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.
ADAS calibration routines only run once a tablet is paired with the correct hardware — frames, targets, or compatible VCIs. Confirm compatibility before you buy.
Six Scan Tools Worth Stocking
Autel MaxiSYS Ultra S2
Best Overall$6,499
Autel's current flagship, built for shops that do a bit of everything. A 13.7-inch anti-glare touchscreen, 12GB RAM, 512GB storage, and the MaxiFLASH VCMI2 — a 6-in-1 interface bundling a VCI, 4-channel oscilloscope, waveform generator, multimeter, and CAN bus testing. Full US, Asian, and European coverage from 1996 on, OE-level coding, bidirectional tests, and Topology 3.0 network mapping.
Add the IA900 or IA1000 software package and it gains 4-wheel alignment plus static and dynamic ADAS calibration. A big commitment, but for a full-service shop it replaces several tools at once.
Shop the Autel MaxiSYS Ultra S2 →Autel MaxiSYS MS919 S2
Advanced Diagnostics$5,199
Autel's measurement-focused tablet and successor to the MS919. The MaxiFLASH VCMI2 pairs a 4-channel oscilloscope and waveform testing with full OE-level diagnostics, so techs chase intermittent electrical faults on a scope instead of guessing. Topology 3.0 maps the vehicle's networks; split-screen live data and enhanced PID analysis speed up driveability work. 11-inch wireless tablet, US/Asian/European coverage from 1996 on.
Sits just under the Ultra — same diagnostic and measurement depth, minus wheel alignment software and IA900 frame support.
Shop the Autel MaxiSYS MS919 S2 →Autel MaxiSYS MS906 Max ADAS
Best Value Adding ADAS$2,590
A 10.1-inch wireless tablet aimed at shops ready to grow into calibration work. Runs full-system diagnostics and bidirectional tests across a wide vehicle range, and launches ADAS calibration routines once paired with Autel ADAS hardware — a strong daily-driver scan tool now, with a path into calibration revenue later.
Priced for independents and mobile techs who want room to expand without jumping straight to a flagship.
Shop the Autel MaxiSYS MS906 Max ADAS →Autel MaxiSYS MS906 Pro2-TS
Diagnostics Plus TPMS$1,995 $2,795
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.
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.
Shop the Autel MaxiSYS MS906 Pro2-TS →Launch Tech CRP 919 Max
Best Under $1,000$899.95
Shows how far a sub-$1,000 tool has come. 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.
A strong pick 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 — for shops that don't need built-in ADAS calibration.
Shop the Launch Tech CRP 919 Max →Topdon ArtiDiag600S
Best Entry-LevelPriced for everyday code work
The tool to reach for when you want dependable code work without the extras. Covers more than 90 US, European, and Asian makes, reads the four main systems (engine, transmission, airbag, ABS), and runs eight maintenance functions — oil, brake, SAS, BMS, DPF, and TPMS resets plus ABS bleeding. CAN-FD support keeps it current, and lifetime updates keep it useful for years.
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.
Shop the Topdon ArtiDiag600S →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.
