The wrench light on a 2017 Toyota Yaris is equivalent to a check engine light in another vehicle. The light indicates a problem with the car, which could be caused by various issues. Instead of trying to find a random issue, it is more practical to take the car to a mechanic for a diagnostic scan using an OBD tool. This will reveal the trouble code and pinpoint the problem for repairs. One simple thing to check before going to the mechanic is the gas cap or fuel door, as a loose cap or open door can trigger the light unnecessarily. Be sure to verify this before seeking professional help.
To turn off the wrench light on a 2017 Toyota Yaris iA, you must use an OBD II scan tool to erase the code.
