    i have a 1998 Buick century and i have a DTC code c1276 and i need to know how to fix it and what i need to replace thanks.

    RE: C1276 is a problem in the ABS brake solenoid valve for the left front. You could have a problem in the brake pressure modulator vavle assembly. A valve may be sticking or shorted internally, or a wiriring problem in that circuit. You would need a schematic and do resistance testing on the wiring and the solenoid to determine where the problem is.

    That code is for an open or shorted left front solenoid valve. The diagnosis can be tricky for this problem, as it can be a number of different things causing the problem. The big items that can go bad and cause this issue are the Electronic Brake Control Module, which is basically the computer for the ABS system. Also, there could be a problem with the solenoid valve itself which is part of the entire modulator valve. Both of those parts are very expensive and should not be replaced until they can be verified there is a problem.

    A couple other smaller things that can be faulty can be the ABS fuse is blown or a problem with the fuse block. Unfortunately, you’re probably looking at one of the more expensive parts, since they are the ones that usually go bad. To properly diagnose, though, I would have it looked at by a technician.
