Ok first off this is a 03 2wd 1500 Silverado, I'm posting in here because the sister site is super slow for some reason and system is essentially the same, I changed the front pads this morning, all I did was c clamp the calipers install new pads, put wheels back on, started it up pumped the pedal a few times and now I have the service brake system message, no abs light. Connected tech2 and it shows no dtc of any kind anywhere, so I'm lost, fluid was not low but I added about 6oz just to see, no change, any ideas? Doesn't seem like it would be the abs module.
