Abs issue

Picked up an 05 with an abs issue. Drove it 1 block and abs seemed to kick on at low speed. Abs and tcs light is on. I found a failed driveshaft support and a noisy rear wheel bearing. I took out driveshaft to fix support and replaced wheel bearing. I unhooked battery and when I restarted nox, the lights were off. Till I hit 5 mph they came back on. I shut off nox and restarted it and lights are off. Is it normal to have no dash lights till you move? I donít think I have seen that. I have not scanned it for codes yet.

Get the BCM and ABS codes. OBDCII will not tell you anything.

Time for a trip to a mechanic with an actual Chevy code reader.

ABS runs most of its internal tests when the vehicle is moving so it can see the speeds each wheel is turning at along with others. The TCS light comes on because its integrated with the ABS, no ABS no traction. There are two solutions right away you can try. One because the vehicle is an 05 look at your ground cable that runs to the ABS Pump. The pump may be losing a ground while it trys to run for a test. The second more likely is one of your other wheel bearings is not working properly and giving off a zero speed when driving. The bearing might be ok but the sensor built in is the problem. As PFarber said, you need to plug in a scan tool that reads ABS codes and it will narrow it down for you. These codes start with a C. Let us know what you find, good luck

i had the same issue on my last equinox. i had the code read at oriellys at it said wheel sensor. i also have a CEL light that will not go out. it shows up when i hook up battery at start. so it sees something immediately.
