Default Height Sensor problem

Today on my way home I had a suspension fault 30mph pop up. Dropped the lr3 to bump stops. By the time I got off the road it had wore through the inner fender and through the foam on the rear ac lines. I connected my iid tool and got it back to standard height somehow and it displayed vehicle raising slow or something. Checked faults and got this...Using IIDTool BT V3.0 B2712

When I ran it right after it happened it showed something about the rear right height sensor but did not show it right now.
Can anyone look and tell what is going on? And if it is a height sensor can I pull the plug and drive it until the new sensor gets here?
thanks

A few things.

If you need to drive it right away, you can pull the EAS fuses under the hood and it will be fine. The problem, is that you need to recalibrate the EAS. You can do this with the IIDTool, so you're in luck. Before you do that, you'll want to understand why it lost its calibration. Start with that right rear corner. Inspect the sensor and the associated wiring. Is the bracket holding it bent? Is the wire harness/connector compromised? If so, fix that and recalibrate. If not, just recalibrate and see what happens.

What I can tell you is that a Cross Articulation error is 100% a symptom of a bad calibration. What I cannot tell you is why your calibration went **** up.

Good luck....the good news is that the solution is all within your grasp and even if you fit a new sensor, that's not terribly expensive.

^ I tend to agree. Shockingly all those errors you have are pretty much background stuff. Odd that the one critical error is gone now, the one for the specific sensor. It could be a failing sensor, which would also trip an articulation fault.

Ok so that give me hopefully a trip to work tomorrow then I can recalibrate tomorrow after work.
Little but of back story is it did sit on jack stands for 2 weeks while I was doing brake lines. I’ve never once had a suspension fault before then.
After I did that took a trip to TN and while sitting in a parking lot the car went into extended mode for no reason but did not lift. Just on the dash. Cut off the car and did not think about it. Monday was on the way back from lunch and had the standard height only message then went off. Then today turned on my road and had the max 30 message and dropped to bump stops. Ate up my fender well and there you have it.
Possibly the calibration being jacked up due to sitting on stands for 2 weeks? I will have to check the sensors cus I could have bumped them when doing the lines?
also I’ve never had all those faults or that many anyways.

How did your finder well get messed up? That can only happen with the wrong tires.

Do you have sensor extension rods installed?

I’ve got 32 and yes I do have rods on it. I installed them awhile ago and was in the process of trying to figure out how to remove them and use the iid tool for the lift. When it went to bump stops the inner fender well and the tire made friends!
The rod removal got postponed due to brake lines corroding and replacement.

I figured, thats why I asked. When the vehicle drops to the bumps with rods you are way out of spec, the sensor is basically not reading anything anymore. Therefore you can not recover unless you do a guided calibration with a GAP Tool and lift each corner manually (but dont save the settings) or use jacks to get it started off the ground so the sensors can read. I do wonder if having it lifted for so long with rods also did no good by putting the sensors out of spec for that time, prob not but ya never know.

Yea you are probably right. But when it dropped today that was the first I have experienced it. I was almost home and pulled off in my yard. Then connected the gap tool and sone how got it to raise up. Not exactly sure cus to be honest I was a bit foggy brained/pissed!

The GAP tool seems to have some ability to ignore errors and basically manually operate the air ride, thankfully!

Yes very thankful! That is by far the best piece of equipment. An I only can use comfortably probably 2% of its capabilities!
