Test Conditions

The RSS module monitors damper solenoid circuit on both sides of coil during off, on and Pulse Width Modulation (PWM) portions of command signal. The RSS module expects to see high side feedback high and low side feedback low when valve is off. Consequently, it expects to see high side feedback low and low side feedback high during first one-millisecond of the on period and high side feedback low and low side feedback low during the rest of the on period.
