Abs engine light vsc lights are on cause data was erased with diagnostic reader

it's possible that the reader was not exited out properly. Those instruments are so picky with how you exit out the system, etc. Secondly, with a Toy 4 that old, I'd change out my coolant. What happens with old coolant is that it creates a static charge and can easily interfere with normal sensor activities. Coolant is a baby almost and has to be babysat. I would change every 8 to 12 months. I have a vw that uses G12, G 60 also work well, which I've been on now for several months. good luck
