The electronic ride control is not working. Rear of car is too high and there is no dampening in front shocks.

That means errors had been detected previously and stored in history. If the error did not reoccur, the currect DTC would not show them.

How did you get the trouble codes? They do not seem to be in the correct format.

RS0027 is rear right damper solenoid valve open circuit. Could be due to a faulty solenoid valve or a break in the wiring circuit.
