詳細(xì)介紹

PassThru (SAE J2534) DLL

SAE J2534-1 API is the "Recommended Practice for Microsoft Windows 32-Bit Application Programming Interface for Pass-Through Vehicle Reprogramming". Vehicle manufacturers will be required to provide a Windows software application for reprogramming their model year 2004 and beyond vehicles using a J2534-1 capable interface (e.g. CarDAQ-Plus). This standard and associated EPA requirements will give all vehicle service/repair facilities, not just dealers, the ability to perform in-field ECU software updates.

In addition to reprogramming, J2534 supports diagnostics and calibration. The API provides protocol-independent functions to: read and write messages, establish periodic messages, perform filtering, and assert ECU reprogramming voltages.
