Description & Operation: Notes

The Real Time Damping (RTD) system automatically controls vehicle ride by independently controlling a damper solenoid valve in each shock absorber assembly (front and rear). RTD system consists of front and rear adjustable shock absorbers, 4 damper solenoid valves (one located on each shock absorber), 2 front and 2 rear position sensors (one mounted between body and each control arm), ride control switch located on center console between shifter and storage compartment, and RTD control module located in left rear storage compartment. RTD system is equipped with 3 shock damping control settings.

• TOUR (smooth, soft ride)
• SPORT (more responsive to road conditions)
• PERF (full firm position)

The Electronic Suspension Control (ESC) module, controls the damping mode selection according to the following factors. Module uses the following inputs to control each solenoid on each shock absorber separately:

• The vehicle speed.
• Chassis pitch input.
• Steering position.
• Body to wheel distance.
• Ride control switch inputs.

The RTD system does not have a malfunction indicator light, but instead uses the Instrument Panel Cluster (IPC) 20 character vacuum fluorescent display feature to display messages. When a malfunction is detected by the RTD system that sets a Diagnostic Trouble Code (DTC), the IPC will display: SHOCKS INOPERATIVE, SERVICE RIDE CONTROL or MAXIMUM SPEED. The IPC will continue to display message until the system that requested the message sends a Stop Broadcasting Message to the IPC. Message may be acknowledged/cleared by pressing the RESET button when message is displayed except if system requests a continuous message display.
