Handheld OBD2 Scanners That Actually Read ABS and SRS Codes
For most home mechanics, the Autel MaxiCOM MK808 covers the widest range of systems with real bidirectional control. The BlueDriver Bluetooth Pro pairs to a phone for easier repair reports, and the FOXWELL NT301 handles routine check engine light diagnosis at a lower cost without ABS or SRS coverage.
The Autel MaxiCOM MK808 suits owners who want one tool for engine, ABS, SRS and transmission codes plus real bidirectional actuation tests. It costs more than a basic reader, so drivers who only chase an occasional check engine light are better served by something simpler like the FOXWELL NT301.
OBD2 scanners vary enormously in system coverage, from generic engine codes to full bidirectional control. We compared published system coverage, service reset functions, connection type and owner feedback on reliability before ranking these seven.
How to choose
What to look for in an OBD2 scanner Start by checking system coverage rather than assuming every scanner reads the same codes. A generic reader only pulls engine codes, while a multi system tool adds ABS, SRS and transmission. Decide next whether a built in screen or a phone app fits how you already work in the garage, since both approaches read the same underlying data.
Reading ABS, SRS and other systems Plenty of budget scanners only clear the check engine light and stay blind to a flashing ABS or airbag warning. A multi system tool like the LAUNCH CRP123X or the INNOVA 3160g pulls codes from those modules separately. This matters most for anyone chasing a dash warning beyond the standard engine light.
Bidirectional control and service resets A read only scanner tells you what failed, but a bidirectional tool can also trigger a component to test it directly, such as cycling an EPB motor or relearning a steering angle sensor. Oil resets and similar service functions save a trip to the dealer after routine maintenance. Occasional DIY users may never need this layer, while frequent home mechanics benefit from it often.
Choosing between a handheld tool and a Bluetooth adapter A built in screen works without pulling out a phone, which matters in a cold garage or with gloves on. A compact adapter like the OBDLink MX+ trades that convenience for the ability to stay plugged in and log data continuously. Pick based on whether you want a one time diagnostic check or ongoing monitoring between drives.
The shortlist, ranked
Autel MaxiCOM MK808
Autel’s MK808 reads and actuates across engine, transmission, ABS, SRS and several other systems on one handheld unit. Bidirectional control supports actuation tests like EPB activation and TPMS relearn rather than just pulling codes. A built in 7 inch touchscreen means no phone pairing is required in the shop.
Pros
- Reads and actuates across most vehicle systems
- Built in screen needs no phone pairing
- Covers oil reset, EPB and SAS service functions
Cons
- Larger and pricier than a basic code reader
- Occasional vehicle specific bidirectional gaps
BlueDriver Bluetooth Pro OBDII Scan Tool
BlueDriver connects over Bluetooth to a free iOS or Android app rather than relying on a built in screen. Beyond generic codes, it reads OEM specific data on ABS and SRS systems. Repair reports pull from a shared database of fixes other owners found for the same code.
Pros
- App interface easier to read than many handheld menus
- Repair reports point to a likely fix, not just a code
- Pocket sized housing
Cons
- No built in screen for a quick check
- No bidirectional actuation tests
FOXWELL NT301
FOXWELL keeps the NT301 focused on generic engine codes rather than trying to cover every system. A small color screen shows codes and basic live data without needing a paired phone. Owners who only need to identify a check engine light cause rarely need more than this.
Pros
- Straightforward for check engine light diagnosis
- Built in screen works without a phone
- Simple menu for infrequent use
Cons
- No ABS, SRS or transmission coverage
- No bidirectional control functions
LAUNCH CRP123X
LAUNCH built the CRP123X around the four systems most owners ask about: engine, transmission, ABS and SRS. Beyond code reading, the service menu handles oil resets, electronic parking brake service and throttle relearns. Lifetime software updates come with the unit at no extra subscription.
