2008 grand caravan, Dash warning lights: Brake, ABS, esp bas and the traction control icon are all activated.
I have the same issue. I hope someone can comment with some answers.
This just happened to me. My mechanic said that it is due to unreliable wheel speed information. It can be caused by having different diameter tires on the van, but more likely due to a bad wheel bearing or a wheel bearing starting to go bad. He was able to get a fault code to identify which wheel sensor was the problem. Since the wheel speed information is bad, the ABS and traction control are disabled, hence the warning lights.
This just happened to me. I reset the computer by taking the neg. battery cable off the battery for about 3 or 4 minutes and put it back on the battery. That fixed the problem for me.
