Check Engine And Trac off Light Toyota 4Runner: Expert Fixes

To fix the Trac Off and Check Engine light on a Toyota 4Runner, pressing the traction control button may restore functionality. However, if the check engine light accompanies the Trac Off light, there may be a deeper malfunction in the safety system.

Faulty wheel speed sensors or low tire pressure can also cause the check engine light to come on with the traction control light. While it is generally safe to drive with the traction control light on, if the anti-lock braking system light and red brake-warning light also illuminate, the entire braking system may be affected.

The TRAC Off indicator light means the traction control is turned off, and to turn it back on, press the button again.
