Q: What does code P1587 mean?

Cruise Control Clutch Control Circuit Low. P1587 on Chrysler vehicles means the powertrain control module (PCM) has detected a low-voltage condition on the cruise control clutch control circuit, which is the electrical path that tells the PCM whether the clutch pedal is pressed. The PCM expects a specific voltage on this circuit and sees it pulled below the acceptable threshold, so it stores the code and may disable cruise control.
