Autel MaxiCheck MX900-TS

Buy the Autel MaxiCheck MX900-TS if you need full TPMS sensor work and bidirectional control in one tool and you’re already running into newer CAN-FD and DoIP vehicles. Skip it if your work doesn’t touch either of those yet, a smaller Autel model covers the same core diagnostics for less.

The short version: Amazon’s listing and Autel’s own documentation line up well on the core capabilities. Full TPMS programming, bidirectional active tests, and CAN-FD/DoIP support are all independently confirmed. The one thing to know before you buy isn’t a capability at all, it’s that this exact scanner is sold for U.S. use only, more on that below.

What the MX900-TS Actually Does

Autel’s own listing confirms an 8-inch, 1280×800 touchscreen running Android 11 with 4GB RAM and 64GB storage, a 7700mAh battery, and wireless vehicle connection through the included MaxiVCI V150 module. Autel’s technical documentation separately confirms CAN-FD and DoIP support, the newer communication standards a growing number of recent vehicles use.

TPMS is where this scanner is strongest: full diagnostics, sensor activation and relearn for the large majority of known sensors, and MX-Sensor programming, not just a reset. Autel’s own page confirms 40+ named service functions directly. Amazon’s listing separately advertises 3,000+ active tests as its own figure, we didn’t find that specific number anywhere on Autel’s own pages, though nothing there contradicts it either. Treat the two counts as independent claims from two different sources, not one broken down into the other.

What Amazon Says vs. What Autel Confirms

Amazon’s listing for this exact MX900-TS advertises it as a “TPMS & Bidirectional Scanner” with “Top Sensor Programming,” 3,000+ active tests, and 40+ service functions, and describes it as an update of several other Autel models in the same family. [Amazon]

Autel’s own product page independently confirms TPMS, bidirectional control, and the 40+ service function count. [Autel] Autel’s technical documentation goes further than Amazon’s listing in one place: CAN-FD and DoIP support is confirmed there directly, something Amazon’s own listing never mentions, an omission in Amazon’s favor, not a conflict. [Autel technical]

Amazon’s listing also states a specific number, 3,000+ active tests. We checked Autel’s product page and technical page and didn’t find that figure confirmed anywhere. That’s an Amazon claim we couldn’t independently verify, not something Autel denies, Autel’s own pages simply don’t state a number. [Amazon] [Autel] [Autel technical]

The one place the two sources don’t line up: Amazon’s listing describes this scanner as related to several other Autel models by name. Neither Autel’s product page nor its technical documentation confirms that equivalence, so treat that specific claim as unverified rather than assume it. [Amazon] [Autel] [Autel technical]

What this means for you: the capabilities that actually drive the buying decision, TPMS, bidirectional control, and newer-protocol support, are independently confirmed by both sources, safe to rely on. The 3,000+ active-test figure and the sibling-model claim are Amazon-only; they don’t change what the scanner can do, but don’t treat them as manufacturer-verified either.

Injector Coding Is Not the Same as ECU Coding

Autel documents Injector Coding among the MX900-TS’s 40+ service functions, letting a shop rewrite injector-specific codes after a fuel injector replacement. That’s real and confirmed, but it’s narrower than general ECU Coding. Neither Autel’s retail page nor its technical documentation uses the broader “ECU Coding” phrase for this model. If unlocking hidden features or coding across many vehicle systems is your main reason to buy, the Autel MaxiSys MS906 Pro is the model Autel documents that capability for directly, see the alternative note below for what you’d trade away to get it.

Who This Scanner Actually Fits

The MX900-TS fits a shop or mobile mechanic who regularly handles TPMS sensor work, wants bidirectional active tests in the same tool, and is seeing enough 2020-and-newer vehicles that CAN-FD/DoIP support matters. It’s more tool than you need if basic code reading is your main job, and it’s the wrong pick if broad ECU-level coding, not TPMS and service resets, is what you’re actually after.

Important Limitations

Autel’s own listing states this exact scanner is subject to IP restrictions and can only be used and shipped within the United States. If you’re buying from outside the U.S. or need a scanner for a vehicle registered elsewhere, that rules this one out regardless of how well the capabilities otherwise match what you need.

Autel includes one year of free software updates. Continued updates after that run through Autel’s paid renewal program (the Total Care Program), confirmed to exist by multiple independent Autel-authorized sellers, but we didn’t find a current, official Autel-listed renewal price to quote here, confirm the cost directly with Autel or an authorized seller before you factor it into a long-term budget.

Choose It, Skip It, or Consider Something Else

Choose the MX900-TS if you need full TPMS sensor programming and bidirectional control in one tool, your vehicle mix includes newer CAN-FD/DoIP models, and you’re buying and using it inside the United States.

Skip it if your vehicles don’t touch CAN-FD yet or TPMS sensor work isn’t a regular part of your job, a smaller Autel model covers the core bidirectional diagnostics for less.

Consider the Autel MaxiCheck MX808S-TS instead if you want the same TPMS-plus-bidirectional combination on a smaller 7-inch screen. Autel’s page for that model confirms the same bidirectional testing but doesn’t mention CAN-FD or DoIP one way or the other, so if newer-protocol support is a must-have, the MX900-TS is the confirmed choice.

Consider the Autel MaxiSys MS906 Pro instead if broad ECU Coding and hidden-feature access matter more to you than TPMS work. Worth knowing before you switch: Autel’s own spec table for the MS906 Pro lists TPMS as not included, even though a separate marketing line on the same page mentions it, so don’t buy the MS906 Pro expecting TPMS support.

Our Verdict

The MX900-TS earns its price if TPMS sensor programming and bidirectional control together, on vehicles new enough to need CAN-FD/DoIP, is actually what you need. Amazon and Autel agree on those core points more closely than on most scanners we’ve checked. The two things worth double-checking yourself before buying are simple: you’re using it inside the United States, and you don’t actually need broader ECU Coding than Injector Coding provides.

Frequently Asked Questions

Can I use the MX900-TS outside the United States?

No. Autel’s own listing restricts this scanner to use and shipping within the United States.

Is the MX900-TS compatible with my specific vehicle?

Our data confirms it against a range of makes and generations in SCG’s database, but exact coverage depends on your specific year, make, and model. Use the Finder to check your vehicle directly rather than assuming coverage from the general compatibility range.

What happens after the first year of free updates?

Autel moves you to a paid renewal program. We couldn’t find a current, official price for it on Autel’s own site, confirm the cost with Autel or an authorized seller before you rely on long-term free updates.
