Why Is My Toyota RAV4 Check Engine Light, VSC, and 4WD On?
Your Toyota RAV4’s Check Engine Light, VSC, and 4WD indicators could be on due to a range of issues from a loose gas cap, faulty oxygen sensor, or problems with the anti-lock braking system to more complex concerns in the vehicle’s emissions, stability, or four-wheel-drive systems, signaling the need for a professional diagnostic check.
