Hi I have a 2010 prerunner single cab with a mild lift, that is pretty well cared for and never abused. Today while driving i noticed both the check engine light (not maint. req. light), and the slip indicator light on at 33,968 miles. I pulled over to check engine oil and fluids and everything looks ok. The coolant is on the low side but still above the low mark on canister. It was raining heavily last time I took the truck out, and I used the auto LSD and stability control for the first time.
I rely on this truck heavily, so this has me very concerned. Any ideas what this could be? Thanks.
