Sturdy and Compact: Equipped with a 2.5 foot cable made of very thick, flexible insulation. It is important to have a sturdy scanner as it can easily fall to the ground when working in a car.

Thanks to its compact design and light weight, transporting the device is not a problem. The buttons are clearly labelled and the screen is large and displays results clearly.
OBDII Protocols and Car Compatibility: Many cheap scan tools do not really support all OBD2 protocols. This is not the case with the AD310 scanner as it can support all OBDII protocols such as KWP2000, J1850 VPW, ISO9141, J1850 PWM and CAN. This device also has extensive vehicle compatibility with 1996 US-based, 2000 EU-based and Asian cars, light trucks, SUVs, as well as newer OBD2 and CAN vehicles both domestic and foreign.

CEL Doctor: The ANCEL AD310 is one of the best-selling OBD II scanners on the market and is recommended by Scotty Kilmer, a YouTuber and auto mechanic. It can easily determine the cause of the check engine light coming on, quickly read and clear diagnostic trouble codes, read live data & hard memory data, view freeze frame, I/M monitor readiness and collect vehicle information. Instead of taking car to mechanic shop, you can use it to check the trouble code and show code definition by yourself.
Accurate Fast and Easy to Use: The AD310 scanner can help you or your mechanic understand if your car is in good condition, provides exceptionally accurate and fast results, reads and clears engine trouble codes in seconds. If you want to find out the cause of the check engine light, this device will let you know immediately and fix the problem right away without any car knowledge.
