Technical Service Bulletin # 00013A
Date: 000301
Recall - Brake Pressure Module Valve Replacement
Product Safety 00013A - ABS EBC325 Retaining Clip # 00013A
00013 -- ABS EBC325 Retaining Clip
2000 Chevrolet 2WD & 4WD Silverado, GMC 2WD & 4WD Sierra, Chevrolet 4WD Extended Cab S10 and GMC 4WD Extended Cab Sonoma
Condition
General Motors has decided that a defect which relates to motor vehicle safety exists in certain 2000 Chevrolet 2 and 4-wheel drive Silverado pickup
trucks, GMC 2 and 4-wheel drive Sierra pickup trucks, Chevrolet 4-wheel drive extended cab S-10 pickup trucks, and GMC 4-wheel drive extended cab
Sonoma pickup trucks equipped with 4 wheel disc brakes. Some of these vehicles have an Antilock Braking System (ABS) motor containing an
out-of-specification spring clip. As the number of ABS stops accumulates, this clip could allow the motor bearing to become misaligned. If misalignment
occurs, the noise during ABS activation caused by the ABS motor will become progressively louder, and retainer/bearing friction will increase, resulting
in higher motor-current draw. Eventually, this could render the ABS non-functional. If this occurs, both the amber ABS warning light and the red brake
warning light will illuminate. The base brakes would remain fully functional, but the Dynamic Rear Proportioning (DRP) system, which optimizes front
to rear brake balance would become inoperative. If the driver were to ignore the red brake warning light, the higher rear-brake output could potentially
decrease vehicle stability during braking that slides the rear wheels. This instability could result in a vehicle crash.
Correction
Dealers are to replace the brake pressure module valve assembly.
Vehicles Involved
Involved are certain 2000 Chevrolet 2 and 4-wheel drive Silverado pickup trucks, GMC 2 and 4-wheel drive Sierra pickup trucks, Chevrolet 4-wheel
drive extended-cab S-10 pickup trucks, and GMC 4-wheel drive extended-cab Sonoma pickup trucks equipped with 4 wheel disc brakes and built within
the VIN breakpoints shown.
