Two problems related to brake abs warning light have been reported for the 2004 GMC Sierra. The most recently reported issues are listed below.
I have a 2004 GMC Sierra and all of a sudden my airbag light and abs light came on took it in to have it looked and the airbags are not communicating with the sensor and they would have to go more in depth on the abs but to go more in depth they charge $80. 00 an hour just to be able to figure it out. I have seen similar responses on the airbag light for this vehicle please help.
Abs brake activates at slow speeds. Wheel hub bearing problem.
