DESCRIPTION & OPERATION
Computer Command Ride (CCR) system controls the firmness of vehicle ride based on driver selection, vehicle speed, lateral acceleration and lift/dive. CCR control module controls an electric actuator in each strut. The actuator rotates a selector valve that has 3 different sized orifices. The position of the selector valve affects the firmness of the strut damping characteristics. (Scheme 11)
Actuators are an integral part of strut and are not serviceable separately from strut. System has self-diagnostic feature that stores codes in control module memory if system fault occurs. See SELF-DIAGNOSTICS .
Scheme 11
OPERATION
If CCR system detects a fault, a code is set in control module memory and both LEDs on select switch are illuminated (when a code is not present, one LED illuminates indicating switch position). LEDs will remain illuminated as long as fault is present. If fault is no longer present, LEDs will go out but code will be retained in CCR control module memory. As long as a code is set in memory, system performs a one-second self-diagnostic test every 3 minutes and whenever select switch position is changed. During this one-second self-diagnostic test, both LEDs will illuminate. If fault is corrected, LEDs will go out. If fault remains, LEDs will stay on.
