About 6 months ago my VSC and VTRAC lights came on in my 2004 4Runner and I can’t find out what is causing them to go off. If I scan using an OBD2 scanner it gives me a “Catalytic Converter operating below threshold”

As you may know, the CEL triggers the VSC and traction control light, so the problem is not in your ABS system. Now, going back to the main issue:H ow many miles on the truck? Did you check for the exhaust leak? How are the oxygen sensors (Sensor 2)?
It has 222,550 miles and I haven’t checked my O2 sensors yet but ik that sometimes the Yaw Sensor can trip itself and you fix that with a zero point calibration. I will try that first and if not then check the O2 sensors?
