  1. The latest time a Battery Chart was published was in 2018. We NOW have 2021 models.
    We need an updated Battery Chart ASAP. Especially when there is so much STUFF on top of the
    batteries, You can se NO Battery CCA or other battery information.
    HELP !!!!!!!!

  2. Some non–DOT-approved LED lamps may not draw enough current for the K68 Trailer Lighting Control Module to detect a trailer when connected and the K68 Trailer Lighting Control Module will not enable the lighting circuits to the trailer. Possible ways to remedy this:

    A. Change one or more trailer lamps on the detectable circuits to incandescent bulbs or DOT-approved LED lamps to increase the current draw, which will maintain full functionality of the K68 Trailer Lighting Control Module. The addition of incandescent bulbs/DOT-approved LED lamps is at the customer’s/trailer manufacturer’s discretion.

    B. A load resistor could be added in parallel to the detectable lighting circuits of the trailer, which will increase current draw. One known source is the Curt brand Trailer Wiring Adaptor, which can be plugged inline with the 7-way trailer connector. The adaptor can be used to simulate additional lighting load, which allows the K68 Trailer Lighting Control Module to detect the trailer, but some circuit diagnostics and bulb outage detection will not be possible. The addition of a load resistor/adaptor is at the customer’s/trailer manufacturer’s discretion.

    Refer to #PIT5747 for more information.

    We are seeing more problems with the new trucks not being compatible with new trailers with l.e.d. lights, owners get very upset when their $70,000 truck will not make the lights work on a new $50,000 trailer they just purchased. They don’t want to hear about the truck “detecting” the trailer before the computer allows power to be sent out to the trailer. They don’t want to pay to have their trailer modified to create a power draw that the truck can detect. I think either the software running this system needs to be updated or an adaptor of some kind built that would sit between the truck and trailer….all plug and play. Make things easier for our customers to use. We are not meeting expectations with this problem at the moment.

  4. Mike Allen says:

    Just curious if there are plans for the EL-50334-20 tester to accommodate the new USB TYPE C ports.

  5. Is there an updated chart for the battery CCA ratings on models past 2018?

  12. What site are you trying to access with the password?

  13. My password no longer works and there is not option to reset password. How do I fix this issue please help??!

  14. Toemah Bowers says:

    Hello I have a question. Other people including myself are always wandering if there’s more wear and tear on the Auto-stop starters? Especially driving in town or a place where frequent stops are made. I am employed at a Chevy Dealership and I’m looking forward to being more knowledgeable about the different Chevy vehicles out on the market. Thank you for your services.

  15. One of the main features of Techline Connect is automatic updates including leases like GDS2. If the GDS2 lease is not updating, its most likely due to restriction of administrative permissions on your PC. To easily check this, right-click the Techline Connect icon and select ‘Run as Administrator’. You should see a green box and check mark at the start up and the lease renew. If the problem persists, let your dealer system administrator know. You can also contact the Techline Customer Support Center for help.

  16. COLIN VALIN says:

    WHY DOESN’T TLC AUTOMATICLY UPDATE YOUR GDS2 LEASE WHEN YOU SIGN IN. I HAD TO RE-INSTALL TLC TO UPDATE MY LEASE EVEN THOUGH IT WAS STILL VALID? DID I MISS SOMETHING, DID NOT SEE IT MENTIONED IN THE USER GUIDE EITHER.

  17. Gary Baughman says:

    I appreciate the reference charts, but we need a battery application chart that covers the new models. When doing a PDI battery charge it ask what type and CCA the battery is. There is so much on top of the batteries now that it is impossible to get the information you need from the label on top of the battery.

  18. PLEASE DO A COURSE ABOUT STARTER MOTOR REPLACEMENT ON L5P ENGINES, FOLLOWING SI PROCEDURE IS NOT POSSIBLE TO REPLACE IT.

  19. The rollout of the new Techline Connect application will begin soon. It will be phased in by state throughout the fall. Dealers will receive an invitation to install the new app. The invitation will appear as a tab in TIS2Web and an icon on the TIS home page.

  20. I work at a dealership how can we get on tech line connect subscription

  21. 2019 model year information is being researched. The chart is on schedule to be updated soon. Thanks for your patience.

  22. Norb Balenski says:

    Any time frame on when you will publish updated battery specs for 2019 vehicles

  23. The Remote Left in Vehicle Alert can be turned on or off in the Settings menu on the infotainment screen. Go to Settings > Vehicle > Remote Lock, Unlock, Start > Remote Left in Vehicle Alert.

  24. Bill Woodhouse says:

    Is it possible to disable the horn alert for the “keys left in vehicle” on the2019 next generation Silverado?

  25. Techline Data Service (TDS) has been activated for all GM dealerships. Select the TDS tab in TIS2Web to install and configure the application.

  26. Mohamad Salem says:

    Hi, I was wondering and asking about the TDS programming service on how to get the yearly membership.. do i need an account with you guys? please let me know on how to subscribe to this service.. Thanks!!

  27. Hi im just wondering if you have any pre 2012 oil capacity guides
    thanks

  28. Tomasso Pollardi says:

    As a Sales Manager I found this very informative and passed it along to the Sale Team.
    Thanks

  29. Currently, there is not a hands-on class for the 10-speed transmission. 10-speed transmission training is available in interactive video course #17041.80W. It is not possible to provide hands-on training for all topics. Hands-on training is available for the 8-speed transmissions in course #17041.67H.

  30. When can we expect a hands on class for the new 10 speed trans? My personal opinion is that we the technician should be trained on these new components before they are released for sale. I had to teach myself the 8-speeds off of youtube videos lol. It would make for a more efficient tech to have our hands on something before it is just thrown in our laps to loose time on because it is unfamiliar to us. From what i have read about the 10 speed it is unlike any other trans we have dealt with in the past. The 8-speeds have been out since 2014 and GM still hasn’t resolved the torque converter issue and i dont have much faith in the 3rd fluid redesign to fixing it either.

  31. The 2019 battery information is not yet available. Refer to the latest version of Bulletin #15-06-03-002 for more information.

  32. Norb Balenski says:

    When will the battery charts be updated for 2019

  33. In order to provide the latest up-to-date information, the TechLink archives include only the last three years of publication. For older information, refer to the appropriate Service Information for a particular vehicle.

  34. how do we access archives back to the 2000’s. Valuable information is available in the archives. Tried logging through global connect and couldn’t access archives.

    thank you

  35. The 2019 Impala is in the latest GDS2 Global Diagnostic Package v2018.9.2. You must launch GDS2 from TIS2Web and install the latest diagnostic package.

  36. Steve Riley Jr says:

    i have a 2019 Chevrolet Impala and it is not listed in GDS 2. i have to manually select a 2018 Impala just to get codes. Impala’s are not even in the updated charts. How can i get this corrected as this vehicle has a SES light with COMM issues.

  37. Always check bulletins to ensure you have the latest information. The chart has been updated, based on bulletin 15-06-03-002M. Thanks for your feedback.

  38. Pamela Kreitz says:

    We find a dramatic error in your GM Original Equipment Battery Ratings and Part Numbers versus bulletin 15-06-03-002M . We are always admonished to use the latest bulletin and your chart has a discrepancy with Silverado/Sierra LD/HD .
    This can and WILL effect our claims if our technicians use your chart vs the bulletin, and battery claims are touchy enough. You print the LML/L5P V8 Diesel – HD PU L96 V8/Gas and the V6/Gas should be 730 CCA yet the bulletin is written with 770CCA. WHO IS CORRECT ?? And will corrections be noted where we can ALL SEE them?
