used for programming of older vehicles. The MDI alone is not a scan tool. It is used along with a computer and the proper software program (called GDSII) for 2010 and newer. GM is releasing a Tech II software emulator over the next couple months so Tis 2 web subscribers will be able to download a tech II simulator program to their laptops and along with the MDI.... communicate with pre 2010 vehicles using the MDI and the program which will look like a Tech II screen. The Tech II is 15 years old now and showing it's age. The memory card is installed into the Tech II and all software installations/upgrades must be downloaded thru the GM server by someone with a tis2web subscription. The card must be installed in the Tech II and the Tech II attached to the computer using a date cable (rs232 type)
will i be able to use my laptop with mdi for scanning and programming?
If you can download the program when it is released and if you have a tis2web subscription.
By Blog Post on June 1, 2011 9:59 PM| No CommentsTech2Win is a PC-based application version of the Tech 2 and CANdi (Control Area Network diagnostic interface) module that can be loaded onto a service department Techline PC or notebook computer via TIS2Web. The rollout of the application will begin in mid-June, starting with Cadillac dealerships, to be followed by Chevrolet dealerships in early July and Buick/GMC dealerships in August. The GMCL rollout will begin in early August. Look for update messages in TIS2Web, Service Information and GM Global Connect. When using the Tech2Win application, vehicle communication is performed using the Multiple Diagnostic Interface (MDI), which provides faster operation than a Tech 2 with a CANdi module.Tech2Win offers virtually the same functionality as the Tech 2. It's used for diagnostics only. Service programming is still performed through TIS2Web SPS. Refer to the Quick Reference Guide (under TIS2Web News), section 10, "Limitations," for protocols and functions not supported.Tech2Win also includes the same vehicle coverage as the Tech 2. GDS 2 still must be used when servicing Global A vehicles (Camaro, Equinox, Cruze, Sonic, Volt, LaCrosse, Regal, Terrain and SRX).InstallationBefore installing Tech2Win, the PC or notebook computer must meet or exceed the current minimum Techline hardware specifications. Review the latest specifications and guidelines at www.gmdesolutions.com. (In Canada, the IT guidelines are in the Service Library under Tools, Processes and Equipment on Global Connect.)To install the application:
Fig. 2After the application installation is complete, the diagnostic software for the desired service coverage and software license (similar to the license renewal of GDS 2) must be obtained. To download:
Fig. 35. Select Tech2 and Custom for the update mode. (Fig. 4)Fig. 46. Select the desired diagnostic software package. Available packages include the latest GM North American coverage as well as Saab and Saturn ASTRA. (Fig. 5)Fig. 57. Click Download to begin downloading the diagnostic package just like for a Tech 2. Current progress and Tech2Win will display during the download. After the download is complete, the license countdown in the lower right corner will be updated to 30. This is the number of days until the license must be renewed. When the license expires, an expiration message will be displayed. To renew the license, use the security access service or update the diagnostic software using the standard update mode. Tech2Win uses Communication Port (comm port) 9 on the PC. If this port is used for other devices, switch the comm port setting by selecting the Tech2Win Configurator icon on the desktop. Refer to the Quick Reference Guide for complete details.To access the Quick Reference Guide for additional Tech2Win installation information, go to TIS2Web News and select the Tech2Win Quick Reference Guide.When using Tech2Win, you can click the selections on screen or click the soft buttons on the screen where applicable.Tech2Win activity is shown on the bottom of the screen between the vehicle, MDI, Tech2Win and the PC. (Fig. 6)Fig. 6For more information about installing Tech2Win, review the May Emerging Issues seminar on www.gmtraining.com in the U.S.In Canada, more information about Tech2Win will be available in a future TAC Talk presentation as well as in the GDS 2/Tech2Win training course #16039.16H.- Thanks to Mike Waszczenko
