      "I just plugged my AutoSync in for the first time on my 2017+ K2xx (IO5/IO6 radio) vehicle and when I try to open the AutoSync menu, the screen is blank"

      2017+ vehicles have a Serial Data Gateway Module that blocks display messages from the AutoSync. You can either buy the plug-and-play harness (CLICK HERE) or you can do the wiring mod yourself.

      It is highly recommended to buy the harness to make the job much easier, however if you are comfortable with wiring and swapping pins on connectors, (CLICK HERE) for the DIY. The pins are delicate so please be careful if you go the DIY route

      ======================================================

      "I did the SDGM wiring/connector bypass modification on my 2017+ truck and now the instrument cluster gauges are dead and I have warning lights on"

      The SDGM bypass mod was not done correctly, or a pin got broken/bent, or one of the SDGM connectors isnt fully seated. Remove the SDGM connector and make sure none of the pins are broken/bent.

      ======================================================

      "The menus dont come up on my 2019+ T1xx pickup truck, 2019+ Colorado/Canyon, and I cant find the SDGM under the dash".

      The AutoSync does NOT support on-screen-menus on T1xx (2019+ 1500 pickup truck, 2020+ HD pickup truck) and 2019+ Colorado with the next-gen infotainment system. The AutoSync on-screen-menus only work on vehicles with the IO4 / IO5 / IO6 infotainment system (check your glovebox RPO code sticker)

      =======================================================

      "The turn signal backup camera doesnt work, it just comes up as a blue screen"

      THIS IS BY FAR THE MOST COMMON QUESTION. You need to do the tailgate camera wiring harness modification (YouTube link below), OR you can buy a pre-made plug-and-play harness (CLICK HERE).

      YouTube DIY explaining the tailgate backup camera wiring modification: https://www.youtube.com/watch?v=nB-QMF7z_WY&t=119s

      THIS IS NOT THE SAME HARNESS MOD AS THE SDGM HARNESS MOD MENTIONED ABOVE. This is to do with the backup camera/tailgate wiring harness.

      =======================================================

      "How do I register my AutoSync?"

      You must create an account at https://autosync.btdieselworks.com/ and register your AutoSync. NOTE: the AutoSync portal is a COMPLETELY DIFFERENT website than this website you are on now (www.btdieselworks.com)

      The easiest method for registering your AutoSync is simply to just scan the QR code on the AutoSync sticker with your phone.

       ========================================================

      "I dont see my AutoSync on my account page"

      First, be sure you are on the correct website (https://autosync.btdieselworks.com/), and then be sure that you have setup your AutoSync correctly and paired it to your home WiFi network. The AutoSync instructions explain the WiFi pairing/setup procedure.

      NOTE: You only have to do the WiFi setup procedure with your phone ONE TIME. After the initial setup, the AutoSync will save your WiFi network name/password from then on.

      ========================================================

      "I dont see my vehicle on my AutoSync profile page"

      If you have just setup your AutoSync for the first time, your vehicle may not appear right away on your profile. The AutoSync has to do a WiFi server update after it has already been plugged into the vehicle, in order to send in the vehicle info and create it on your profile.

      ========================================================

      "The AutoSync firmware update isnt working, or freezes"

      If the in-vehicle firmware update procedure doesnt seem to work, gives an error, or freezes up, it most likely means that the WiFi signal is too weak. Take the AutoSync inside your house near your WiFi router, and plug it into USB power to do the "offboard update". You do not need to plug the AutoSync into a laptop, it only needs power...a USB phone charger cube works fine.

      ========================================================

      "Im trying to update my BCM tunes and it says 'rate limit exceeded' on the screen"

      There is a certain variable daily/monthly limit on how many times you can download new/updated BCM tunes (to reduce server load/abuse). It is best to preset ALL of your BCM tune settings/configurations at once, so you only have to do one tune file download/reflash. If you get the rate limit exceeded message, please wait 24 hours and try the download again.

       ========================================================

      "Im flashing my EBCM (ABS module) tunes and I get the "Error: 17 -- Step: 14" message"

      Not all EBCM tune settings are compatible with all EBCM operating systems/software. This error means that you have selected a tune option/setting that is incompatible with your particular truck.

      I have tried my best to disable individual settings for specific trucks that have known incompatibilities, however due to the huge number of vehicles/software combinations, some get missed. Be sure to thoroughly read all of the tune setting descriptions to make sure there are no compatibility notes that might apply to your vehicle. Carefully review ALL of the changes you have to the ABS module tuning, fix any errors, and try the download again.

