OBDMATE OM901 OBD2 Scanner Review
The OBDMATE OM901 is aimed at drivers who have outgrown a basic check-engine code reader but do not need a tablet-style professional scan tool. It reads and clears faults in four major systems—engine, ABS, SRS/airbag, and transmission—while also providing live data, I/M readiness, freeze-frame information, O2 and EVAP tests, battery-voltage checking, and a DLC-pin test. Its biggest appeal is simple: it adds useful multi-system diagnostics without subscriptions or a phone app.

First Impressions
The OM901 feels more like a dedicated garage tool than a cheap code reader. It measures roughly 195 × 90 × 34 mm and uses a bright yellow housing with a silicone protector, making it easy to find in a tool chest and less vulnerable to routine bumps. The hard case is a meaningful inclusion because the attached diagnostic lead and scanner can stay together instead of floating around the trunk.
Setup is straightforward: connect the 16-pin plug and the scanner draws power from the vehicle. There is no Bluetooth pairing, account creation, or battery to charge. The 3.5-inch color screen is substantially easier to read than the small monochrome displays found on entry-level readers.
Performance and Feel
The main reason to buy the OM901 is its four-system access. A basic reader usually stops at emissions-related engine codes; the OM901 can also enter ABS, airbag/SRS, and transmission modules on supported vehicles. That makes it more useful when a used car has an ABS or airbag warning that a $30 reader cannot explain.
Live-data graphing adds diagnostic context beyond simply displaying a code. You can watch supported sensor values change, check freeze-frame data captured when a fault occurred, and run the one-touch I/M readiness screen before an emissions inspection. The dedicated handheld controls are also useful with greasy hands or in cold weather, where a phone interface can be awkward.
Buyer feedback is mostly positive on speed and readability, although some owners report that the enhanced “Diagnose” database may require an update for newer or less-common vehicles. That makes compatibility checking important before purchase. For a broader explanation of where this type of tool sits, see this OBD2 scanner vs. code reader guide.
Live Data, ABS/SRS Access, and Electrical Checks
The OM901’s most useful secondary strength is the combination of multi-system live data and basic electrical checks. ABS and SRS faults often need more context than a stored DTC, and the ability to view data streams can help confirm whether a sensor reading looks plausible before parts are replaced. The scanner also displays vehicle battery voltage and can test voltage at the DLC pins, which is helpful when communication problems may actually come from low voltage or a damaged diagnostic connector.
It is still a diagnostic tool, not a bidirectional scanner. It cannot command a fuel pump, cycle an ABS solenoid, actuate a fan, or perform the deeper active tests available on higher-end tools. For more options focused on brake-system data, the site’s OBD2 scanners with live data for ABS diagnostics guide is a useful next step.
Durability
The OM901 has two practical durability advantages: no internal battery to age and a protective silicone sleeve plus hard carrying case. Its specified operating range is 32–140°F (0–60°C), with storage from -4–158°F (-20–70°C). The corded design is less convenient than wireless scanning, but it also removes pairing issues and charging cycles. The manufacturer lists a three-year quality warranty, while free software updates improve its useful life as coverage files are revised.
Value for Money
At roughly the $110 price level seen in current listings, the OM901 sits well above basic engine-only readers but below many all-system or bidirectional scanners. The value comes from adding ABS, SRS, and transmission access, a larger color screen, live graphing, a case, and free updates without a subscription. If you only need check-engine codes, it is overkill. If you regularly diagnose multiple warning lights, the extra system access can justify the jump.
Comparison to Similar Competing Products
The closest comparison is the FOXWELL NT604 Elite. FOXWELL also covers engine, ABS, SRS, and transmission, includes AutoVIN, live data, battery-voltage checking, and lifetime updates. It is typically priced higher, around $139 direct from FOXWELL, but it has a more established four-system platform.
BlueDriver takes a different approach: it is a Bluetooth adapter that uses a phone app and provides enhanced codes, live data, repair reports, and manufacturer-dependent ABS/airbag/transmission access. It is more convenient for people who like app-based diagnostics, while the OM901 is better suited to buyers who want a self-contained screen and buttons.
The Innova 5610 is a major step upward in capability and price. Innova lists bidirectional system tests, OEM live data, service functions, and broader all-system features, but its price is several times higher. Buyers comparing these tiers may also want the site’s full-system OBD2 scanner guide.
Pros and Cons
Pros
- Reads and clears engine, ABS, SRS, and transmission faults.
- 3.5-inch color display with live-data graphing.
- Battery-voltage and DLC-pin testing add electrical troubleshooting value.
- No phone, battery, or recurring subscription required.
- Hard case, silicone protection, USB-C cable, and free updates included.
Cons
- No bidirectional active tests or component actuation.

- Some owners report needing updates or support for newer vehicles.
- Manual and menu structure are less polished than premium scanners.
Who Should Buy This?
The OM901 makes the most sense for home mechanics, used-car shoppers, and owners who want to investigate ABS, airbag, transmission, and engine warnings without paying for a professional tablet. It is also a strong fit for people who prefer a wired handheld device over a phone app. If you are inspecting used vehicles, compare its capabilities with this roundup of OBD2 scanners with ABS and SRS for used-car buyers.
Skip it if your work requires actuator tests, coding, key programming, ABS bleeding, advanced service resets, or comprehensive all-module diagnostics.
Extended FAQ
Does the OBDMATE OM901 read ABS and airbag codes?
Yes. Its enhanced diagnostics cover ABS and SRS/airbag modules on supported vehicles, in addition to engine and transmission systems.
Can the OM901 perform bidirectional tests?
No. It reads data and fault codes and can clear supported warnings, but it does not command components or run active actuator tests.
Does it need a subscription?
No recurring subscription is advertised. OBDMATE provides free software updates through its update utility.
Will it work on every OBD2 vehicle?
Generic OBD2 coverage is broad, but ABS, SRS, and transmission support is vehicle-specific. OBDMATE states coverage for most compliant vehicles from 2000 onward, so checking the exact make, model, year, and system is wise.
Can it check battery voltage?
Yes. It can display vehicle battery voltage and includes a DLC-pin voltage test, useful when poor power or connector issues interfere with diagnostics.
Can it reset oil-service lights or program keys?
Those are not core OM901 functions. It should not be purchased for key programming, coding, or a broad menu of maintenance resets.
Final Verdict
The OBDMATE OM901 occupies a useful middle ground. Its four-system coverage, readable 3.5-inch display, live graphing, emissions functions, battery/DLC checks, protective case, and free updates make it meaningfully more capable than a basic code reader. Its ceiling is equally clear: there is no bidirectional control, and enhanced coverage can vary by vehicle. For DIY diagnostics and used-car checks, however, it offers a strong feature set without recurring fees or app dependence.
