This car diagnostic tool supports Reading DTCs, displaying DTC definition under the codes, Freeze Frame & I/M Readiness etc to figure out the root cause of the Check Engine Light (CEL) and turning it off, to help you detect any potential problems, and to avoid excessive costs for unnecessary repairs.
By offering a live data stream this OBDII scanner will give users ongoing data while the engine is on. Allows you to diagnose issues as they occur and offers users a clear path to the root cause, while also showing you that the code involves issues with a specific system in the vehicle such as the brakes or airbags.
The MS309 mini pocket OBD2 scanner supports all major OBD2 protocols, including KWP2000, ISO2000, ISO9141, J1850 VPW, J1850 PWM, and CAN. It works with 99% of OBD2-compliant vehicles—passenger cars and light trucks alike. If your vehicle has a standard 16-pin OBD2 port and was manufactured within typical compliance years, it’s likely supported. (Most U.S. vehicles after 1996, EU after 2002, and Asia after 2008). Note: Not compatible with electric vehicles (EVs), hybrid vehicles, or models that do not support OBD2 protocols.
