Ok, this warning means there is a problem with the electronic suspension system. could be something minor to a major problem. the first thing to do is to have the electronic suspension module scanned for trouble codes. a trouble code would give us a much better idea what the problem is. unfortually this system requires a high end scan tool like a GM tech 2 scan tool, normally used at the dealer. here is how the system works.


The RTD system is bi-state real time damping system. The Electronic Suspension Control (ESC) module controls the suspension damper solenoids and suspension position sensors, along with parts of the automatic level control (ALC) system and electronic variable orifice (EVO) power steering system.

The RTD system consists of the following:

ESC Module
Compressor/Leveling Module
- Air Pressure Sensor
- Exhaust Solenoid
Compressor Motor Relay
Steering Handwheel Speed/Position Sensor
Electronic Variable Orifice (EVO) Solenoid
Suspension Damper Solenoids
Suspension Position Sensors
