The J2534 Configuration Application

The Multiple Diagnostic Interface (MDI) is a J2534 device that connects between your computer and the vehicle’s J1962 DLC connector for pass-thru
programming of the vehicle’s ECU’s. The J2534 Configuration Application is installed onto your PC at the same time as the MDI Manager software allowing you to control how your TIS 2 Web application will connect to an MDI.
In addition, this application provides API Monitoring controls to aid in investigating problems encountered while using any J2534 devices (including the MDI).
To launch the J2534 Configuration Application from SPS, press the “configuration” button on the Diagnostic settings screen.
 
Engine Compartment

Check Engine Compartment for components which may be loose; kinked or pinched vacuum hoses or electrical connections, and for any other missing or disconnected components.
 
Check to assure that hoses and electrical wires are properly routed to provide sufficient clearance with adjacent moving or hot parts.
 
Observe the movement or freedom of movement of linkage, valves and other components.
 
Check for unusual noises within the engine compartment.
 
Visually inspect for seepage and leaks at hoses and pipe connections, seals, gaskets and plugs.
 
Tighten clamps and connectors as necessary.
 
Check power steering gear, lines and hoses for leaks and clearance with adjacent panels, moving or hot parts. Tighten clamps and connectors as necessary.
 
Test engine coolant protection.
 
Check all fluid levels; engine oil, transmission oil, power steering oil, battery, brake, and cooling system.
 
Add inspection items as needed

Check throttle linkage for freedom at wide open and closed throttle.
Check tension on all belts.
Body–Accessories
Check operation of all interior and exterior lights;
Road Test
Road test on a route with road conditions permitting the proper evaluation of squeaks and rattles.
During this test, check the following items for proper operation and function;
 
Under Vehicle:

Visually inspect vehicle undercarriage for looseness, missing components and line routing and clipping, and fluid leaks. – Tighten clamps, couplings and connectors as necessary.
Data transfer and Electronic Control Unit (ECU) reprogramming
Shop network communications (LAN and WLAN)
Future expandability, including diagnostic applications

What protocols does the GM MDI 2 support?

For immediate use — At present, vehicles have two buses on the 16 pin connector
(high speed and low speed GMLAN). The GM MDI communicates using all of the existing GM protocols, the same as the GM Tech2:
- UART
- Class 2
- KWP2000
- GMLAN (CAN)

Beginning with the 2008 model year vehicles, Pass-Thru will be the only programming method available. (Remote will continue to be available for previous vehicle)

When you test after 2010 year gm car, you can use gm gds2 software:









When you want to test before 2010 year GM car, you can use the tech2win software to test it,run fast and stable:

Difference Between Original MDI 2 and China MDI2:

GM MDI2 Clone Review:

Cars tested- success & failure list:
1: SAAB 9-5, 2003, 3.0 TID- works
mine is a clone from China.
MDI Software 8.1.135.13
GT32
SAAB NAO V9.250
Simply pressed OK when Candy detected and all worked.
Tested on SAAB 9-5, 2003, 3.0 TID

2: 2014 model - works
SAAB NAO V9.250 is from 2014. Already tested.
2003 year too old - not interesting for me.

3: Saab 9-5, 2003, 3.0 - works
Tested by my own, works with Saab 9-5, 2003, 3.0

Online or offline issues:
1: online - good, offline - bad
GM MDI good, interface works online.
update mdi 100%.
offline too bad for new cars.

2: wifi card compatible
at now, Chinese clone GM MDI with squ wifi card

3: wifi not working but works well 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.
