No actuator on the diesels, only the V6.
Have you checked the plenum drains? It's the diesels that are most likely to get the engine ECU
(Engine Control Unit) flooded with bad consequences. If not check all the power feeds to the engine
ECU, as the traction light would come on if the traction
ECU (part of the ABS
(Antilock Braking System)) doesn't get the right messages from the engine
ECU.
