Just got back from the dealer.

It's showing a DTC C0711 --Level Control Air Pressure Sensor Circuit code. Cleared it and got the same code again.

The tech wasn't sure what that code means, and thought it needed a ride height calibration, but they didn't have the calibration blocks. I'm no expert, but I don't think that code sounds like a ride height calibration issue.

I have to admit that I was a little bit concerned when they told me that the air spring was broken because it wasn't connected at the bottom mount when they lifted it on the lift. I had to explain that since there was no air pressure in the air spring, it's not expanded. This dealer was a Hummer dealer until about a year ago and is now Cadillac.

Is the pressure sensor on the compressor assembly, maybe in the photo I posted?

Any tips on deciphering this?


Thanks,

John
