Default Traction Control Light always on.

Traction Control light stays on all the time. Anyone point me towards a solution? I am too inebriated to look for other posts at the moment...

Agreed. Also wiggle the big round connection next to the traction pump around a lil bit. Sometimes that tends to become a lil loose here and there.

It is usually suggested that you pull all the wheels and power wash super well if you don't find a broken wire.

Wash the back side of the hubs if the wires and connectors are corrosion free. However, this is typically for an intermittent fault.

It'* usually a WSS or PMV. WSS'* have to be replaced with the entire hub assembly.

Only the dealer can retrieve TC or ABS codes.

the ones behind the wheels on the wheel hubs. It will have two wires coming out of it. They are on all wheels btw.

Didn't the Snap On scantool we used check the wheel speed sensors? It showed up funky, but we got speed readings from all 4. If so, and if those are the sensors TC uses, couldn't the snap on be used as well instead of going to the dealer? (Not that it helps much, but I know dealers....they'll charge $100 to give you a diagnosis)

It didn't see them on the 95. Otherwise my TC light would be fixed, and Geoff would have driven down with the car.
