Question about 2005 Chrysler Pacifica
What does it mean when the ABS signal light comes on ?
The front left and right ABS wheel speed sensors need to be replaced together. If you just replace the drivers side or passenger side, the light will come back on. If you are experencing ABS shutter, or when you apply the brakes, the ABS unit will activate the affected wheel, causing a horrible noise and feeling in the brake pedal/ steering wheel, one or both of the sensors are transmitting confusing data back to the pcm, causing a false " wheel lock signal" activating your ABS module.
These sensors are fairly easy to replace for someone that has done car repairs. I did both of mine on a Saturday morning, took 3 Hrs. I would only replace them with genuine Chrysler parts.

Whenever the ABS warning light comes on in the instrument cluster and it stays on it means the systems electronic control module (computer) has detected a problem in one or more of the inputs to the module; an ABS fault code is present as long as the ABS light is on. So what must be done to correct this? You must have the ABS electronic control module scanned with a special tool to read the fault code, and then a trained technician will diagnose and repair the defective part or wiring. Most times this is a wheel speed sensor (one for each wheel) that gives an erratic signal. While the light is on all you have is regular non-ABS brakes.
