I had to make some advasive maneuvers yesterday to avoid rear ending someone. I locked up the brake a bit, but then let off of them and went into the shoulder of the road (30mph at the most) and it really wasn't all that bumpy. About a mile down the road my diff light came on, now I was in 2wd. I pulled over and turned the truck off and recranked the truck and it was off. I started driving home and it came on again and right after that happened the diff light turned off and the ABS light came on and the SLIP light. It didn't feel like anything was activated. ANY IDEAS?????? I was only about a mile away from home so I just drove home.