      ========================================================

      "The AutoSync menu only comes up with the key on engine off (K2xx)"

      The key on engine off, and engine running methods for activating the AutoSync menu are different. Key on engine off: cruise control CANCEL button. Engine running: press the rear defrost button 4x in a row.

      ==========================================================

       "I was in the middle of flashing my BCM and the AutoSync got unplugged, or the flash failed, and now my truck wont start"

      The AutoSync has a special BCM recovery mode for these situations. DO NOT cycle the ignition off. Unplug the AutoSync. Press and hold the accelerator pedal to the floor, and while holding it, plug the AutoSync in. Keep holding the accelerator pedal (you will see the LED on the AutoSync flash red/blue/etc). After a minute or two, the LED on the AutoSync should flash rapid-blue, and the truck should come alive again and all of the instrument cluster warning messages should disappear. Release the accelerator pedal and cycle the ignition off for 30 seconds.

      You can now retry the modified-tune BCM flash again. If it fails a second time the same way it did the first time, contact support. DO NOT keep retrying the flash.

       =========================================================

      "I bought a used AutoSync, what do I do"

      First, create an account at https://autosync.btdieselworks.com/, be sure to enter your AutoSync serial number (or scan the QR code on the AutoSync). Plug the AutoSync into your truck and verify everything is working properly. DO NOT CONNECT THE AUTOSYNC TO WIFI YET.

      Contact us (support@btdieselworks.com) and let us know that you bought the AutoSync used and want to transfer it to your new account. We will transfer it, and once thats done, you can then do the normal WiFi setup procedure explained in the AutoSync instructions. Once the WiFi has been setup, you should see your vehicle and AutoSync on your account portal at https://autosync.btdieselworks.com/. NOTE: When doing the WiFi setup procedure on a used AutoSync, it might take longer (up to 1 minute) for the WiFi network "AutoSync" to appear on your phone.

       ==========================================================

       "Can I use the AutoSync on multiple vehicles"

      Yes! You can use the AutoSync on as many vehicles as you want, as long as the AutoSync is the proper model for the vehicle (for example a 2007-2014 AutoSync will not work on a 2016 truck). Keep in mind that 2017+ IO5/IO6 vehicles require the SDGM bypass harness/wiring mod, so if you are swapping the AutoSync between two 2017 vehicles, they will both need to have the SDGM mod done. You can leave the SDGM mod permanently installed in the vehicle, even if the AutoSync is unplugged.

      BCM tune licenses are tied to a VIN and will not transfer between vehicles.

      One AutoSync can tune multiple BCM's, however you will have to buy an additional BCM tuning license for each vehicle.

      ==========================================================

      "I changed my home WiFi name/password, how do I reset the AutoSync?"

      There are two methods of resetting the WiFi credentials: in-vehicle, and offboard. The in-vehicle method only works on GMT-900 and K2xx (with IO4/IO5/IO6 radio) vehicles. The offboard method works on all vehicles.

      K2xx: Go into the AutoSync main menu -> Page 3 -> "AutoSync Info". Pull back the turn signal lever to the flash-to-pass position and hold it. Within a few seconds, the "Firmware Update" button will change to "Reset WiFi". Keep holding back the turn signal lever, and press the "Reset WiFi" button. The AutoSync should then jump to the firmware update page (release the turn signal lever), and you can setup the WiFi the same way you did when the AutoSync was new (search for the AutoSync WiFi network with your phone, connect, open your phone web browser and go to the website 10.10.0.1)

      GMT-900: Go into the AutoSync config menu (cruise control on, press and hold the cruise+ and tapshift+ buttons together for a few seconds), then use the tapshift buttons to scroll to the page that says "Firmware Update". Then pull the turn signal lever back into the flash-to-pass position and hold it, the "Firmware Update" text should change to "Reset WiFi". Press the Cruise RES+ button and then the AutoSync will jump to the firmware update page (release the turn signal lever), and you can setup the WiFi the same way you did when the AutoSync was new (search for the AutoSync WiFi network with your phone, connect, open your phone web browser and go to the website 10.10.0.1)

      Offboard (AutoSync-G2 only): Start with the AutoSync unplugged. Press and hold the "A" button on the AutoSync (the button closest to the USB port). While holding the button, plug the AutoSync into USB power. Keep holding the button. Within a few seconds, the LED will turn red. Keep holding the button. Within 5-10 seconds, the red LED will begin to flash. Keep holding the button. After a few seconds of flashing, the LED will go back to solid red. Release the "A" button, unplug the AutoSync for a few seconds. Then plug the AutoSync back into USB power, and within 10 seconds the AutoSync LED should turn green, indicating its ready to be paired to a new WiFi network. Then you can setup the WiFi the same way you did when the AutoSync was new (search for the AutoSync WiFi network with your phone, connect, open your phone web browser and go to the website 10.10.0.1)

      ========================================================

      "I purchased BCM tuning, how do I get it onto my vehicle?"

