Optional Pass-Thru Features J2534/2

<p>SAE J2534-1 defines a standard vehicle network interface that can be used to reprogram emission-related control modules. However, there is a need to support vehicles prior to the 2004 model year, as well as non-emission related control modules.</p><p>The SAE J2534-2 document meets these needs by detailing extensions to an SAE J2534-1 specification. It is not required for an interface to be fully compliant with SAE J2534-1 specification to implement some of the features specified in this document. Together, these extensions provide the framework for a common interface to protect the software investment of the Vehicle OEMs and Scan Tool manufacturers.</p><p>Only the optional features will be described by this document and are based on the December 2004 publication of SAE J2534-1.</p>
