I was having new key fobs programmed and while using bluetooth programmer communication was lost.
chime went, all door locks unlocked, dash gauges all went to zero, then power to cluster and OBD port went out.
I removed the bcm, the programmer was still plugged in, and power returned to the OBD plug.
I went to upull and removed bcm, tcm, ecu, radio and instrument cluster from a 2011, mines 2010.
I thought these would be all of the modules with vin programmed, but upon installation, still no power.
I thought that since previously when bcm as unplugged power returned to OBD port, I would unplug the bcm again, and voila, power returned to OBD plug.
All fuses check ok.
Any idea what else could have been fried when communication was lost?
Are there any other modules with vin programmed?
Sorry for the long post but I have only used one tank of gas since purchasing the vehicle then this happened.

 

When the dealers program a fob they (are supposed to) put a charger on the battery to ensure adequate voltage throughout the process.

 

To start the fob is matched to the RCDLR NOT the bcm or BCM. You should be able to just start over.
Would have been cheaper to go to a locksmith or GM dealer or get a fob with a programming module.

 

I did get a fob with programming module, Autel AP 200, lost bluetooth communication with module, fried everything, don’t know what else has been damaged.

 

I have read so many stories about disappointments with those fob modules. I had a terrible experience with an incompetent locksmith but I think most of the ones that do fobs are probably fine. I keep promising myself a scan tool capable of doing it. What I have learned is that dealers all charge different prices, and at some it's negotiable. Be nice to your local service manager(s.)

 

The module I meant is not bluetooth. From Dorman. I don't know how the other modules got involved, the only thing being synced is the RCDLR.
Does the TPMS still read out? Same module.

That Dorman programmer was the first one I used, programmed ok but I got key fob battery low on DIC.
I changed the battery twice, same result.
I read on this forum that it was likely a problem with the fob included with the programmer so I returned it.
If you would read my initial post, I do not have power to anything with the large red connector installed on the bcm.
If I unplug that red connector I only have power to the OBD port, as seen by the light on the programmer coming on, but I can’t do anything because there isn’t power to anything else, no cluster power, no lights, no anything but the light on the programmer.
It would appear that something else down the line was damaged, maybe shorted out when communication was lost, but I have not been able to find out what else should be replaced.

 

The battery low is because the fob supplied is stupid, it would have been fine with a genuine GM fob. I always recommend getting a Genuine fob when getting the Dorman. Dorman supplies different brands of fob circuit boards, some work some don't..

Which power was lost? The car or the programmer?
Have you checked the fuse next to the battery? That powers the BCM computer.
Try pulling fuse #23 on the BCM, that controls the RCDLR, maybe that is the short.

You used a module and procedure I don't know anything about. I got no ideas.

here is a list of the X4 connector (large red)

All car power as lost.
Thank you for the pinout chart, haven’t been able to find any detailed wiring diagrams on the interweb.

 

The reason I posted it is to show that nothing you did should directly affect that plug, besides a short somewhere else. Possibly the RCDLR, which is the module being programmed; actually matched much like bluetooth pairing.
I have no idea what your Autel does.
So, when you were programming the car suddenly blew up, the Autel was fully powered and the plug to the OBD port was not touched?
At exactly what point in the programming did the car blow up? Did you think you were supposed to do something in the BCM? What directions were followed?
