Hey everyone I have a 05 gmc yukon xl denali. I replaced the brake lines in the truck and since doing so ive been getting the abs light and tc and stablitrac light. I used my scanner to find a c0279 code. I cant seem to figure out how to diagnose this code? It seems people just say to replace the ebcm but i dont wanna spend the money if I dont have to. Ive activated the abs brakes to try to bleed the module but didnt work. Any ideas on what i can do to diagnose this? Thank you

Try pumping up the brakes like you are bleeding them, hold. Then turn key to run, wait a few seconds, key off, key to run for a few seconds, key off. Repeat a few times. May have to bleed brakes if a bubble was in ABS.

Did you cycle key when bleeding? On key on ABS self test cycles solenoid once, if you do it holding brake pedal down an air bubble in ABS.will move. Otherwide you need a pressure bleeder and Tech2.
If this fails to fix it a Junkyard ABS module/Motor is next. Still may need Tech2 to reset.