      First, login to your AutoSync web profile at autosync.btdieselworks.com. Then select the VIN of the vehicle you want to tune. Make sure that the BCM tune status says "Licensed - Ready". If the BCM tune status says "Licensed - Not Ready", check back again in 24-hours. If it still says not ready, contact us via email.

      Lower on the page, you will see the dropdown menus for all of the BCM tune settings/adjustments. Go through all of the settings and be sure to read the descriptions carefully before changing a setting. Make all of your desired changes and be sure to hit the green "create" or "update" button each time you make a change to the values.

      After you have made all of your desired changes, do the firmware update procedure on your AutoSync. The BCM tuning is now downloaded onto the AutoSync, but it is NOT downloaded into your vehicle yet.

      To flash the tuning into the BCM, first turn the ignition ON engine OFF and wait 20 seconds or so for the AutoSync to read vehicle info and verify licenses. For vehicles with push-button-start, press and hold the start button for several seconds with your foot OFF the brake pedal.

      GMT-900: Go into the AutoSync config menu (cruise control on, press and hold the cruise+ and tapshift+ buttons together for a few seconds), then use the tapshift buttons to scroll to the page that says "Module Programming". Press the cruise control RES+ button. Use the tapshift buttons to scroll to "BCM Reprogram". Press the cruise control SET- button to flash the modified tune. The flash will take roughly 20 seconds, and then ask you to cycle the ignition off. All done!

      K2xx (or any other vehicle with the IO4/IO5/IO6 radio): Go into the AutoSync main menu. Go to Page 4, then "Module Programming". Select "BCM Programming". Then select "modified" to flash the modified tune. The flash will take roughly 30 seconds, and then ask you to cycle the ignition off. All done!

      Vehicles without AutoSync on-screen menus (T1xx, 2019-23 Colorado, etc): Pull the turn signal lever back to the flash-to-pass position and hold it. Press the brake pedal and hold it. Press the drivers door LOCK button. Wait a few seconds, and the LED on the AutoSync should start rapid flashing red/blue, and the instrument cluster will show a bunch of warnings etc. After about 30 seconds, the flash should complete, the warnings and lights on the instrument cluster will clear, and the LED on the AutoSync will be quickly flashing BLUE only. You can then release the brake pedal and turn signal lever, and cycle the ignition OFF. All done!

      ==========================================================

      "I purchased BCM unlock, how do I get it onto my vehicle?"

      The BCM UNLOCK is not the same as BCM tuning! BCM unlock is only for 2017+ vehicles to allow use of strobe/work lights with engine running, windows close from keyfob, and SecurIdle. BCM TUNING is what allows you to make all the custom changes to remote start timer, headlights, door locks, etc.
      First turn the ignition ON engine OFF and wait 20 seconds or so for the AutoSync to read vehicle info and verify licenses. For vehicles with push-button-start, press and hold the start button for several seconds with your foot OFF the brake pedal.

       

      K2xx (or any other vehicle with the IO4/IO5/IO6 radio): Go into the AutoSync main menu. Go to Page 4, then "Module Programming". Select "2017+ BCM Unlock". The procedure will take a few seconds, and then ask you to cycle the ignition off. All done!

      Vehicles without AutoSync on-screen menus (T1xx, 2019-23 Colorado, etc): Pull the turn signal lever back to the flash-to-pass position and hold it. Press the brake pedal and hold it. Press the accelerator pedal to the floor and hold it. Press the drivers door LOCK button. Wait a few seconds, and the LED on the AutoSync should start rapid flashing red/blue, and the instrument cluster will show a bunch of warnings etc. The unlock procedure should only take a couple of seconds to complete, then the warnings and lights on the instrument cluster will clear, and the LED on the AutoSync will be quickly flashing BLUE only. You can then release the brake/accelerator pedal and turn signal lever, and cycle the ignition OFF. All done!

      ==========================================================

      "Im trying to use the strobe lights and work lights and it says 'Strobe Lights Not Avail.' Also, windows closed from keyfob and SecurIdle dont work"

      2017+ vehicles require purchasing the BCM unlock (CLICK HERE) to allow use of strobe/work lights with engine running, windows close from keyfob, and SecurIdle.
