Control Module

The CCR control module is a computer used exclusively to control and monitor the CCR system. It is attached to the floor pan located below left front seat. The control module receives speed, lift/dive and lateral acceleration switch input and determines the optimum mode strut valving for current operating conditions. The control module also receives feedback from the struts to determine proper system operation. If the control module receives an incorrect feedback signal an error code will be set in CCR memory and a "SERVICE CCR SYSTEM" or "SERVICE SSS" message will be displayed on the Driver Information Center ("SERVICE SSS" applies to vehicles built in 1993). For diagnostic purposes, grounding the Diagnostic Enable circuit will cause a Light Emitting Diode (LED) on the control module to flash error codes.
