Hello. I do not know of any WCM module that will cause the engine to lock up. If the engine is locked up, then there is a mechanic failure in the engine. I usually try spinning the engine over by hand to see if it moves. If it does not, then the engine will need to be replaced. If the engine can be moved, then there is another issue. A no start on this vehicle can be caused by a number of things including a failed ASD relay. If you are going to have this fixed, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose the no start and have this issue addressed correctly.
