According to my buddy who is a ase certified mechanic yes they can, but most of the time they will tell you that they cannot due to the fact they would rather make the markup on a new module and the installation, hope this answers your question.
Dealer only
You don't, the dealer or repair shop does.
NO......only Chevrolet dealer can program control modules, snap-on scanners can only collect data from modules not put data in. some shops other than dealers may have that capability but price wise it would be the same as dealer.
It must be programed using special equipment like a Tech II, used by dealers.
I had to have my bcm replaced. I was told that it was due to car being jumpstarted which is another issue. I had to take it to the dealer with a cost of replacement being $600
Unplug Battery for 10 minutes. BCM issue. Not sure on original cause. It is normally due to a software bug in the bcm. The dealer can flash New software into the bcm to correct the problem.
Hook up tech 2 tool download the BCM information unplug it from the car, go to the dealer computer plug in tech 2 open up program for soft ware down load follow screen promps,after tech 2 is down loaded plug it into the car and down load new soft ware to the BCM. NOTE: make sure car battery is charged up before down load.
under dash left side bolt to firewall with bracket tcm and seperate bcm boxes
Available at the dealer, he will have to program it.Available at the dealer, he will have to program it.
Take out the old BCM and replaced with a used one with similar number. It worked for me in Chevy Mailbu. It costed me only $20 whereas dealer was asking $800. My car worked after spending $20 for BCM module from Junk Yard. Ensure you take old BCM module and match the number
My first suggestion is to have the Body Computer (BCM) checked for codes. Chrysler has released a software update for the bcm that the dealer can perform that fixes a lot of lock complaints on 2005 vans.
It should be under the dash between the radio and accelerator. You can change it yourself, but it will have to be programmed by a dealer or mechanic.
