# Best Autel scanners: which MaxiDiag, MaxiCOM, MaxiCheck or MaxiSys to buy Source: https://codeandclear.com/best/best-autel-scanner Publisher: Code & Clear. Picks are chosen from what each Amazon listing states, not from hands-on tests. Method: https://codeandclear.com/how-we-pick Autel sells dozens of scanners, and the listings often say one model works the same as three others. The line names help. MaxiDiag (MD806, MD808, MD906) are all-system code readers with service resets but no listed active tests. MaxiCOM and MaxiCheck (MK808S, MX900, MK900BT) add bidirectional control and more services on an Android tablet, and the BT models use a wireless VCI. MaxiTPMS tools like the TS900 add tire sensor programming. MaxiSys (MS906 PRO, Elite II Pro) adds ECU coding and, on the top models, J2534 programming. This guide picks one or two models from each line and compares them by systems, active tests, service functions and connection, using only what each Amazon listing states, so you can match the line to the work you do. ## Picks ### 1.
