Refer to Request Document Instructions section in this document for steps to add additional Parameter/SLOT/SPN sections. Parameter SPN requests are considered to be associated with the closest previous "PGN" section. SAE J2403 should be referenced for guidance with SPN naming.

Preferred Source Address

The J1939 Subcommittee is discontinuing making Preferred Source Address assignments; instead, applications should use Arbitrary Addressing (see J1939-81). Applications will need to request a new J1939 NAME Function if an applicable NAME Function does not exist. If you feel your solution needs a Source Address, then the Preferred Source Address request must include an explanation why arbitrary addressing will not work for the application and why a Preferred Source Address is required.

1. What is the request? Add a new Source Address (Answer 3-6)Revise a Source Address (Answer 2, and changes)

2. Source Address to revise

3. Industry Group 0 - Global, applies to all1 - On-Highway Equipment2 - Agricultural and Forestry Equipment3 - Construction Equipment4 - Marine5 - Industry Process Control, Stationary (Gen SetsCurrent Value

4. ECU-Module Name

Document Filename & Request Submit Instructions

For a more complete set of details on the J1939 Request process, please refer to the 'J1939 Truck & Bus Request Processing Guidelines' document on the SAE Works web site.

Submitting the Request Document

Submit your request by emailing a copy of this Request Form, along with any other supporting documents, to the J1939 Committee using the email address provided below.

Email for Submitting J1939 Requests:

Posting and Sponsoring the Request

If the J1939 Request Form contains only a Manufacturer Code request, then you do not need to post the request document after submitting it.

1.  The requestor is responsible for creating a folder for his / her request on the SAE web site. To get access to the SAE web site, please send a request to the SAE Administrator at the Committee email address listed above.

2.  The requestor is responsible for championing his or her request through the approval process. Please refer to the J1939 Request Process Guidelines document for suggestions on how to do this.

Document Filename Format

1.  Original Request File: filename format is YYYYMMDDii_x, where:

n  ‘YYYY’ = Year (e.g. 2010)

n  ‘MM’ = Month (e.g. 01 = January, 02 = February, etc)

n  ‘DD’ = Day of Month

n  ‘ii’ = Requestor’s initials

n  ‘x’ = Count of this Request Document among all submitted that day by Requestor

For example 20081103TH_1.doc - first request submitted on November 3rd, 2008, by person with initials TH. If two requests were submitted on this same day by the same person, the filename for the second request document would be 20081103TH_2.doc.

2.  Updates to Request File: Use the same base filename (YYYYMMDDii_x) as the Original Request and add an "_R#" extension to the base name, where '#' is the number of revisions made to date.

Original Version: 20081103TH_1.doc

1st Update: 20081103TH_1_R1.doc

Next Update: 20081103TH_1_R2.doc

3.  Support Documents: Use the same base filename as the Original Request and with an "_SUP" extension. Support documents may be included if you feel more detailed text, supporting graphs, diagrams or data would be helpful and should be submitted along with your request.

Request Filename: 20081103TH_1.doc

Support Document: 20081103TH_1_SUP.doc

1st Update to Support Document: 20081103TH_1_SUP_R1.doc

Macros must be enabled for this Request Form to work correctly. Please refer to the Instructions for Enabling Macros section at the end of this document.

'SAE Request Commands' Toolbar Buttons

Use the buttons on the SAE Request Commands toolbar to add and delete PGN and SPN sections from the request document.

For Word 2003, if toolbar is not shown, select View > Toolbars > SAE Request Commands

For Word 2007, the toolbar buttons are located in the Add-Ins ribbon tab.

·  Create New PGN: Inserts a new PGN section. The new section is inserted after the first section that has the selection check box checked.

·  Add SPN After Selection: Inserts a new Parameter/SLOT/SPN section. The new section is inserted after the first section that has the selection check box checked.

·  Create Diagnostic SPN: Inserts a new Parameter/SLOT/SPN section immediately after the General Requestor Information section.

·  Delete Selected PGN or SPN: Deletes any PGN and Parameter/SLOT/SPN sections that have their Selection check box checked. The last instance of an PGN and Parameter/SLOT/SPN section will be cleared, but will not be deleted.

·  Select All Sections: Checks the Selection check box for all PGN and Parameter/SLOT/SPN sections in the document.

·  Unselect All Sections: Clears the Selection check box for all PGN and Parameter/SLOT/SPN sections in the document.

Adding more PGN and Parameter/SLOT/SPN Sections

To add another PGN section or Parameter/SLOT/SPN section, check the select check box in a PGN or Parameter/SLOT/SPN section and then click the ‘Create New PGN’ or 'Add SPN After Selection' in the menu toolbar. The new section will be inserted after the checked section.

Associating new Parameter SPNs with a new PGN

All parameter SPN entries following a PGN section are considered to be associated with the PGN in the closest preceding "PGN" section.

Requesting multiple new PGNs with new Parameter SPNs

When requesting multiple PGNs with new parameter SPNs, one request option is separate request documents for each PGN and its associated SPNs. Another request option is a single request document for all PGNs and their associated SPNs.

When requesting new SPNs for multiple PGNs in a single document, use the document structure:

PGN section (for 1st PGN)

Parameter/SLOT/SPN section (for an SPN in 1st PGN)

Parameter/SLOT/SPN section (for another SPN in 1st PGN)

:

PGN section (for 2ne PGN)

Parameter/SLOT/SPN section (for an SPN in 2nd PGN)

Parameter/SLOT/SPN section (for another SPN in 2nd PGN)

:

Etc.
