What's wrong, in plain English
On these Ram 3500, 4500, and 5500 trucks with the Cummins 6.7L turbo diesel engine, the engine control module may contain a misaligned capacitor. That capacitor can short-circuit, causing the engine control module to lose communication internally. Dealers will replace the engine control module to fix the problem.
What you should do
Contact a dealer, or call FCA US customer service at 1-800-853-1403, to schedule the replacement.
The engine control module replacement is free of charge.
