What does the lightning bolt mean on a 2005 dodge ram?
On a 2005 Dodge Ram, a lightning bolt symbol usually indicates a problem with the powertrain control module (PCM) or a related system. This isn't a specific code, but rather a general warning light that lets you know there's a problem that needs attention. You'll need to have the vehicle scanned with an OBD-II code reader to get the specific trouble code(s) to diagnose the issue. The problem could range from a minor sensor issue to a more serious engine or transmission problem.
