Question about 2003 Chevrolet Express
I have had the ABS light come on and stay on on a 2000 Suburban and a 2003 suburban. In both instances the brake system was fine. If you have not done so I would recommend you have the system checked for codes. If there are no error codes and the system is functioning properly the problem with the light staying on can be solved simply. Or at least I hope this solves your problem.
There is a small ground wire that is secured to the top rear of the engine block. It is on the passenger side of the engine. To find it remove the engine cover and reach back to locate the connection. Over time the ground connection gets compromised by dirt, grease, or corrosion. You need to unbolt this connection, clean the surfaces and re-install. On a friend's truck I just reached back and twisted the connection to seat it better and the lights have not come back on.
It sounds too simple but if it works it is much better that giving money to the dealer or a mech to solve the problem.
