Pass-Thru Extended Feature - Base Document
J2534-2/BA_0500_202201
SAE J2534-1_0500 defines the pass-thru interface requirements for the reprogramming of emission related control modules.
The SAE J2534-2/X_0500 document set adds extensions to the SAE J2534-1_0500 API (version 05.00) specification so that the API can be used for features not covered in the SAE J2534-1_0500 specification. Together, these features provide a comprehensive framework for a common standard, to protect the software investment of the vehicle OEMs and scan tool manufacturers. There is no required for an SAE J2534-2/X_0500 pass-thru interface to be fully compliant with SAE J2534-1_0500. SAE J2534-2/X_0500 interfaces can implement some or all of the features specified in the SAE J2534-2/X_0500 document set.
This document must be used in conjunction with the SAE J2534-2/RE_0500 document.
Rationale:
Each of the features contained in the original SAE J2534-2 document (API version 04.04) is being published as a separate document for ease of maintenance and extensibility. At the same time, these features are being updated to be compatible with SAE J2534-1_0500 (API version 05.00) and to address feedback received from the field.
