12 J2534 Reprogramming Using SmartLink C

Flash programming has become a common and profitable procedure in the repair and service of today's vehicles.
As part of the 21st Century Tune-up, 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 designed to support J2534 specifications for ECU reprogramming.
Except that the SmartLink C can act 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
the official website at www.cnlaunch.com.

12.2 As a Remote J2534 PassThru Device

Besides local ECU reprogramming, remote ECU reprogramming function is also supported using SmartLink C.
*Before diagnosing, please make sure the following conditions are met:
• The SmartLink C device is connected to the Internet and has a strong network signal.
• The OEM diagnostic software has been installed on the PC.
• The LAUNCH's J2534 tool also needs to be installed on the PC. This tool and its associated operation instruction
documentation can be downloaded from www.cnlaunch.com.
Ensure that the remote reprogramming operation is performed after the SmartLink C is connected to the vehicle's
DLC port and the Internet, and has been switched to the super remote diagnosis mode. For specific operations,
please refer to other associated documentation.
