Hello, I recently programmed a Buick with GM SPS2 software. 2 minutes into the programming, it failed. Now the ECU is a no comm. I would like to know if anyone on here could share the boot pin location on this module. Service number is 12583827 and Hardware number is 12582720. Vehicle is a 2005 Buick LeSabre. I am editing because I was just informed that this is a P04 not a P01. Maybe only way is by JTAG.