Pros
- Covers the four systems most owners ask about
- Service reset menu beyond basic code reading
- Lifetime updates with no subscription
Cons
- Bidirectional tests more limited than a professional tool
- Menu depth takes a session to learn
INNOVA 3160g
INNOVA pairs the 3160g with the optional RepairSolutions2 app, which translates a raw code into a plain language explanation of what likely failed. ABS and SRS reading come standard alongside engine codes. The unit also works entirely on its own screen for anyone who prefers skipping the app.
Pros
- Explains codes in plain language for new users
- Works standalone or paired to the app
- Covers ABS and SRS at an entry price
Cons
- No bidirectional actuation tests
- Transmission coverage thinner than a professional tool
ANCEL FX2000
ANCEL brings bidirectional actuation tests down to a lower price point than Autel’s higher end tools. Full system scanning covers engine, transmission, ABS, SRS and more on supported vehicles. A built in color touchscreen means it works without pairing to a phone first.
Pros
- Bidirectional tests at a lower cost than Autel
- Wide system coverage for the price
- Built in screen, no phone required
Cons
- Bidirectional coverage thinner on some older vehicles
- Software menus less polished than premium brands
OBDLink MX+
OBDLink’s MX+ skips a screen entirely and pairs over Bluetooth to a phone app, which suits owners who want to leave it plugged in continuously. It supports several third party diagnostic apps beyond OBDLink’s own, and logs trip data over time rather than just one time checks. Enhanced coverage on some manufacturer specific codes goes beyond the generic standard.
Pros
- Small enough to leave plugged in permanently
- Works with several third party diagnostic apps
- Good for ongoing data logging, not just one time checks
Cons
- No built in screen for a quick look
- Full ABS and SRS depth varies by vehicle and app

Frequently asked questions
Do OBD2 scanners have a built in display screen?
Many handheld models like the Autel MaxiCOM MK808 and LAUNCH CRP123X include a built in screen. Compact Bluetooth adapters such as the OBDLink MX+ skip the screen and rely on a paired phone app instead.
What is the difference between a code reader and a bidirectional scanner?
A code reader only pulls stored fault codes, while a bidirectional scanner can also send commands to actuate a component, such as cycling a parking brake motor during service.
Can an OBD2 scanner read ABS and SRS codes?
Only multi system scanners read ABS and SRS modules. A generic code reader like the FOXWELL NT301 is limited to engine codes and will not show those faults.
What is a bidirectional OBD2 scanner used for?
Bidirectional tools run active tests on a system, such as triggering an EPB motor, relearning a steering angle sensor, or cycling a TPMS sensor during a tire rotation.
Are professional grade scanners worth it for home use?
They cost more but cover more systems and service functions than a basic reader. Owners who do their own brake, suspension or sensor work tend to use that extra coverage regularly.
How do I reset the oil service light with an OBD2 scanner?
A scanner with a service function menu, such as the LAUNCH CRP123X or ANCEL FX2000, includes an oil reset option that clears the maintenance reminder after an oil change.
Will an OBD2 scanner work on any car?
Generic OBD2 codes work on nearly all vehicles sold after the mid 1990s. Enhanced and bidirectional functions vary more by manufacturer, so check the scanner’s vehicle coverage list first.
Do I need a subscription to keep using an OBD2 scanner?
Most consumer scanners, including the LAUNCH CRP123X, offer free lifetime updates. Some professional tools charge for ongoing software subscriptions, so check the listing before buying.
What does freeze frame data mean on a scan tool?
Freeze frame data captures the sensor readings at the exact moment a fault code triggered, which helps pinpoint what was happening in the engine when the problem occurred.
The bottom line
The Autel MaxiCOM MK808 is the right pick for anyone who wants one tool that covers engine, ABS, SRS and transmission codes with real bidirectional control. Drivers who only need to check an occasional engine light should save money with the FOXWELL NT301 instead. Owners focused specifically on ABS, SRS and service resets without the full Autel price tag get strong coverage from the LAUNCH CRP123X.
