Control Module References
This is a "heads up" for those replacing modules on GM vehicles, that may not be aware of Control Module References.
There are a few ways to identify what, if any procedures may be required when replacing modules on GM vehicles.
While the SPS Info tab in TIS2Web can provide the necessary information, those shops that contract mobile technicians to program modules may be able to identify whether a module is "plug 'n' play" or requires programming and set up by another method, if they do not use TIS2Web.
This procedure can be applied to the post below, regarding Glow Plug Control Module replacement by Darren Kling and the need to identify required programming and setup.
Now, I do not use Alldata, Mitchell On Demand or other alternate sources of information in my work, so the reference here is how to determine what is necessary using GM SI. Your experience may be similar using an alternate service information provider.
When completing a module replacement on GM vehicles, at the end of the repair procedure document, there will either be direct reference to a "Programming and Set Up" document, or a link to "Control Module References". The latter links to a table that identifies the steps required to enable module function following replacement.
However, there is a faster way to locate this information in SI than working down to the repair procedure. Build the vehicle and from the quick access tool bar, click on "Control Module References" as identified below, to go directly to the document, which identifies the required process to enable the component to function after replacement.
Of course, there may also be a revised procedure, so checking bulletins for relevance would also be a wise step.
But Marty, that costs $20 for 3 days. How am I supposed to be able to program a module for $45 if I have to spend another $20? It's not available if it's not affordable! I shouldn't have to do this. GM should make it like what I'm used to using. GM should make it so that I can use the library. ;) BTW, I know a guy in Balmor who actually closed his shop up at lunch time so that he could go to…
LOL Guido! Good job the other respondents provided the input regarding alternative sources using the AM SI! Those that would expect it for free wouldn't read it anyway!
Hi Guido, "No, he's no longer in business. An argument can be made that he never was." Ain't that the truth. That should be funny, if it weren't sad, but true.
That’s a gem from the General’s SI site that has saved me headaches in the past. FYI... “Control Module References” are available in MotoLOGIC since it imports SI directly from the OE sources. Here is an example from an ‘18 Camaro. You will see other associated links at the top of the document also.
Very Impressed with the MotoLogic website, what kind of subscription plan do they have?
Contact your AAP or CARQUEST Commercial Account Manager for your pricing. I will say that it's very competitive.
Thanks for showing that option Randy. Seeing if and how the alternative information system vendors offer some of these pieces of useful information can make all the difference for those who are truly interested in getting things right the first time.
Martin, I use GM SI almost everyday and Control Module References is an excellent source for what needs to be done when a module is replaced as you stated. The other benefit of GM SI versus aftermarket information systems is it is up to date with TSB's. PI's, etc. When programming a module I will reference Control Module References but I will also put the module name in the search bar and…
Absolutely true John. The importance of being aware of updates that affect programming is a critical aspect of ensuring that the most up to date information is applied to the repair. As you have alluded, it is important to weigh the options and choose the resources that best serve the customer and charge accordingly. Christmas music and songs are the air already, all be it with modified…
One other way of accessing Control Module References is directly from the OE wiring diagrams. That is also available on most aftermarket SI. The icon that looks like they are telling you to throw a wrench through your monitor is a hotlink to it. See pic Since we hopefully have checked a wiring diagram for proper electrical testing before condemning a module, you might already be at the wiring…
Wow Rich...you have a really old monitor. I always thought it was tightening the bellhousing bolts ;)
I thought it was for adjusting Horizontal Hold.
Good point Richard. There are so many easily accessible options to locate this type of information for those who are interested in and see the value in spending a little time doing the research.
In ProDemand/ShopKey, build the vehicle via VIN or Y/M/M, go to "Service Manual" using the menu at the upper left, click on the "Keyword Search" tab, and type the words "Control Module References" in the "Search Within Manual For" field.
Thanks for confirming that Mike. I suspected that the info would be rolled into the other info systems somewhere, but I do not have remote access off campus to verify.
Hi Martin: Thanks for posting. Good to know. Take care out there. Will be in touch before the holidays. However if not.. Merry Christmas and Happy New Year to you and yours. Sorry but I am an old timer and just have to say the above. I was "Learned" that way. Best Regards. Harley.
Hi Harley! I resemble that remark and raise you.....! Sometimes these "tid bits" of info that are second nature to me, can hopefully turn out to be useful to others. FWIW, I took back "Christmas" many years ago. I never gave it up to tell the truth. Never will a "politically" correct greeting be uttered from these lips, such as "Seasons Greetings"! Take care,
Hi Martin. What more can I say.. You are a PLEASURE to converse/correspond with. A WEALTH of information that you VERY willingly and freely pass on to anyone who shows a TRUE interest. You are right up there with Albin Moore, Harvey Chan (R.I.P.) , Mike Cleary, and the rest of the GREATS whom I respect highly and admire. Keep up the SUPERB work with the GM program. Will be in touch. As always…
You're making me blush Harley! VBG. I have always enjoyed interacting with others such as yourself and our dear friends you mentioned and the GREATS, who care about the trade and those working within, without the influence of personal bias. I have been exceptionally fortunate, at least since entering the dealership realm in 1980, to have always had every necessary resource to perform diagnosis…
