2005 Chevrolet Silverado abs brake light on .... came on when I put a smaller tire size on when I got a flat. Recently I changed the wheel hub out with a new sencer.. lights still on . Mechanic says it is both the wheel hub and abs module.are bad . I tend to dis agree sence I just changed the wheel sencer. He said there is no signal from the wheel sencer. Can anyone help me figure it out?

 

Check the wiring to the sensor and the connector to make sure there is a good connection and no damage to the wire as far back as you can check.. Do this on both front wheels.

 

Yes I have checked the wires according to the mechanic the code is the rt front sencer but that has been changed
