ELM327 OBD2 USB Adapter for Windows, ELMconfig Scanner with MS CAN/HS CAN Switch for Scan F150 F250 Car and Light Truck Check Engine Light, Diagnosis on Windows with V1.5 Chip

The OBDMONSTER scanner has been a game-changer for diagnosing issues on my vehicle. It’s compact, easy to use, and connects quickly without any hassle. The interface is straightforward, and it provides clear, accurate codes with descriptions, which makes troubleshooting way easier—even for someone who isn’t a mechanic. I’ve used it to reset check engine lights, monitor real-time data, and verify repairs, and it’s worked flawlessly every time. For the price, the quality and functionality are unbeatable. Highly recommend for any DIYer or car enthusiast looking to stay ahead of maintenance.

After adding ~30 wires from my trunk to front end through the lower trim panels in my 2009 Fusion for a stereo, rear camera and additional accessories install; I was left with an airbag light ON after starting my car. At first I figured it was probably the passenger side impact sensor for the air bags, as that is located behind the lower-middle trim piece on the passenger side that was removed during the install. Reseating this connector and cleaning with clean contact cleaner seemed to fix it but it came back shortly after.A little research on the net showed that Ford controls the airbags mainly through the RCM (Restraint Control Module). From what I could tell, a normal scan tool with the added SRS airbags function wasn't going to give me the info I needed to locate the fault. I almost purchased one of the higher end Chinese scan tools but found this.After installing the drivers and the downloading the app, I had issues getting it to "connect to my vehicle" though the app's status showed the USB-to-OBD2 connection was working and device manager on Windows 10 showed the driver/adapter was being detected. I troubleshot a little, and found that they mention using the Windows compatibility mode for Windows 10, but that didn't seem to help. After another 10 minutes I noticed it wasn't seating as easily as my cheap ODB2 scan tools and found some plastic blocking it seating all the way. Bingo!Once connected to my vehicle the software read my HS-CAN bus, showed all it's modules, then asked if I had a "switch" on the controller and after flipping it then read my MS-CAN bus. It showed a B2295 fault on my RCM. An internet search then showed this is related to the seat mounted passenger airbags, but didn't tell which one. Using the scan tools "PID data" option I was able to select 4 PIDs related to the seat airbags, "P_ABAGR2", "PS_AB", "DS_AB" and "D_ABAGR2". These showed the real-time feedback resistance in ohms on the these circuits. Airbags should be over 0.9 ohms to ~4.3ohms to not cause RCM faults in my model. I found the PS_AB to be 5-7 ohms depending on seat position and articulation. So I removed fuse #25 to disable the RCM and pulled the airbag from the side of the seat. I then sprayed the contacts with cleaner and scrubbed them. I managed to get the connector a little more slack in the seat and bingo, 3 ohms no matter how the seat is articulated. The one of the wires looked a little strained but I didn't have the OEM airbag side connector so I didn't want to cut and solder it. I'll do that at a later date if needed, this scan tool allows me to check it anytime in the future.This thing saved me a ton of money and I wouldn't have suspected the fault being in the seat because I wasn't messing with it when the fault occurred; that would have been far down the troubleshooting flow chart. After the initial issues with the OBD2 port fitment, the thing works like a champ anytime. Hopefully someone might find this helpful!

This cheap little device is just straight awesome! For it being cheap it works perfectly! I got it to work with forscan & my Ford escape. It does not disappoint. I was able, despite the warning on forscan that its not supported, to get it to communicate and do any and everything I want. It's like have it hooked up to the dealership computer. Can read and clear codes not just the check engine light but also other codes that don't show up on standard scanners! I can't recommend this enough specially if your using with forscan but don't want to spend a lot more money on the OBD2 readers that are supported!

I wanted this to hack on for an electronics project and I didn't care about the USB functionality at all. I just wanted a simple way to directly interface with the ELM327. I was afraid that the unit would be like other "ELM327" clones that place the microcontroller under blob of black epoxy, making it hard to interface with.Fortunately, this unit comes with a Microchip PIC18F25K80 (which is what the real ELM327 should be using). Whether it's flashed with the real firmware is unknown, but it behave identically enough for all my use cases.In the photo, the largest chip in the center is the PIC18F25K80. The SOIC-8 chip above it is a CH340, which a USB-to-serial translator. The SOIC-8 in the top-right is a SIT1040, which is a CAN transceiver. I believe the random assortment of FETs and resistors in the bottom right are for the ISO-L, ISO-K, and J1850 buses.Of note, there are no voltage regulators in the unit as it takes 5V directly from USB. For my use cases, I'll essentially be de-soldering the CH340 and connecting a custom-built board into the 5V, GND, TX, and RX lines.EDIT: The voltage reading is inaccurate by about 0.2V. The circuit here differs from the recommended circuit in the ELM327 datasheet in that there is a Schottky diode between the Vbat and the ELM326's ADC. The diode has a voltage drop between 0.15V to 0.25V. I guess the diode provides extra protection, but it affects voltage reading accuracy. If you feel inclined, you can desolder the diode and put a bridge wire in its place.

The media could not be loaded. This is a very good adapter and yes. It works with for scan I love it, only issue is that the bus switch isn’t automatic although other than that 10/10. Personally disabled double beep on leaving vehicle as well as monitored knock on a sensor oscilloscope for my 2019 Mustang.

Works with Forscan like it claims ,though the program says its not quite compatible and some features may not be available, I havnt found any feature unavailable for me yet. I use it with Forscan for my 2013 F-150 Ecoboost XLT which does need the MS/HS switch that this adapter has. Maybe some newer or different Ford vehicles need a different adapter for use with Forscan but this one worked for me.

I was not able to get this to work. The driver could not be downloaded from Chinese website. My antivirus software said it was a dangerous website with possible malware. No response to emails. The supposed manufacturer doesn't mention this product on their website, and no response to email there either.

This works great with ForScan on 2022 Ford Maverick Lariat. However, the switch is a pain.Get the non-switched version. Probably worth the extra few $$
