Description / Abstract:
This Technical Information Report defines the diagnostic
communication protocol Keyword Protocol 1281 (KWP1281). This
document should be used in conjunction with SAE J2534-2 in order to
fully implement the communication protocol in an SAE J2534
interface.
Some Volkswagen of America and Audi of America vehicles are
equipped with ECUs, in which a KWP1281 proprietary diagnostic
communication protocol is implemented. The purpose of this document
is to specify the KWP1281 protocol in enough detail to support the
requirements necessary to implement the communication protocol in
an SAE J2534 interface device.
