Hello, I’ve been having intermittent issues for almost two years with my GXP going into limp mode. It starts with the Red X, Contact Dealer, ABS fault, Brake fault and ESP disabled. I get nothing but second gear and one I shut it down, that’s it.

Trips to the dealer and local mechanic finally got me some info. They knew there was something causing a break in the high speed canbus. ECM was replaced in January. Three months later it happened again. Local dealer traced it to a short in the Onstar/Bluetooth VCIM. I located a replacement with the same part number on eBay.

I noticed though that one pin on my original VCIM was bent down. I bent it back. See pic. The pin with the blue arrow was bent almost touching the red

Now see the connector with the corresponding holes. The red is where the white wire is supposed to go and it’s melted. I think the pin above caused the short and melted the whole thing.

Where would I find a replacement for this connector? I think that’s all I’ll need.

As best as I can find, is that its shown as a connector from manufacture called Yazaki. It has a P/N of 7283-8621 an seems to be available from them. But I'm sure there are some sharpies on here that know how to get "that" connector from a known local source (an for a reasonable price). The service manual W/D shows only 7 wires installed, an that white wire is "not" one of them. Maybe that wire has something to due with the activation of the Bluetooth (that finally came online from the factory) on the MY09 GT an GXP's

My car started doing that about 6 months ago too. Every CanBus error in the world, then it will do fine for a month or so. Following to see what you find.

Do you run an interceptor gauge or any kind of monitoring device on your OBD2 port? Mine has only ever messed up when something was plugged into the obd2 port (which used to be all the time, until I unplugged my gauge). I've had the gauge unplugged and no HPTuners cable plugged in for going on 2 months now to see if it will ever mess up without something in there.

So far no luck finding that particular connector for sale other than the $50 piece with pigtails on Rock Auto. Most places that have just the connector are minimum 1000 pieces or $1000 orders.
I’ll keep searching but I might end up biting the bullet and getting the $50 harness

To 383_Stroker: I have an Innova OBD2 scanner and a BlueDriver wireless. I only started using these after this all started happening. I don’t leave either plugged in. Early on I could stop and start the car and read the codes. Lately it had gotten so bad that the code readers couldn’t detect the CANBUS at all. When I called Onstar to get the codes, they couldn’t read them either. Likely because the Onstar device was offline.

Jacob does the connector have any marking on it? I looked up the terminals that go in it according to GM and those are a good number that come back to TE number 175266-5 - That is the 040 Multilock II series of connectors. I found a 12 position one but it does not seem to match up with yours. Drawing below:

12 Position 040 Multilock II

It looks to me like a JST connector I have seen before. So any markings might help.

Actually found on a GM truck board that the pigtail connector ( 88952886 ) was associated with a different part number than is listed with our pinouts. an OEM of 15431365 brings up an Aptive (formerly Delphi) number that just by the crude drawing on Mouser looks close, but there is no drawing on the data sheet. And only seems to be available in large quantities.

Aptive 15431365

So apparently they are in a 2008 silverado, might be able to find one of those in the junkyard.

Actually the listing on Rockauto seems to say there is one of these connectors in just about every car out there!!

Thanks! That drawing on the TE site looks like mine. Hard to tell on the Aptive drawing.
The connector has no markings but there looks like there’s a locking piece on the side opposite the clip that holds it in the module.

Hi all, I think I found the part number for that individual connector. I ordered a sample of the 175965-1 connector above from TE Connectivity and it turns out it was too narrow. No loss.

I finally found some markings on the connector “2 AMP 11408 7”. Extremely hard to see! I searched for that and got a hit again from TE Connectivity: 917975-6. I studied their drawings and measured the opening on the VCIM box and it matches. One of the drawings actually had a view that even showed “2 AMP 11408 7.”

Hard part is finding one now. TE doesn’t show stock for these so I can’t order a sample. Most of the other sellers have a 2400 minimum on qty.

Yea the quantities are always the stumbling block. I have had to resort to some Chinese knock offs before for things and if I had a choice I would rather use a used connector from a junkyard and clean it up. BUt here is a smaller quantity supplier:


Payment, tracking and reliability is always a sketch factor using these suppliers.
