Description / Abstract:
1. Scope--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.
