J2037_200106
The utilities defined for J2037 are designed to facilitate manufacturing and service diagnosis requirements. Definition of the capability includes definition of standard messages and the dialogue necessary to provide the capability. The standard messages will be distinguished by the contents of the first data byte which specifies the diagnostic operation. Note that some vehicle applications will not require the implementation of all the defined diagnostic capabilities, and consequently, these applications will not support all message modes.

J2054_200106
This SAE Information Report describes the diagnostic data communications required for implementation of a set of diagnostic test modes for all electronic systems on the vehicle's serial data link. These test modes can be used by off-board test equipment for both service and assembly plant testing. The goal of this document is to provide standard methods to perform common functions for all electronic systems. This standard set of procedures will aid development, production, and field service of those systems.
