The Techline Customer Support Center (TCSC) has released their latest tips for Techline Connect and the Service Programming System. To get the most out of Techline Connect (TLC), check the following items when using the application. Be sure to verify these operating features and requirements before making a call to the TCSC<\/p>\n

The Techline Connect installation link is available for download in GM GlobalConnect. (Fig. 6)<\/p>\n

TECHLINE CONNECT CORE APPLICATION<\/strong><\/p>\n

PC Specs<\/strong><\/p>\n

Ensure the PC (personal computer) meets the minimum specifications or better as defined by the latest GM Dealer Infrastructure Guidelines (DIG). The guidelines outline the dealership technology needed to ensure reliable data communications for all dealers, including recommended PC specs.<\/p>\n

To view the latest DIG (U.S.) as well as PCs for purchase, go to gmdesolutions.com and select the Dealer Services tab. Once you\u2019ve input your BAC and zip code, select Techline IT Solutions from the Dealer Services menu. In Canada, the latest DIG can be found in the Dealer Security and Information Technology App on GM GlobalConnect.<\/p>\n

Performance Issues<\/strong><\/p>\n

If the PC meets the specs for running TLC, many times performance issues can be solved by a PC reboot, or an uninstall and reinstall of Techline Connect.<\/p>\n

Local Admin Rights<\/strong><\/p>\n

Run Techline Connect as an Administrator for the latest updates. (Fig. 7) All Techline application updates and installations must be performed from an account with local Windows administrative rights. Firewall exceptions should be made for the Techline Connect application.<\/p>\n

The DIG includes a list of how to configure Techline Connect to have the elevated privileges necessary to ensure the application updates are received, downloaded and installed properly. Also refer to the Techline Connect Setup for Updates PDF on TechLink for additional instructions.<\/p>\n

Authenticate User Error<\/strong><\/p>\n

If an \u201cUnable to Authenticate User” error occurs, ensure that the ID can successfully log in to GM GlobalConnect. If the ID is locked in GM GlobalConnect, the Techline Connect log in will fail.<\/p>\n

If the user can log in to GM GlobalConnect without issue, reboot the PC and attempt to log in again to Techline Connect.<\/p>\n

 <\/p>\n

SERVICE PROGRAMMING<\/strong><\/p>\n

Be sure to follow all appropriate Service Information when programming any vehicle, including control module references, DTC diagnostics, Bulletins and Field Actions. Do not program a control module unless directed to be a service procedure or Bulletin. If the control module is not properly configured with the correct calibration software, the control module will not control all of the vehicle features properly.<\/p>\n

Confirm the VIN<\/strong><\/p>\n

Technicians can manually enter the VIN for a vehicle being serviced via \u201cSelect Vehicle,” followed by entering the VIN on the left side of the TLC screen. Always verify that the VIN displayed in the TLC left-side drop-down menu and the top-center window match the VIN plate of the vehicle to be programmed prior to using Service Programming System 2 (SPS2) for programming or reprogramming a module. (Fig. 8)<\/p>\n

 <\/p>\n

 <\/p>\n

For the TLC application, make sure that the power mode (ignition) is ON before reading the VIN from the vehicle\u2019s VIN master module and that a VIN that is already in the TLC application memory from a previous vehicle is not selected.<\/p>\n

TLC implemented a change that has SPS2 always check that the VIN that TLC is set to matches the VIN read from the VIN master module (for example, the ECM for VIP vehicles). This is to address the potential for an incorrect VIN being set in TLC. If the vehicle VIN does not match, a warning message will be shown. (Fig. 9)<\/p>\n

 <\/p>\n

Tech2 Programming<\/strong><\/p>\n

Technicians are able to program via Tech2 in SPS2 by selecting \u201cManually Select Tool” followed by selecting the applicable programming method in SPS2.<\/p>\n

Battery Voltage<\/strong><\/p>\n

Battery voltage must be 12.5v or higher when programming any vehicle. Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will interrupt programming. Install a GM Authorized Programming Support Tool to maintain system voltage. Refer to www.gmdesolutions.com<\/a> for more information. If not available, connect a fully charged 12\u2009V jumper or booster pack disconnected from the AC voltage supply. Do not connect a battery charger.<\/p>\n

Hardwired Connection<\/strong><\/p>\n

An MDI or MDI 2 hardwired connection from the PC to the vehicle ensures successful programming on newer architecture vehicles.<\/p>\n

Do not download or install the files wirelessly. If there is an interruption during programming, programming failure or control module damage may occur.<\/p>\n
