P0596 Severity
Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.
For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.
Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.
The cruise control servo is electronically controlled by the engine computer (PCM). This servo controls the vacuum that activates and deactivates the cruise control system. If the Cruise Control Servo does not operate as requested by the PCM, code P0596 will set.
