The Autel MaxiScan MS509 OBD2/EOBD scanner is a powerful yet user-friendly handheld tool designed to help both professional technicians and DIY enthusiasts diagnose car problems quickly and accurately. Compatible with all OBDII and EOBD compliant vehicles, this scanner supports all nine OBDII test modes, making it an invaluable asset for anyone looking to understand and resolve their vehicle’s issues.
This easy-to-use scanning tool provides fast access to engine-based EOBD fault codes. Equipped with CAN capability, the MaxiScan MS509 delivers clear and concise DTC definitions on its large, backlit LCD screen. It retrieves generic codes (P0, P2, P3, and U0) related to engine emissions, as well as manufacturer-specific codes (P1, P3, and U1). Beyond reading codes, the Autel MS509 can turn off the Check Engine Light (MIL), store freeze frame data for later review, and display monitor and I/M readiness status, making it a comprehensive diagnostic solution.

OBD2 Compliance: Is Your Car Compatible with the MS509?
The OBDII/EOBD scanner is specifically engineered to be compatible with all OBD II compliant vehicles, including those utilizing the advanced Control Area Network (CAN) protocol. The EPA mandates that all 1996 and newer vehicles (cars and light trucks) sold in the United States must be OBD II compliant. This regulation extends to domestic, Asian, and European vehicles.
While most vehicles from 1996 onwards are OBD2 compliant, some 1994 and 1995 gasoline models may also adhere to the standard. To confirm OBD II compliance for a 1994 or 1995 vehicle, check the Vehicle Emissions Control Information (VECI) Label, typically located under the hood or near the radiator. An “OBD II Certified” designation on the label indicates compliance. Furthermore, OBD II compliant vehicles are required to have a standardized sixteen-pin Data Link Connector (DLC).
For your vehicle to be OBD II compliant, it must feature a 16-pin DLC under the dashboard, and the Vehicle Emission Control Information Label must explicitly state OBD II compliance.
