1Universal Diagnostic Tool: The car fault tester is a fast and reliable diagnostic tool that acts as the link between the vehicle and the computer. Equipped with a unique multiplexer technology, which can be used in all types of vehicles regardless of voltage levels and communication standards. 2Sound and Light Warning: When the scanner is connected to the vehicle, the device will check the vehicle's battery voltage and automatically adjust it to the vehicle's 12 or 24 volt voltage level. If the voltage is too high or too low, scanner will give an audible and visual warning and be reminded by the battery icon in the diagnostic software. 3Multiple Obd Functions: Such as adjustment and programming, there are detailed instructions and help texts to assist your diagnosis. You will find step?by?step information about the prerequisites, preparations, and implementation of various functions; even the most complex functions can be performed simply. 4Rapid Detection: Read and erase fault codes and Slr all systems; view real?time data, graph and save real?time data. Component activation. Ecu coding/parameter adjustment/component configuration (new component initialization, particulate filter regeneration, diesel injector coding, Tpms, etc.) 5Intelligent System Scan: Complete scan of all Ecu/Ecm on the vehicle platform, configured by the system. Complete vehicle information, allowing vehicle?specific inspection of Obd functions without being connected to the vehicle.
