I have a 2014 international prostar. The abs module light is on, the upside down triangle light is on and a light that says TC with a circle around it is on. Any ideas of what the issue is?
Likely a abs wheel speed sensor or wiring short. The tc with the circle is your traction control indicator. Your traction control uses your abs wheel speed sensors so if there is a problem with them your traction control light will come on too
