Compared on paper

These numbers are the tool makers’ rated figures, as their listings print them on 28 October 2026. Function availability depends on the vehicle, as both full-data listings state, so check the year, make and model before buying.

How the points were given

The Shop Score weighs performance (system coverage and reset services), build, value, safety and warranty. A factor the listing does not state scores zero, which is why the two title-only picks score zero on warranty and every pick here scores zero on safety: no safety certification is stated for any of them.

We map each tool’s weighted total onto a 9.2 minimum and 9.8 maximum in a straight line, so the point order and score order match.

What the listings tell you

Two listings here give full bullets and feature details, while the other two give a title only. Only the KINGBOLEN states a warranty term, and only it states a size and weight. The BLCKTEC is the only pick with a stated free update and Auto VIN. No listing here states a safety certification, so safety scores zero across the guide.

Buying guide: the best obd2 scanner for chevy traverse

GM coverage vs all-brand modes

The KINGBOLEN splits its coverage in two: full 10 OBD2 modes for all brands after 1996, and advanced features such as reset services and active commands only for GM vehicles like Buick, Chevy, Cadillac and GMC. The BLCKTEC states all-system diagnostics and all 10 OBD2 modes with no brand limit named. The title-only picks name no brand coverage at all. One limit matters for newer GM vehicles: the KINGBOLEN does not currently support 2011+ GM vehicles that require CANFD protocol.

Reset services

Reset services separate a code reader from a workshop tool. The KINGBOLEN names all reset functions, including TPMS reset, ABS bleeding, oil reset, injector coding, SAS reset, BMS reset, gearbox reset, AFS reset, sunroof, brake reset, suspension reset and engine power balance monitoring. The BLCKTEC names 12+ services, including oil maintenance reset, ABS bleeding, EPB reset, SAS recalibration, DPF reset, throttle body relearn, battery reset, TPMS relearn, transmission reset, fluid change reset and maintenance reset. Neither title-only pick names a reset service.

Phone apps and updates

The KINGBOLEN works through a phone: Bluetooth to iOS or Android with the EDIAG app, and it needs WiFi to operate. It does not work with tablets. Updates are lifetime with no subscription fee. The BLCKTEC title states a free update, and no app or connection is named. The title-only picks state no update or app terms. When the tool depends on a phone, check the app and the connection before the first job.

Battery checking

Battery work appears in three forms here. The BLCKTEC names a battery check and a battery reset among its services. The ANCEL title names a 12V battery analyzer with cranking and charging system checks. The KINGBOLEN names a BMS reset, which is a battery management service, not a battery check. The FOXWELL title names no battery feature. Match the battery claim to the job: a check for a weak battery, a reset after a battery swap.

What live data and freeze frame show

Live data shows what the vehicle reports while it runs, and freeze frame captures the readings from the moment a code set. The KINGBOLEN reads real-time data and freeze frame across its full-system coverage. The BLCKTEC offers real-time OBD2 and OEM live data with freeze frame data. The title-only picks name live data in their titles but state no freeze frame. Live data helps when a code comes and goes; freeze frame helps when the fault only shows under load, or when the light goes out before the vehicle reaches a reader.

Garage Fit Check

• Check the phone app first: the KINGBOLEN needs the EDIAG app on iOS or Android and WiFi to operate, and it does not work with tablets.
• Check CANFD before buying for a newer GM: the KINGBOLEN does not currently support 2011+ GM vehicles that require CANFD protocol.
• Check function coverage for the year, make and model: both full-data listings state that function availability depends on the vehicle.
• Check the warranty term: 1 year on the KINGBOLEN, none stated on the other three picks.

FAQ: garage tools

Will an OBD2 scanner work on a Chevy Traverse?

The KINGBOLEN supports full 10 OBD2 modes for all brands after 1996, and its advanced features cover GM vehicles including Chevy. Function availability varies by model and year, so confirm coverage for the Traverse year before buying.

What does a bidirectional scan tool do?

A bidirectional tool sends commands from the scanner to the vehicle computer to drive actuators and run active commands. The KINGBOLEN names turning on the radiator fan, modulating the throttle and opening or closing windows as examples, which helps find a bad component without removing parts.

Do I need a subscription for updates?

The KINGBOLEN states lifetime updates with no subscription fee. The BLCKTEC title states a free update. No update term is stated for the title-only picks.

Can a scanner check a battery?

The BLCKTEC names a battery check and a battery reset. The ANCEL title names a 12V battery analyzer with cranking and charging system checks. The KINGBOLEN names a BMS reset, which is a battery management service rather than a battery check.

What is an active command?

An active command sends a signal from the scanner to the vehicle computer to drive an actuator, such as turning on the radiator fan or modulating the throttle. The KINGBOLEN lists active commands among its bidirectional features, and they help find a bad component by watching how the part responds.
