I don't do much software installation in my small shop, and after a failed flash on a Ford BCM a month ago I'm in need of a confidence booster. Diagnostics confirmed internal PCM failure on a '08 silverado 6.0L, I've got new OEM PCM coming to the shop today. Anything special I need to be aware of when flashing this unit?
piece-of-cake?

Easy. I recommend windows 7 64 bit or windows 10 64 bit. Just make sure it's a laptop that has nothing in it. Use it only for Flashing. Have battery charger connected and do PCM flashing first. Then do Anti-theft, That's it! Easy! Good Luck!Comment

Hey Bob I found it. Its in the module menu. Kind of confusing. Once software is installed I had to go back through the SPS menu like I needed to flash another module on the same vehicle. At the bottom of the module selection list is the theft relearn option. I did not cycle the key correctly the first time after performing the security relearn so I am running it again with the instructions to cycle key off for 2 minutes and then turn to on position and wait 15 seconds before attempting to start.Comment

Attempted security relearn again without luck . What step am I missing? After I completed the 12 minute countdown I exit SPS and cycle key off for 2 min. Then I turn key on to run position for 15 seconds before attempting to crank. Security light stays illuminated.Comment

I am suspicious of faulty TDM (theft deterrent module) now. I wonder if TDM has been my issue the whole time?! Initially I did send ECM to local module repair shop which confirmed internal ECM failure before condemning ECM. I am leaning to replacing TDM now, any suggestions welcome. Thank you.Comment

a piece of cake? ... It's definately a Piece of Something
May the Piece Be with you.
The OE's lately have been getting kinda Anal with the key security BS. Maybe you could try to reprogram all the keys off line off a Maxi Cyst or a SKP 900? Are you sure some of the provided keys aren't just clones off another key and cannot be programmed by normal means?Last edited by Witsend; 10-11-2017, 12:39 PM.Comment
