C0584 Buick Code - Right Front Solenoid Circuit Open

Quick Answer

The strut actuator is controlled by the Continuously Variable Road Sensing Suspension (CVRSS) module with a Pulse-Width Modulation (PWM) signal. Common causes include Faulty Right Front Solenoid, Right Front Solenoid harness is open or shorted, Right Front Solenoid circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code C0584 Buick Description

The strut actuator is controlled by the Continuously Variable Road Sensing Suspension (CVRSS) module with a Pulse-Width Modulation (PWM) signal. Switching the voltage ON and OFF at a high frequency, or pulse width modulation of 2.0 kHz, controls the amount of current delivered to the actuator. By controlling the amount of current to the actuator the CVRSS module controls the damping force in the strut. A higher level of damping force is achieved by providing correspondingly higher current levels, relating to higher percentages of PWM duty cycle. The default damper state, no battery voltage is one that provides a minimum damping force. The CVRSS module periodically commands each strut actuator to a preset PWM duty cycle in order to override the normal PWM command. During this preset PWM duty cycle, the CVRSS module is able to perform a diagnostic test on each strut actuator to determine if a malfunction is present. The preset PWM command can be either an OFF or ON state duty cycle.

2. What are the symptoms of a C0584 code on a Buick?

Common symptoms include a suspension warning light on the dashboard, a rougher ride, or the vehicle sagging or leaning on the right front side.

3. What causes the C0584 code to appear?

The most common causes are damaged wiring, a faulty right front suspension solenoid, corroded electrical connectors, or issues with the control module.

4. How can I diagnose the C0584 code on my Buick?

Start by inspecting the wiring and connectors for damage or corrosion, then use a multimeter to check for continuity in the solenoid circuit. A scan tool can also verify communication with the suspension control module.

5. Can I drive my Buick with a C0584 code?

While the vehicle may still be drivable, the suspension may not function properly, leading to a less comfortable or less stable ride. It’s best to address the issue promptly.

6. How do I fix the C0584 code on my Buick?

Repairs may include replacing the right front suspension solenoid, repairing damaged wiring, cleaning corroded connectors, or updating/reprogramming the suspension control module.

7. How much does it cost to fix a C0584 code on a Buick?

The cost varies depending on the specific issue but may range from $100 for wiring repairs to $500 or more if the solenoid or control module needs replacement.

8. Can a weak battery cause a C0584 code?

While uncommon, a weak battery or charging system issue can potentially cause electrical faults, so it’s worth checking the vehicle’s battery and alternator.

9. What tools are needed to address a C0584 code?

You’ll need a diagnostic scan tool, a multimeter for testing circuits, and basic hand tools for inspecting and repairing components.

10. Can I clear the C0584 code without fixing it?

Clearing the code with a scan tool is possible, but if the underlying issue isn’t resolved, the code will likely return.
