Your scan tool is one of the hardest-working pieces of equipment in the bay. It reads and clears trouble codes, streams live sensor data, runs bidirectional tests, and handles the pre- and post-scans you can bill for on nearly every repair order. A capable automotive scan tool pays for itself fast. A weak one slows your techs down and pushes work you could have kept out the door.
Below are six scan tools worth a look for shops, ranging from a flagship do-everything tablet to a budget auto diagnostic tool for core code work. Every model here is stocked at ADAS Depot, and we've flagged the type of shop each one fits best.
What a Scan Tool Does for Your Shop
A car diagnostic scanner talks directly to a vehicle's electronic control units. That connection lets a technician pull diagnostic trouble codes, watch live and freeze-frame data, and confirm that a repair worked before the car leaves the lot. On newer vehicles, the same tool launches calibration routines for systems like lane departure warning and automatic emergency braking.
For most shops, scan tools also drive revenue. Pre- and post-repair scans are billable on the majority of collision jobs, and the diagnostic reports these tools generate back up your work with insurers. That mix of billable scanning, faster troubleshooting, and fewer comebacks is why a scan tool tends to post one of the highest returns of any tool on the bench.
How to Choose the Best Scan Tool for Cars
The best scan tool for cars in your shop depends on the work you take in. A few things to weigh before you buy:
- Vehicle coverage: Look at how many domestic, Asian, and European makes a tool supports, and how far back its model-year range goes.
- Bidirectional control: A professional car diagnostic tool should command components, not just read codes, so techs can run active tests.
- ADAS capability: If you calibrate cameras and radar, pick a tablet that can launch those routines when paired with the right hardware.
- Updates: Coverage grows through software subscriptions. Check what's included and what renews annually.
- Screen, speed, and budget: A faster processor and larger display save time on high-volume days, while a leaner auto diagnostic tool may be all a smaller shop needs.
Autel MaxiSYS Ultra S2: Best Overall Automotive Scan Tool
The Autel MaxiSYS Ultra S2 is Autel's current flagship, and it's built for shops that do a bit of everything. It pairs a 13.7-inch anti-glare touchscreen with 12GB of RAM, 512GB of storage, and the MaxiFLASH VCMI2, a 6-in-1 interface that bundles a VCI, 4-channel oscilloscope, waveform generator, multimeter, and CAN bus testing into one device. Full US, Asian, and European coverage from 1996 on, OE-level coding, bidirectional tests, and Topology 3.0 network mapping (with the ability to ping individual modules) make it a fast way to get from code to fix. AI touches like the "Hey Max" voice assistant and camera-based digital inspection round it out.
It's also the tablet to build a calibration bay around. Add the IA900 or IA1000 software package and the Ultra S2 gains 4-wheel alignment plus static and dynamic ADAS calibration, pairing with Autel's automated frames. The base tablet runs $6,499. It's a big commitment, but for a full-service shop it replaces several tools at once and leaves room to grow into alignment and ADAS work.

Autel MaxiSYS MS919 S2: Best for Advanced Diagnostics and Waveform Testing
The MaxiSYS MS919 S2 is Autel's measurement-focused tablet and the current successor to the MS919. Its MaxiFLASH VCMI2 pairs a 4-channel oscilloscope and waveform testing with full OE-level diagnostics, so techs can chase intermittent electrical faults on a scope instead of guessing. Topology 3.0 maps the vehicle's networks and lets you ping and monitor individual modules, while split-screen live data and enhanced PID analysis speed up driveability work. The 11-inch wireless tablet covers US, Asian, and European vehicles from 1996 on.
At $5,199, it sits just under the Ultra. The trade is simple: you get the same diagnostic and measurement depth, minus the Ultra's wheel alignment software and IA900 frame support. For a shop that lives in electrical and driveability diagnosis and calibrates through other hardware, that's money well saved.

Autel MaxiSYS MS906 Max ADAS: Best Value for Shops Adding ADAS
The MaxiSYS MS906 Max ADAS is a 10.1-inch wireless tablet aimed at shops ready to grow into calibration work. It runs full-system diagnostics and bidirectional tests across a wide vehicle range, and it can launch ADAS calibration routines once paired with Autel ADAS hardware. That makes it a smart on-ramp: you get a strong daily-driver scan tool now, with a path into calibration revenue later.
At $2,590, it's priced for independents and mobile techs who want room to expand without jumping straight to a flagship.

Autel MaxiSYS MS906 Pro2-TS: Best for Diagnostics Plus TPMS
The MaxiSYS MS906 Pro2-TS packs professional full-system diagnostics into an 8-inch wireless tablet and folds in full TPMS service. For shops that turn a lot of tires alongside general repair, having sensor programming and relearns in the same tool as your diagnostics cuts down on device juggling.
Currently $1,995 (down from $2,795), it's one of the better-priced ways to put a capable auto diagnostic tool and a TPMS tool in a tech's hands at the same time.

Launch Tech CRP 919 Max: Best Professional Car Diagnostic Tool Under $1,000
The Launch Tech CRP 919 Max shows how far a sub-$1,000 tool has come. It's a professional-grade car diagnostic scanner built to handle complex repairs, with the full-system coverage and active-test functions a working tech leans on day to day. For a second-bay tool, a mobile setup, or a shop that wants a capable professional car diagnostic tool without a four-figure price tag, it earns its place.
At $899.95, it's the value pick in this lineup for shops that don't need built-in ADAS calibration.

Topdon ArtiDiag600S: Best Entry-Level Scan Tool
The Topdon ArtiDiag600S is the tool to reach for when you want dependable code work without the extras. It covers more than 90 US, European, and Asian makes, reads the four main systems (engine, transmission, airbag, and ABS), and runs eight maintenance functions, including oil, brake, SAS, BMS, DPF, and TPMS resets plus ABS bleeding. CAN-FD support keeps it current with newer models, and lifetime updates keep it useful for years.
It won't calibrate ADAS or run advanced measurements, but as a low-cost auto diagnostic tool for everyday scanning and service resets, it's hard to beat.
Match the Scan Tool to the Work You Do
The best automotive scan tool comes down to the mix of work you take in. Full-service and calibration shops get the most from the MaxiSYS Ultra S2. Driveability-focused shops lean on the MS919 S2. Independents growing into ADAS do well with the MS906 Max ADAS, while tire-heavy shops like the MS906 Pro2-TS. If budget leads the decision, the Launch CRP 919 Max and Topdon ArtiDiag600S put strong scan tools in reach for less.
