This tool connects to the standard 16-pin OBD2 port found on most petrol and diesel cars sold from around 2010 onwards. Check your vehicle's OBD2 port and confirm it supports the listed OBDII protocols (including CAN/ISO 15765) to ensure compatibility. It is designed for 12V gas and light diesel vehicles. ### What is the difference between a Bluetooth dongle and a handheld code reader? A handheld reader like the Autel MS309 has its own screen and works standalone, while a Bluetooth dongle plugs into the OBD2 port and streams data to a paired smartphone app. Choose the handheld for a self-contained tool, or the dongle if you prefer live data and app-based logging on your phone. ### Can I use this scanner to reset my car's Check Engine Light? Yes, the Autel MS309 scanner allows you to read the fault codes causing the Check Engine Light to illuminate. Once the issue is identified and potentially fixed, you can use the scanner to clear the code and turn off the light. ### Does the Autel MS309 support advanced functions like ABS or transmission diagnostics? No, the Autel MS309 is a basic OBDII code reader. It focuses on engine-related fault codes and emissions monitoring. It does not support advanced functions such as ABS/SRS code reading, transmission diagnostics, or ECU programming. For those needs, Autel offers higher-end models like the MD906 PRO or MK808BT PRO. ### What vehicles are NOT supported by the Autel MS309? Due to security gateway systems, this tool may not access OBDII modules for FCA vehicles (Chrysler, Dodge, Jeep) manufactured after 2017. It also does not support TPMS or other service functions.
