So before i got my beloved cobalt back on the road a month ago, i went on a weight reduction frenzie, and like the artard i am, i removed the onstar module in a happy go lucky fashion from the rear deck, between the speakers. i thought it was only for XM radio but perhaps i am wrong and it is also onstar.

Mechanic is pulling BCM codes for onstar communication.

He had suggested a while back that my issue could have to do with onstar, considering it was taking a while to start, and when it was on i was getting ''low coolant' and 'power steering' warnings on the dash.

well finally, the car died on me in the middle of nowhere and has refused to restart. funny.

anyway, any input here, to satisfy my curiosity? i will be bringing the module to the mechanic tonight and hopefully tomorrow i hear good news haha.

if this is the case, i guess its just funny how it ran for a week without it and now will not run.

If it ran for a week without it then it is likely not necessary. Network codes to non powertrain modules shouldnt affect the powertrain.

 

I believe that module had theft deterrent stuff in it perhaps it didn't imediately cause issue but after a while it noticed?
They wouldn't sell them to the general public unless it was an insurance claim back in the day.

 

According to this thread it will not run without the onstar module

Slapbet is probaly right makes sense if a thief could just disconnect it that wouldn't be good

 

Slapbet, im kind of with you lol. Really stupid lol.

 

Damn gub'ment spying on me.

 

i have an onstar module if you happen to need it.

 

It will need to be flashed with the vin if you do pick one up.
I'm assuming you still have yours though.

 

Seems to be a lot of issues with your car, hope you solve them soon

 

Yeah i brought mine to the mechanic, really hoping that by some act of god that this is my problem lol. If so its just funky that it ran for a week without it haha.

 

Nevermind, it didnt work

 

If the module is bad i have one ready to ship.

 

thanks; we should be okay.
