C0590 Description

The Electronic Suspension Control Module (ESCM) commands the damper solenoid ON and OFF. When the solenoid is initially energized, the supply voltage is then Pulse Width Modulated (PWM). The amount the solenoid is activated is based on inputs from the driver tow/haul switch, road inputs, position sensor inputs, and the Powertrain Control Module (PCM). The ESCM continuously compares each dampers command state with the state of their feedback circuits to ensure they agree.
