Mine just came on last night and won't seem to go off bythemselves! Is there a correct way to fix them without diconnecting wires! Before I replaced the mastercylinder and booster about a month ago they would come randomly and I could pump the pedal and they would always go off! Since replacing them they have not come back on until now! Any advise would be greatly appreciated! thanks! Dan

 

Have you checked for ABS codes? Info is in the sticky.

 

Thanks soo much for the help!

 

Well what was wrong with it?

 

if this is in the 92 truck and you have an exhaust brake Check your exhaust brake for vacuum leaks in any of the hoses.

 

There is a vacuum looking canister mounted on the drivers side fender, there is a vacuum line going to it from the vacuum booster. If there is a vacuum leak in the line( the thing sends a low vacuum signal to set of the brake light if it fall to 8.5 hg) if you have a vacuum leak, bad hose ect. it will make the brake light come on. That is probably the problem.

 

Unplugged the connector behind the glove box and waited for it to reset and everything is back lovely with No lights on! Thanks for the help guys!

 

what connecter? maybe it will fix mine!!! But then it'll be totaly dark !!!!!!yepps!!!
