# Best wireless Bluetooth scan tools with a tablet Source: https://codeandclear.com/best/best-wireless-bluetooth-scan-tool Publisher: Code & Clear. Picks are chosen from what each Amazon listing states, not from hands-on tests. Method: https://codeandclear.com/how-we-pick A wired scanner ties you to the OBD2 port under the dash. That is fine for reading codes, but active tests and relearns often mean watching a part in the engine bay or under the car while the tool commands it. A wireless scan tool splits the job in two: a small VCI dongle stays plugged into the port and talks to a tablet you carry around. The things that separate these tools are the link itself (Bluetooth or WiFi, and the stated range), how many active tests and service functions the listing claims, support for CAN FD, DoIP and FCA AutoAuth on newer vehicles, and what the listing says about updates. This guide compares seven VCI and tablet kits plus one phone-based option, using only the facts in each Amazon listing. ## Picks ### 1.
