C0592 Buick Code - Right Rear Solenoid/Motor/Actuator Circuit

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 Rear Solenoid, Right Rear Solenoid harness is open or shorted, Right Rear 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 C0592 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.
