Seizing front brakes.
So long story short. I was removing alternator the line from the battery to the alternator hit the brake line that goes from the abs module to the line lock, arced and sparked and blah blah.. So replaced the line and bled the system. drove maybe a mile and the front brakes were locked to the rotor.. i finally got it back to house and swapped out the line lock, bled the system again thinking the line lock was messed up from the arc, nope got stuck again and the car thru all these codes as i tried to get back to the house. SO basically right now.. cars on jack stands right now,, I pump up the brakes a few times.. the fronts will be completely locked up, and the backs still spin normally.. all the codes are below.. Is it possible the abs module or ecbm lost programming or is that bad boy shot and needs to be replaced?
Lost communication with engine control system.,
P0575
p0703
p0856
Control module communication buss off
Lost communication with ABS control module
""" Also just dawned on me. I was talking to Schpenxel and i remembered that some times when i get on it driving the car would just brake by it self for a split second and go away.. only after i got on it . either moderately or hard. wondering if that has something to do with this as well.. This was happening way before the above happened. It never threw any codes for this auto brakin issue.

Shop manual does not show a way to reprogram the module, either that or I can't find it. I would speed the $100 to have these guys look at it. https://www.myairbags.com/product-ca...TTE&_year=2008
Also, you may want to disconnect the ground when working with live power cables, but it sounds like you had the problem before the cable grounding that took place.

When I lived near you, I use to get parts from SMC. Sometimes his prices are good and sometimes they are high. He buys the end of production leftover parts from GM. https://www.smcautoparts.com/ His name is Sean/Shawn.

If I replace the ecbm and abs controller do I have to have it purged and reprogrammed? Wouldn't I be having issues with the rear wheels locking up as well if it was the ecbm. And what's with the lost communication with engine system and no communication on ECM with my hand held?
