So, we went playing in on some trails alone the beach dunes a few weeks ago (don't worry they were designated just for that so that we did not harm and dune grass) with my newly installed winch up front. Anyway. I was in off road height, and in mud and rut mode. I dropped the right front into a dip and the dash made the classic dinging sound and the info displayed something about normal ride height only. It was still moving in mud mode and we were close to a good flat spot so I drove it that way for about a 1/4 mile. No other issues. Shut it off, started it back up and all was fine. we drove home ast highway speed, no issue.

Fast forward to today while in a VERY HOSTILE environment - the grocery store parking lot- I am amazed at how much harder the speed bumps seem with the which out front. I was not straight on and hit the speed bump with the right front wheel first and you guessed it, same ding, light and warning as a few weeks ago. Both front struts/airbags are less than 4 months old. They are Arnott brand and seem to be as good as the last pair I put on and ride quality is about the same as before I mounted the winch.

When it quits raining (sometime in the fall of 2023?) I plan to pull the connector on the right front ride height sensor, check the wiring and goo it up with dielectric grease and re-install.
I will then recalibrate the suspension with the iiDTool.

Question is...... could it be as simple as the front sensor be about to go out, or is there some other more complex (expensive) diagnosis in my near future?

Could be just that simple or a chaffed wire

 

That is most certainly a possibility. Also, I got to thinking about what would make the suspension get unhappy and thought maybe the wheel speed sensor could have an effect. I will pull it and clean it up when I have the wheel off this weekend looking at the sensor (and wires)

Steering angle sensor being out of calibration has dropped mine to the bumps

 

What is the code? That will probably tell you what is up. If you have rods installed on the sensors, then it could easily be pushing a sensor out of range causing an issue.

 

No code. Just am message in the dash saying normal ride height only (or some such). Turned it off then back on..... all is fine.

PlNni g a long beach trip this weekend, would like to find the problem BEFORE the trip, not during.

 

That message would generate a code.

 

Your right, it should have stored a code. and I should have looked for it, but I turned off, back on and drove home and forgot about it. As they say " after further review" I found this:

C1A11-64 (28) Pressure increases when system inactive - Algorithm based failure - signal plausibility failure
( on 09-05-2021 01:02:53 at 137767 mi )
*Confirmed
*Test Failed Since Last Clear

AND

U0138-87 (08) Lost communication with all terrain control module - Bus signal/message failure - missing a message
( on 19-04-2021 13:13:49 at 137462 mi )
*Confirmed

Anyway, a new problem has presented itself. When I was changing the oil, I noticed a very small leak under the right axle seal at the end of the short casing. Well the axle shaft was out about 1 1/2 inches. Like a dummmy, I grabbed it and pulled and it came out even further. No keep in mind, that I pull it up on four ramps to do fluid changes to keep it level, but now I needed to remove a wheel, and what ever else I hade to to push the axle back into the diff.

I figured it out, but got to wondering if I did that during my three wheel stands at the sand dunes the week before. either way if the axle was not connected properly, the wheels speed sensor might be unhappy while in sand mode.

Either way I will keep looking.

That code generally implies that an airbag is leaking back into the gallery OR the reservoir is. Either way you likely have an internal leak or defective pressure sensor. Bets are on an internal leak at a solenoid block.

Second code about communication, ignore. Those ghost errors come up a lot and are only a problem if they are a problem....

That is really, really weird about the axle. You mean the diff axel rod itself and you do not mean the CV joint (inside the boot?) That can really only pop out if it was never installed right to begin with. The CV would slide out long, long before the retainer clip would let go. Or the retainer clip was never installed? If you had to slam it hard to reinstall, well then it would be there. My concern would be any sorta spline damage to the diff or shaft. As for causing a side issue with suspension, I dont see how. It would just float at the CV joint and the wheel end would still be fixed properly at the axle nut. So that end of things would not even "notice" the issue unless the shat pulled out all the way at which point you would not have traction at that wheel. But then you would have really messed up the splines by that point (metal shavings/noise).
