System Outputs

CVRSS DAMPER HIGH-SIDE
The high-side of each damper solenoid is connected to the Continuously Variable Road Sensing Suspension (CVRSS) control module. The control module controls the voltage on these lines via a relay ("RTD Body" Relay).

CVRSS DAMPER LOW-SIDE
The current delivered to each actuator is controlled by a method known as Pulse Width Modulation (PWM), in which the battery voltage command to the actuator is switched on and off at a high frequency (2.0 kilohertz). The actuator current is a function of the duty cycle, or percentage of time that the battery voltage is applied. The default damper state (with no battery voltage, and thus no current, provided to the attached solenoid actuator) is minimum damping force. Higher levels of damping forces are developed by providing correspondingly higher current levels, relating to higher percentages of PWM duty cycle.

ICCS2 DATALINK OUTPUTS (LEFT AND RIGHT)
A measure of the road surface is sent from the CVRSS control module to the Electronic Brake And Traction Control Module (EBTCM) at four discrete levels via two data lines (circuits 960 and 961). The EBTCM uses this information to detect rough road conditions while braking, eliminating false, unwanted ABS cycling. This allows for more aggressive braking when stopping on rough roads.

ICCS2 data is passed from the CVRSS control module to the EBTCM via a PWM method at a frequency of 333 Hertz.
