Question about Buick Century
There is an intermittent fault with your anti-lock brake system. For some
strange reason GM thinks they need to turn on three warning lights. I
would suspect the fault is with one of the wheel speed sensors. There
should be fault codes stored in the ABS module which can help the service
technicians isolate the cause of your ABS fault.
If you have access to an Ohm meter, each wheel speed sensor/hub bearing assy should have around 1000 ohms of resistance through them with no continuity to ground. If they short to ground, they will set a code. If the resistance is too high, they will set a code. If the hub bearing is worn and the wheel is loose and wobbling, the sensor will not read a valid reading and will set a code.
