BT DieselWorks AutoSync G2 – Installation guide

THESE INSTRUCTIONS ARE ONLY FOR THE NEW AutoSync "G2"

Requires IO4/IO5/IO6 radios (check glovebox RPO sticker)

Does not work on IO3, IOB, IOR, IOT (or any of the T1xx new body style pickups)

2014-2018 Silverado/Sierra 1500 pickup

2015-2019 Silverado/Sierra 2500-3500 pickup

2015-2020 Tahoe/Yukon/Suburban/Escalade SUV

2015-2018 Colorado/Canyon pickup

And many other 2014ish-2019ish GM cars with IO4/IO5/IO6 radio

Thank you for purchasing the BT DieselWorks AutoSync. The AutoSync is a patent-pending revolutionary

new easy-to-install module that adds many enhanced functional and comfort features to many GM late

model vehicles. Please be sure to also follow the quick-start guide on the 'AutoSync installation guides'

page on our website. It is VERY important to register your AutoSync and pair it to your WiFi as soon as

possible to validate warranty and receive the latest firmware updates and new feature additions.

I know these instructions are long/boring, but PLEASE try to at least glance over every page

first. 95% of tech support email/questions we get are simply due to misunderstanding/not

reading the instructions. 

NOTE: 2017+ vehicles have several feature limitations and also require one additional minor wiring

change under the dash at the Serial Data Gateway module connector. Please see the additional 2017+

supplement document instructions on our website on how to perform this wiring change/pin swap.

NOTE: We now offer a plug-and-play SDGM bypass harness to make the installation extremely easy on

2017+ vehicles. This harness installs in less than 2 minutes and negates the need to do the old

wiring/pin swap. The wiring/pin swap can be tricky, and the pins are quite fragile...the SDGM harness

is less than $10 and will potentially save huge headaches:

Page 3 On the AutoSync, there two momentary push-buttons on the side of the module marked “A” and “B” (not normally used), and two status LEDs. The AutoSync must remain plugged in at all times for features to work. You can use AutoSync with an OBD port splitter (to use simultaneously with another scan tool, Edge Insight, EZ Lynk, etc), however compatibility is NOT guaranteed unless you use the BT DieselWorks OBD splitter, available at our website.

Simply tap whichever tune you want to switch to, and the DSP/SOTF mode will immediately be changed. The currently selected tune will be highlighted with a “( )”...
Page 6 Work Lights – Found on page 1 of the AutoSync main menu. This activates exterior work light mode. Work light mode manually turns on all cargo/bed lighting, as well as reverse lights. This feature is useful for illuminating the rear of the vehicle at night, hooking up trailers at night, checking on cargo, etc. 2017+ vehicles have the same limitations as mentioned above for the strobe lights feature.
Page 7 The “Minimize” icon will shrink the live engine data display to a small bar along the bottom of the screen. This is helpful for keeping essential data at a glance, while still being able to view the navigation map, radio controls, etc. Due to the smaller size of the “minimized”...

CHECK THE HARNESS MODIFICATIONS BEFORE EMAILING ME SAYING “HEY, THE BACKUP CAMERA OR TURN SIGNAL CAMERA FUNCTION DOESN’T WORK!”...

Page 12 AutoSync must be within range of your WiFi network for this to work and the AutoSync WiFi must be configured manually. If you cannot park your truck within WiFi range, use the “offboard” update procedure, explained in the separate AutoSync Quick-Start guide.

See top of page 6 for details! -DRL override. If you have purchased BCM tuning add-on, do not touch this and be sure its set to stock. If you have a 2014-2016 truck and want to manually adjust the Daytime Running Lights, you can use this option.
Page 14 -Engine Data Acquisition mode. There are two different methods of polling the ECM to read live data. Dynamic is preferred because it allows faster data reading/display, however it might have compatibility issues if you are using the AutoSync on an OBD splitter with another scan tool (Edge CTS, Ez Lynk, Banks etc).
Page 15 Other Hidden AutoSync Features Window control – This function allows you to open and close the side windows via remote keyfob.

Locate any regular phone charger or power supply, be sure it is capable of supplying at least 1-amp or 1000mA. Note: if you have also purchased additional BCM tuning separately, this “offboard update procedure”...
