My 1997 chevy 1500 4+4 5.7 liter
Dear MW: Why does my
ABS light come on. Brake paid are good. I check all
connection seem to be okay. Truck brakes good to. Cant figure why light
came on. Help thanks!






MW:
If the ABS light comes on, there should be a code stored in the ABS computer.

Your truck may have an open recall for the front speed sensor mounting area  
corroding, causing improper air gap between sensor and the hub reluctor ring.
A common symptom is that the ABS activates at slow speeds, and while hitting the  
brake pedal and turning (parking lot maneuver) Call local dealer with the VIN # and  
they can tell you if your vehicle needs the recall.

If no recall, the next step is to have the system scanned for trouble codes.
Other common faults are the front hubs or sensors themselves. Also the rear wheel  
speed sensor in the transfer case.

ABS / Anti lock brake warning.
The anti-lock braking system (ABS) uses several sensors, motors, and a  computer in conjunction with the normal braking
system.
The
ABS regulates the brake pressure in order to reduce wheel lock-ups.  Reduced wheel lock-ups improve the driver's
control of the vehicle during  braking.
Improved stability and steering enable greater control of the vehicle in the  case of an abrupt stop.
The ABS operation is available from 5 km/h (3 mph) to the maximum vehicle speed.
A warning light means a problem was detected, and the system needs to be  scanned for codes in order find out the area the
fault is in. With the light on,  ABS operation is not present, but normal braking is.
The
Traction Control System is controlled by the ABS system.
