Q: What does code P1584 mean?

Cruise Control Disabled. P1584 on Chrysler vehicles means the powertrain control module (PCM) has disabled the speed control system, usually because it detected a fault in the cruise control switch circuit or a related input it needs to allow cruise operation. The PCM stores this code when it commands cruise control off and will not let the system engage until the underlying fault is corrected and the code is cleared.
