When your check-engine light turns on, the immediate question is whether you can trust the code and whether you can reset it without a shop visit. For anyone shopping for automotive diagnostic tools, the choice often comes down to connection type, the systems a scanner can reach, and what the display tells you. In this head-to-head, the $153 TOPDON ArtiDiag 600S and the $164.90 ThinkCar Full System OBD2 are both new code readers that erase codes and update over the internet, but they take different paths to get the job done.
Quick verdict
If you want a scanner that spells out the vehicle systems it can read, the TOPDON ArtiDiag 600S is the more straightforward pick. If you want a tool that works with your phone and feels good in your hand, the ThinkCar Full System OBD2 is the better match. Your decision should hinge on how you prefer to connect and which systems matter for your vehicle.

Where the TOPDON ArtiDiag 600S wins
The ArtiDiag 600S has the longer list of named systems. Beyond engine codes, it includes more module coverage than the ThinkCar's three listed systems. The ArtiDiag 600S is a strong option if you want a code reader that is transparent about what it can handle.
Where the ThinkCar Full System OBD2 wins
The ThinkCar is built for phone-based diagnostics. Its wireless link means it can work as a companion to the device you already own. The ThinkCar also promises full-system coverage, maintenance functions, and re-learn procedures, which gives it an edge when you want to complete a reset after a repair.
Product notes
TOPDON ArtiDiag 600S
Choose the TOPDON ArtiDiag 600S when you want a scanner that names the systems it reads. In addition to the usual engine codes, it can handle ABS, SAS, SRS, TPMS, EPB, and DPF, and it works with OBD, OBDII, CAN, and EOBD interfaces. The kit includes an adapter cable, a USB cable, and a user guide, which is nice for a first-time scan-tool owner. Its WiFi connection gives you a wireless option, and the LCD display plus freeze-frame views help you see what happened before a fault. On the other hand, the ThinkCar brings Bluetooth and phone-based controls to the table, so if you want to read codes from your phone, the ArtiDiag's WiFi path may feel less direct. It's a solid choice for someone who prefers a more traditional handheld layout.
ThinkCar Full System OBD2
Pick the ThinkCar Full System OBD2 when your phone is the center of your diagnostic setup. It connects over Bluetooth to iOS and Android devices, so you can see codes and reset them from a larger screen. The color backlit display, ergonomic grip, and built-in battery make it comfortable for longer sessions, and the check engine light shut-off is exactly what you want when a repair is done. It also promises full-system coverage, maintenance functions, and dealership-level re-learn procedures, which is a strong fit for DIYers who do their own brake or battery work. The trade-off is a shorter named list: it lists ABS, SRS, and ECM, while the ArtiDiag lists six systems. If your main need is clear mobile integration and a handheld scanner that feels good to use, the ThinkCar earns its place.
Final choice by use case
- Choose the TOPDON ArtiDiag 600S if you want the broader named system list, multiple OBD protocols, and an included cable kit.
- Choose the ThinkCar Full System OBD2 if you want a phone-first scanning experience with iOS and Android support and a comfortable handheld design.
