Circuit Description

The Continuously Variable Road Sensing Suspension (CVRSS) module monitors a lift/dive signal at the Powertrain Control Module (PCM). Under normal conditions, the CVRSS module supplies a 5 volt reference voltage to the PCM. The PCM grounds this circuit when the vehicle is accelerating rapidly or braking hard. When the lift/dive signal goes low to approximately 0 volts, the CVRSS module commands all four CVRSS dampers to a FIRM condition.
