11 J2534 Reprogramming

Reprogramming is often the only solution for problems ranging from driveability and loss of power to
poor fuel economy and emissions related issues. SmartLink C makes it easy. The SmartLink C is a
communication interface supporting J2534 specifications for ECU reprogramming.
Except that the SmartLink C acts as a VCI device and a SmartLink dongle, it also can be used as a
J2534 PassThru device, working together with the PC installed with the OEM diagnostic software to
perform the J2534 reprogramming. In this case, the PC needs to install with the LAUNCH's J2534 tool,
which can be downloaded from www.cnlaunch.com.
