GEARWRENCH Everyday Diagnostic Tool Bluetooth OBDII Tester | GWSCAN

Very solid unit for the price. Initial setup is quick and simple - mine on an Android based phone. Normal Play Store app install and then a few demographic entries for registration and license key activation. First use then goes into vehicle specific data downloads. Expect 5-10 minutes as this unit has compatibility with many vehicles makes and models.Once initial config of the app is done and the unit is plugged into the vehicle OBD port the app connected quickly. Once connected to the unit the app gives you the option of doing vehicle specific diagnostics either automatically or manually. The auto detect function worked well for multiple vehicles - BMW, 2015 and 2024 Subarus. Speed of the diagnostic scan depends on the actual vehicle as each of mine varies but all were extremely fast when compared to my other scanners (hardware and software based). The initial scan auto detects VIN, make, model, etc. and then scans all of the vehicle's available modules. Once scanned you can view a large amount of module parameters and states. A few examples - for the 2015 Subaru it was stated on a different forum that the GW tools do not have CVT fluid temp, which is key to proper filling procedure. Well, I can confirm that it does w 1/10th degree resolution. While I was in there, I was able to read and clear all errors across many modules. While in the transmission module, the BT unit has a broad number of good monitors for many different states (e g., shows live state of each gear) and a nice feature is it gives the normal value ranges for the numeric monitors. Just to check, I went into a few other modules and was please to see the same broad range of monitors (for example, live state of brake light switch) which makes troubleshooting and ruling out certain components so much easier. Unlike other scanners, you don't have to setup a data display screen to see every value. You do have the option to monitor the value trends and then generate a report. For the BMW, it actually has BMW error codes vs P codes and a large number of diagnostics when compared to my other BMW specific scanner. The unique item I wanted to try was the FCA Autoauth function which allows you to bypass the firewall on newer FCA vehicles (e.g., Fiat, Chrysler, Ram, etc.). Tried the unit in my 2019 Ram 1500 - unit auto prompts to enter an Autoauth account - I was able to quickly login w my Autoauth account and it was able to get through the secure gateway to do full diag and actuation - this is a big bonus.Aside from diagnostics, the unit has a robust set of functions that you can perform (of course these are vehicle specific). As an example, with a button push or two I was easily able to place the emergency brake in maintenance mode on all my vehicles with this unit.All in all, a pretty decent unit for the money especially for multiple makes. Of course this does not do what it isn't designed for - so it is not a programmer and doesn't claim to be. So for those with dealer lever tools (like ISTA for BMWs) this won't give you module layouts, troubleshooting plans or maintenance plans - but what it advertises itself as it did an exceptional job across my 4 different vehicles.

As a Toyota/Lexus Master tech, I love this thing! Was not sure of the wireless aspect of it as I’ve tried other wireless OBD Bluetooth Scanners that were horribly slow but this one is actually pretty fast! A full vehicle health scan only takes about a minute or 2 depending on how many ECUs the vehicle has. Pretty standard DTC read and clear. Live data is actually pretty good with many PIDs, Search feature, Custom Data list and even graphing! The real impressive thing is the Bi-Directional support this thing is capable of! Compared to the Factory Scan Tool, does pretty much everything (ECM Active Test, Main Body Active test ETC….) the factory one can do. It connects and performs the active tests pretty much instantly! The Special Function seems pretty good especially the TPMS reset/relearn feature, haven’t tried it yet but will try it out.This is only my first impressions on my Toyota Lexus Vehicles but so far I’m very pleased with it. The fast wireless, small and portable, feature packed, compatibility and support, ease of use at this price point makes it a VERY good choice. Definitely great for DIYers or having for emergency situations.

One star for now. Have to finish updating the device but so far...I bought this to work on an 02 Chevy Venture that has an abs light on. It pulls the code fine, but the service information tells me to perform an automated test after clearing the code. Well this device will not clear the code even though it claims to successfully clear the code. Strike one. It does not have the option of performing "automated test" i can only manually activate relays and solenoids in the abs system. Since service manual is non- specific on what to test with the automated test this tool is no good here. Strike 2.See what happens the next time the headlight warning light comes on on my wife's 24 crosstrek. That could end up saving this tools bacon, but I'm not holding my breath...Almost forgot, on Samsung Galaxy A54 the software overseas the display, and there is no way to scroll. It also will rotate to portrait mode. The tablet i wanted to connect it to is too old.
