1. Requirement Wording Conventions And Document Issue History
1.1 Requirement Wording Conventions
Within this document the following conventions are applied when describing specific compliance
requirements:
The word “Shall” is used in the following ways:
1. To state a binding requirement on the GMLAN network, or the nodes which comprise the network,
which is verifiable by external manipulation and/or observation of a node or the network.
2. To state a binding requirement upon a nodes requirements document that is verifiable through a review
of the document.
The word “Must” is used to state a binding requirement upon nodes on the network which have a
corresponding node requirements document. These requirements will be verified as part of the
component verification.
The word “Should” denotes a preference or desired conformance.

Initial Draft
Reformatted tables and styles used within the document for consistency.
Corrected error in CAN Identifiers section to show the correct range of reserved CAN Id’s
for physical diagnostic request messages.
The following modes have been modified from the initial draft: $04, $10, $12, $27, $28,
$3E, $84, $AE.
05Oct98 Modes $10, $20, $28, and $AE were modified along with the global data dictionary table
05Oct98
to reflect a single flag for disabling DTC’s during enhanced diagnostics.
Each Appendix was separated into a separate sub-document and revisions were made to
the diagnostic communication matrix appendix.
Added a chapter to document Flash Programming Process.
05Oct98
20Nov98 Deleted the NetworkConfiguration service $84 and created DIDs to replace the
functionality.
20Nov98 Modified All Appendices to reflect changes from October 1998 Co-Location.
20Nov98
Accepted revisions to all services from October Co-Location and changed all the CANIds
to match the latest reserved ranges. Changed all of the “S” values in the convention (Cvt)
columns of the tables to “M”. Changed all consecutive frames after the initial flow control
frame to have a PCI value of $21 (per ISO 15765-2).
20Nov98 Reordered the initial sections of the document prior to the test services for better
readability.
20Nov98 Made several modifications to the $AA service description, pseudo code, data dictionary,
and allowed negative response codes.
20Nov98 Made several changes to the chapter describing the module programming procedures.
The global pseudo code table was modified to add a column for power up initialization
20Nov98
values. There were also changes to some of the global variables in the table.
There were changes to the negative response code section to not have a negative
response code $11 sent if the request was functionally addressed. Response code $33
was eliminated.

Revision History
A new appendix was added for diagnostic addresses.
Service $10 was modified to eliminate two levels previously defined and to add a new
level which impacts whether or not diagnostic trouble codes can set while device control is
active.
The following services had some technical changes: $1A, $20, $27, $28, $34, $3B, $A2,
$A5, $AE
15Jan99 Modified the pseudo code to modes $AA and $AE
15Jan99 Modified sections prior to test modes in order to get the field codes in the document to
update correctly.
15Jan99 Modified each diagnostic service to have the format of the communication matrix
consistent.
15Jan99 Revised Appendix C
15Jan99 Modified references to application timeouts within this specification to point to the
appropriate timers described in the application timing parameters section of this
specification..
15Jan99 Revised the chapter on communication layer interaction
15Jan99 Revised the section documenting CANIds reserved for diagnostics and general diagnostic
implementation rules.
15Jan99 Revised the diagnostic communication matrix appendix.
15Jan99 Revised the section regarding the diagnostic application timers.
15Jan99 Modified the table of supported DTC status bits to differentiate between Emission, safety,
and other types of devices.
15Jan99 Updated the chapter on diagnostics and node management
15Jan99 Created Appendix D containing information on ECU diagnostic addresses.
15Jan99 Created Appendix E with the DTC Status Bytes and Fault Type Byte (Symptom)
definitions. Removed the DTC Status Byte bit definitions from mode $A9.
15Jan99 Modified the functional system extended addresses to include only those identified as
standard at this time.
15Jan99 Modified the Negative Response Code section of the specification
15Jan99 Revised Mode $27 to allow additional seed/key pairs for ECU manufacturing and vehicle
assembly plant testing needs
15Jan99 Modified Mode $A2 and $A5.
05Mar99 Reformatted the diagnostic services sections to new format as agreed upon in
Rüsselsheim at December co-location.
05Mar99 Updated the Diagnostics and Node Mgt section based on updates to the GM LAN
Communications Strategy Specification (GMW 3104) version 1.4.
05Mar99 Modified modes $A2, $28, and $20 along with the global pseudo code data dictionary
05Mar99
05Mar99
section to accommodate the handling of service ECU’s
Added new Appendix F to describe the Manufacturers Enable Counter and the
Vulnerability Flag. Deleted sections of $27 service describing these variables. The
Diagnostic Network Configuration Matrix appendix has now been renamed to Appendix G.
Added figure which depicts the relationship between the various GMLAN specifications
per the request of the Steering Committee.
Added a new section describing diagnostic requirements for wake ups.
05Mar99
05Mar99 Moved Negative Response Service Definition section to a separate chapter.
05Mar99 Modified services $20 and $A5 to add timing requirements for switching in and out of high
speed operation on the Single Wire CAN link.
05Mar99 Modified service $A9 descriptions, pseudo code and verification procedures.
05Mar99 Modified the Introduction, Mission, and Scope sections.
05Mar99 Modified the chapter on document structure to include definitions of sub-function and
data-parameters.
