03 FebHow to use GM MDI to do SPS Programming?
GM MDI is an interface between the vehicle DLC and a PC (by wired USB, wired Ethernet, wireless Ethernet ) and TIS2web.It is with 30 languages available to choose,and support with wifi,but now you need to buy wifi card or you have the wireless card yourself.
Recommended setup and configuration:
? Place the Techline PC next to or inside the vehicle (if it’s a Techline laptop computer).
? A laptop computer should be plugged in to ensure the laptop battery will be maintained during the programming event.
? Connect the PC to the Internet/TIS2Web via a quality LAN cable or reliable Business Grade Wi-Fi access point.
? Connect the PC to the Multiple Diagnostic Interface (MDI) using the USB cable method.
? Connect a Midtronics? GR8 (Essential Tool EL-50313), set up in Power Supply Mode, or an approved Midtronics? PSC 550 Battery Maintainer (SPS Programming Support Tool EL-49642) or equivalent to maintain proper battery voltage during programming when required.
? To ensure the computer remains active, adjust the Microsoft Windows? “Power Options.” Select the “High performance” power plan and set it to “Never” sleep in either ‘On Battery’ or ‘Plugged In’ modes.
2.Recommended Process Rationale
During SPS programming, the required data/calibration files are retrieved from the TIS2Web server. They are downloaded completely, verified and cached onto the Techline PC before module programming can begin. When ready, programming continues using these cached files and the required data is then transmitted from the PC to the vehicle module by way of the Auto key Programmer MDI and DLC.
If an error or connection problem occurs during file retrieval, it may be necessary to restart or recover and carry on retrieving the required files. If a communication error develops while transmitting to the vehicle, there is a risk of damage to the vehicle module that may be unrecoverable. Because of this, a USB connection from the Techline PC to MDI from www.cnautotool.com is a best practice.
