Default ABS & Brake Lights, Traction Control Off, Service Suspension

The ABS and brake warning lights illuminated, Traction Control Off feature, and Service Suspension DIC (warning) all appeared at the same time.
Computer scanned for errors which indicated a faulty ABS senor, driver front which was removed and replaced the driverí* front wheel bearing. I cleaned the EBCM and all four ABS sensors wire connectors and treated with dielectric grease. I reset the computer by detaching the vehicle battery connectors for an hour however the same errors re appears. Checked voltage at the drivers ABS wire connectors (unplugged) read .05 volts black wire and 5.0 volts white wire. Voltage when ABS wire connected, 2.5 volts black wire and 2.6 white wire. Any other recommendations, I do miss having ABS and Traction Control.

Connect your DVOM to the sensor you just replaced and set it for mV/AC or millivolts A/C. Jack that wheel up and spin it. You should see a voltage on your meter. The faster the wheel spins, the higher the voltage. If you see no voltage, then the sensor is not seeing the tone ring.
Once that is verified working correctly, you may need a scan tool to clear the ABS codes and then depending on the computer, it actually wants to see all the sensors working, so you will need to drive the vehicle for a bit.

Mike, since he replaced the hub/sensor, I think he has a harness problem.....

He said he disconnected the battery for a awhile. This doesn't clear codes last I knew sir. Codes need to be commanded to be cleared. Then a self-test cycle needs to be completed.

I am having the same issues with my 2007 Chevy Silverado I just replaced a driver side wheel bearing and the brake and traction control light will come on periodically.

Forum etiquette dictates that if you don't have anything useful to add to the thread, its best not to post anything at all. It just adds distraction.

Mike, I don't believe you have to clear the codes....The ABS module will do a self check, the instant you turn that key on.....if it passes the self check, those codes will go into history, and there won't be a hard code...

So if he replaced the correct hub, and the ABS light was still coming on, I am leaning towards a harness....

But you are correct, I don't think you can clear codes, current/history, by disconnecting the battery...
