“Pass thru” vehicle re-programming with SAE J2534 device
Pass Thru re-programming over the Internet for 2004 and later vehicles using an SAE J2534-1 Pass Thru device and a laptop PC is available for certain applications. These are listed separately as Pass Thru bulletins. Since these are for specific concerns for specific models, all appropriate diagnostic procedures should be followed before attempting Pass Thru re-programming. Re-programming should only be performed if a technical bulletin provides direction to do so. This technique requires a secure un-interrupted Internet connection and a Pass Thru device that has been recommended for this application

How high is the volume of data transmitted during update programming?
During update programming approx. 4MB are transmitted via the Internet connection. If you do not have a Java runtime environment version 1.5, 1.6 or above installed on your computer, the Java run time environment must be installed the first time you call up update programming. Java version 1.5.0 runtime environment is approx. 16MB in size. Local administrator rights are necessary for its installation on your laptop PC.
Why do I need a permanent Internet link for update programming?
In order to avoid errors occurring during the update programming process it is important to understand that once started, the process can not be interrupted or disconnected and the PC must not be allowed to go into standby, hibernation or similar power management modes.
What happens if I have already paid and an error occurs during update programming?
The update programming which you have purchased can be run from this location any number of times until the process has been successfully completed.
This process is expressly intended for qualified professional automobile technicians. It is possible to permanently damage a vehicle control module if the process is done incorrectly or the wrong software is installed. Be sure to read all service materials carefully and follow the directions exactly.
