Report: Locked up WCM may cause engine cranking problems
Dodge Ram 3500 Problem
Average Mileage: 45,990 mi (30,000 mi - 61,980 mi)
If the engine does not crank (or cranks but won't start), the wireless control module (WCM) may have locked up. This is due to static discharge through the ignition key. A revised model should be installed, but simply disconnecting the negative terminal of the battery for thirty seconds will temporarily reset the module so you can start the car.
