The Maxiscan Ms509 Obd2 Scanner is a valuable tool for both professional mechanics and car enthusiasts alike. This handheld device is engineered to demystify your vehicle’s health by providing quick and accurate diagnostics. Compatible with all OBDII/EOBD compliant vehicles from 1996 onwards, whether they are US, European, or Asian makes, the MS509 empowers you to understand and address car troubles efficiently.
This robust scanner supports all nine OBDII test modes, ensuring comprehensive diagnostics for even the most challenging issues. It grants users easy access to engine-based EOBD fault codes. The CAN-enabled technology delivers clear and concise DTC definitions directly on its generously sized, backlit LCD screen. Navigating the complexities of generic P0, P2, P3, and U0 codes related to engine emissions, as well as manufacturer-specific P1, P3, and U1 codes becomes straightforward. Beyond simply reading codes, the MaxiScan MS509 is capable of turning off the Malfunction Indicator Lamp (MIL), commonly known as the Check Engine Light, and it stores crucial freeze frame data for in-depth analysis at your convenience. Furthermore, it keeps you informed on monitor and I/M readiness status, essential for emissions testing.
