well i am stumped i changed my frontbrake pads on my 99 seville sls when changing I noticed that the right front pad sensor was ripped off no ccode came up before but ok. changed pads code change brake pad came on soooo i said well maybe i need to change the rears as well. sensor still on bought a new brake pad sensor and cleared all codes...shut off car and restarted code still came up tried a few times and repeated erase codes. the pads are fine front and back all the other sensors are on right. what the heck please help the dealer is toooooo expensive for something stupid

 

Try disconnecting ground cable on battery and leave it off fora few minutes. Sometimes this helps erase codes in history etc...Reconnect and see if it still codes.

 

thank you, actually i called another state cadillac dealer who specialized in cadillac repair and he said sometimes you have to disconnect all 4 sensors and clear all codes through the obd 2 system then replug them in. and restart your car.....wouldnt you know it worked. this is a great web site

 

excellent information to keep around.
thanks

 

Did you really have to get all sensors disconnected then obd2 to clear then connect them again?

 

My first try would be the battery for 5 minutes before I went any further.

 

yes i had to disconnect all the sensors then go to the obd 2 go to all codes then clear all codes you hear the computer kick on then it will say all codes cleared. then replug in your sensors and restart you car.. i know pain in the *** but it works
