Leveling Suspension Failure

[drstephensugiono]

Rebuilt my air suspension pump from ECS Tuning and still inoperative. Could it be the suspension module?

Do you have Durametric? When I did mine I had to drive a few miles to get it to kick in. Heard from another guy who said he had to go through the suspension leveling/ride height procedure in Durametric to get his to work. When I started my '06CTTS in place the pump wouldn't turn on, I took it out of the shop and drove a few miles and I head the pump start to kick on and all was well. Came back and cleared the stored code and been like new ever since.

How's the fuse for the compressor under the left hand seat?

[drstephensugiono]

I will check the fuse. I borrowed my friends module and place in my car, failure light still on and still didn't work. tried my module on his car and Leveling Suspension Failure came on his dash. so we put his back in his car and his car was fine. question is.....why does mine still have failure light with his good module?

[drstephensugiono]

I have checked the 40A fuse under the driver's seat by the battery and it was fine. Tested the pump directly with 12v and it works. I suspect that when putting a good module you still have to reset with durametric? HELP

Hopefully somebody around you has Durametric. Put a post out for Durametric help in your area in the title and see if someone responds or just go out and purchase the Enthusiast version.

The valve block which lives with the compressor has sensors which have known to play up.

Fault code readout is what you need.
