Being that EDS is heavily involved in the systems that GM deploys, I asked around and here is what I found out....
Excerpt from Techline link:
Obtaining Broadcast Codes
There are various ways to identify the standard and optional equipment on a vehicle. In this example, well assume you have a 2002 GMC Envoy with a 4-speed automatic transmission in your service bay. How would you describe the transmission?
The model of the transmission is the 4L60E, which is also known as RPO M30.
But if you go to the parts department to obtain parts for that transmission, they will want to know the broadcast code. This is a number which is related to the specific calibrations or running changes in the transmission. During the production year, there may have been a change in a spring calibration or a valve, for instance, which would result in a different broadcast code.
Components that have a broadcast code include engines, transmissions and transfer cases, axles, ECM/PCMs and other control modules, ABS assembly, and others.
Of course, you can always check the broadcast code directly on the component, but that can entail putting the vehicle on a lift, using an inspection light and mirror --you know the drill. Now, theres a more convenient way.
On the Dealer World home page (<http://www.gm-dealerworld.com> ):
choose Service
choose GMVIS
On the GM Vehicle Inquiry System page:
type in the last 8 digits of the VIN and submit
choose Vehicle Component in the page header.
This will bring up a Vehicle Component list.
For each component, you will see:
Component Code
Source Plant
Broadcast Code
Traceability Number
TIP: Use the HELP key to obtain a definition of these terms.
Your parts department will be able to use this information to help obtain the correct parts for your repair.
