ELM327 OBD Bluetooth Diagnostic Module That Can Scan Other Modules Such As ABS, BCM, TCM?

BlaineBug · April 30

I have owned a cheap ELM327 OBD2 Bluetooth diagnostic module that I have used and continue to utilize in conjunction with the Torque Lite app for about 7ish years now. Works great! Recently I downloaded a few more diagnostic apps to branch out and test in line with my new 1099 intendent contractor work which involves inspecting used vehicles, one of these apps which is called CarScanner. This app has the ability to scan additional modules beyond OBD codes, which includes the body control module, transmission control module, airbags, etcetera amongst various other modules too (screenshots attached!)

When I attempt to scan any of the other modules beyond OBD, CarScanner reports that my ELM327 dongle is "defective," but rather it means that it is incompatible. I can read OBD trouble codes but cannot read any of the other modules, lest I receive this error about incompatibility or defectiveness.

My question is, what other OBD Bluetooth dongles are compatible with reading these various other modules? I have done a little but of research and have no definitely matter to this question. It seems to me that more of the "appropriate" diagnostic dongles are intended for use with laptops as such and have a USB connection which does me absolutely no good since I am using my Android phone and a Bluetooth connection rather than a laptop that has USB ports.

I am including some screenshots from my phone for reference. If you have any questions, just ask as I am just typing this up real quick!

There are a number of different brands and models available, such as the Veepeak OBDCheck BLE+ Bluetooth OBD2 Scanner, which is specifically designed for use with Android and iOS devices. Other models, such as the Autel MaxiCOM MK808, are USB-based, and may require an adapter for Bluetooth-enabled devices. If you are looking to purchase a more comprehensive solution, there are also professional-grade diagnostic tools that support both Bluetooth and USB connections.

Thank you. I believe I am going to stick with what I have for now as it is more than sufficient for my needs.

However occasionally the CarScanner app has given me the ability to scan differently for certain vehicle models, if I recall it gave the option to scan "unconventional" and has tiers. The next time I am given these additional options I will be sure to take a screenshot.
