What does the slip light mean on a nissan xterra?

The slip light in a Nissan Xterra means that there is a problem with the traction control system. It will usually turn on when the vehicle detects that one of the wheels is slipping and has lost traction. If Your slip light is on permanently then it is usually a problem with a sensor at the wheels. It can also be a problem with the traction control computer. The traction control system works by checking the wheels for any signs of slipping and then cutting power when it detects wheel slip. This can help prevent Your vehicle from losing traction while You are driving. It is also possible that the light comes on when there is a problem with the tires being too bald and not getting traction.
