I have a 2003 Dodge Grand Caravan with 90K miles. We had a terrible ice storm and then snow last night and today. While I was pulling into the parking lot at work I was sliding/skidding a bit on ice. My ABS and brake light came on. I have not had any issues with it not working and it was working fine earlier.

I assume I can chalk this up to adverse weather conditions?

 

No. Anytime the warning light is on is due to some type of failure that will lead to the system not functioning properly. You must have someone with mechanical aptitude and proper equipment to accurately diagnose the cause of the light being on. Anytime the ABS light is illuminated, the system is shut down and will not function. A quality code reader is a necessary tool to determine the root cause of the failure.
