Best Obd2 Scanner To Erase Codes for Engine and System Faults

#1 · Best Overall

1. BLCKTEC 460T

• Dimensions: 7.75"L x 1.5"W x 4.4"H
• Screen Size: 4.3 in
• Dimensions: 7.75"L x 1.5"W x 4.4"H

Best for: Multi-system reset and diagnostics.

Why it ranks #1: Reads and clears engine, transmission, ABS, and SRS codes, and adds all 10 OBD2 modes, live data, and 12 reset services.

The BLCKTEC 460T lists diagnostics for engine, transmission, ABS, and SRS alongside 12 reset services, giving owners a broader tool for troubleshooting and maintenance. Its 4.3-inch screen displays real-time live data, while the included storage case helps keep the scanner and accessories together between jobs.

All-system diagnostics and support for all 10 OBD2 modes let users investigate more than engine codes, with live data available for checking vehicle information. The listed reset services include oil, TPMS, EPB, BMS, SAS, DPF, and throttle resets, plus ABS bleeding and battery testing. Auto VIN adds a vehicle-identification step to the workflow. Function availability depends on the vehicle, so the extensive menu does not mean every service applies to every car.

Skip it if you only need basic engine-code reading; the ANCEL AD310 focuses on reading and clearing engine codes.

The 460T fits home mechanics and professionals who want multi-system diagnostics and maintenance resets in one handheld tool. Its broad functions are useful only where supported by the vehicle, so check that boundary before relying on a particular service.

#2 · Four-System Coverage

2. OBDMATE OM901

• Screen Size: 3.5 in

Best for: Four-system handheld diagnostics.

Why it ranks #2: Clears fault codes across ABS, SRS, engine, and transmission; its 3.5-inch screen and plug-and-play setup suit direct handheld use.

The OBDMATE OM901 reads and clears faults across ABS, SRS, engine, and transmission systems, extending code-clearing beyond check-engine diagnostics. Its 3.5-inch TFT screen presents sensor readings, and plug-and-play operation avoids Bluetooth pairing, Wi-Fi connection, or pre-installation.

Four-system diagnostics let owners select among ABS, SRS, ECM, and transmission rather than relying on an engine-only reader. The scanner also provides data streams and Auto VIN; for transmission live data, the listed path leads through vehicle scan and TCM system selection. A 3.5-inch screen supports viewing those readings, while the included hard carrying case and USB Type-C cable help with storage and connection. The listed systems define its coverage, not every vehicle function.

Skip it if you want 12 reset services such as oil, TPMS, and ABS bleeding; the BLCKTEC 460T lists those services.

The OM901 suits owners who want handheld code clearing and data readings across four major systems without wireless setup. It is a practical fit for that coverage, but buyers needing a wider set of reset services should consider the narrower scope.

The AL319 is for check-engine diagnostics; its information explicitly excludes reset functions such as airbag and SRS resets.

Skip it if you need ABS, SRS, or transmission system coverage; the BLCKTEC 460T lists diagnostics for those systems.

Pick the AL319 for check-engine investigations where code lookup, freeze frame, and I/M readiness matter. Its seven-language support is useful for multilingual users, but it is not the choice for airbag or SRS resets.

• Screen Size: 2.4 in
• Dimensions: 8.9"L x 6.9"W x 1.4"H

That distinction helps keep expectations clear for drivers who mainly want to read and clear engine codes. Its 2.4-inch screen offers a dedicated display, while the supplied scanner and manual keep the kit straightforward. Supported data streams depend on the vehicle’s OBDII system, so the tool’s available information can vary by vehicle.
