So I just got done reinstalling my 350 fresh build on my suburban. 96 suburban k1500 5.7 auto. The issue I now have is a abs light that I didn't have before. The code is for both front abs sensor missing and rear speed sensor. Anyone have any ideas?

what are the actual codes?

I'm not sure what the code numbers are. I stopped down the local chevy garage and had them pull them to see if it was something stupid. They said it is showing front abs sensors missing and a code for rear speed sensor. They told me to check my grounds which I did and everything looks ok. And to check power. Like I said it didn't do it until I r&r'd the engine.

providing the actual dtc would tell you what circuits you need to check. the only power and grds for the abs circuit would be at the ebcm.
