Best Bidirectional OBD2 Scanner with TPMS: 5 Picks Compared

A TPMS warning light after a tire rotation, followed by a component that needs commanding to prove a fault, is the job that calls for a scanner with bidirectional control and TPMS work in the same tool. The answer for best bidirectional obd2 scanner with tpms is to pick a scanner that states both functions in its listing, because several listings in this guide state only part of that pair. The picks below rank those scanners by how completely their listings cover systems, resets, bidirectional control, and TPMS work, with the full-system scanners that state both functions at the top.

Compared on paper

Specs are the manufacturer’s ratings as listed, collected 1 November 2026. None of these listings names an electrical safety listing, so all 5 score zero for safety, while all 5 state a warranty term.

How the points were given

Each scanner is scored out of 10 on performance, build, value, safety and warranty, with the weights published on the How We Pick page.

Shop Scores range from a low of 9.2 to a high of 9.8, with each tool positioned by its weighted points proportionally, and more points always yields a higher score.

What the listings tell you

The listings in this guide number 5 in total. All 5 state a warranty term, 4 state bidirectional control, and 4 state a TPMS function, but only 2 state both functions with full-system diagnostics. The other listings state only 4 systems, or state bidirectional control with no TPMS function stated, or state a TPMS function with no bidirectional control stated. That split is why the ranking below puts the full-system scanners that state both functions first.

Best Bidirectional OBD2 Scanner with TPMS Buying Guide

Bidirectional control

Bidirectional control means the scanner sends commands to vehicle components, rather than only reading codes. The MUCAR sends commands to injectors, fuel pumps, wipers, headlights, door locks, side mirrors and ABS assemblies. The X800BT sends commands to fuel injectors, mirrors, windows and windshield wipers. The XTOOL gives 4K+ bidirectional controls, and the Dollarfix gives 3000+ bidirectional controls. The AD500 listing gives no bidirectional control stated, so it does not meet that part of the keyword on its listing alone.

TPMS work

TPMS work appears in this guide as TPMS relearn and as TPMS reset, and the two terms are not interchangeable in the listings. The MUCAR gives TPMS relearn among its 28+ resets, and it also covers the TPMS module in full-system diagnostics. The X800BT, Dollarfix and AD500 listings give a TPMS reset among their reset services. The XTOOL listing gives no TPMS function stated, so TPMS work is not stated there, even though it gives all-system diagnostics and bidirectional control. For a TPMS job, check the listing for the exact TPMS term it gives, rather than assuming every full-system scanner covers it.

Systems and resets

System coverage decides how much of a vehicle a scanner reaches. The XTOOL gives OE-level all-system diagnostics, the MUCAR and X800BT give full-system diagnostics, and the AD500 and Dollarfix give 4-system diagnostics. Reset counts run from 39+ services on the XTOOL and 34 reset services on the X800BT, through 28+ resets on the MUCAR, down to 10 reset services on the Dollarfix and 6 reset functions on the AD500. A higher reset count does not by itself cover TPMS work, as the XTOOL count shows, so read the reset list with the TPMS term in mind.

Protocols and updates

Protocols decide which late-model vehicles a scanner communicates with. The MUCAR and XTOOL listings give CAN FD and DoIP support, the X800BT gives CAN FD support, and the AD500 gives CAN FD support, while the Dollarfix listing gives no CAN FD or DoIP protocol stated. FCA gateway coverage is stated by the XTOOL, X800BT and AD500 listings, in different forms. Updates also differ: the MUCAR, X800BT, AD500 and Dollarfix listings give lifetime free updates, while the XTOOL gives 3 years of software updates. The X800BT listing also notes that some protocol access may require an additional purchase.

Garage Fit Check

• Screen size: Screens run from 5 inches on the AD500 and Dollarfix to 6 inches on the X800BT and 7 inches on the MUCAR, so check bench and storage space against the screen figure.
• Power figures: Battery figures stated are 5000mAh on the MUCAR, 3350mAh on the AD500, and 3150mAh on the Dollarfix, while the X800BT and XTOOL listings give no battery capacity figure.
• Wireless range: The X800BT gives a Bluetooth 5.0 VCI with a 33 ft wireless range, for cable-free diagnostics away from the vehicle port.
• Coverage check: Before the first job, check vehicle coverage and the exact TPMS and bidirectional terms for the vehicle, since function menus vary by vehicle in the listings.

FAQ: garage tools

Which scanners in this guide give both bidirectional control and TPMS?

The X800BT, MUCAR and Dollarfix listings give both bidirectional control and a TPMS function. The XTOOL gives bidirectional control with no TPMS function stated, and the AD500 gives a TPMS function with no bidirectional control stated.

What is the difference between full-system and 4-system diagnostics here?

Full-system and all-system scanners in this guide cover Engine, Transmission, ABS, TPMS and other modules, while 4-system scanners cover Engine, Transmission, ABS and SRS. The AD500 and Dollarfix listings give those 4 systems, while the MUCAR, X800BT and XTOOL listings give full-system or all-system coverage.

How many reset services does each scanner give?

The XTOOL gives 39+ services, the X800BT gives 34 reset services, the MUCAR gives 28+ resets, the Dollarfix gives 10 reset services, and the AD500 gives 6 reset functions. Those counts come from each listing, and the reset lists differ by vehicle.

Do these scanners need a subscription for updates?

The MUCAR, X800BT, AD500 and Dollarfix listings give lifetime free updates, while the XTOOL gives 3 years of software updates. The X800BT listing also notes that some protocol access may require an additional purchase, separate from its lifetime free updates.

Which scanner gives ECU coding?

The XTOOL gives ECU coding and PMI functions, with FCA AutoAuth and CAN FD and DoIP support. No other listing in this guide states ECU coding, so that function belongs to the XTOOL listing alone in this guide.
