I have bigger things to worry about now, read on if you like...

The patch job in my original pics of that CV boot lasted about 200 miles before being flung off by centrifugal force. Grease in every nook and cranny.
We stopped in Coeur d'Alene ID looking for a split-boot repair kit. It doesn't seem like one is available anywhere. All the part numbers that said split-boot led back to a standard boot.
I ended up using a 10' roll of self-fusing silicon tape and Gorilla tape over that and so far so good. We're now in Jackson.

But now I've got this

Out of nowhere while cruising at 70mph the dash lit up:

Suspension Warning Indicator
Orange Brake Light
General Fault (!) ? (The one with the exclamation mark)

With the message center showing:
-HDC Fault - System Not Available
-Special Programs Not Available
-Suspension Lowering

It lowers, not to the bump stops and I can still drive but it's driving us mad. Restarting the truck and adjusting the suspension "fixes" it for about 10-20 miles then it all happens again.

I have a new AMK compressor arriving at an indy shop here in Jackson today for install tomorrow but I'm not completely certain this is the main issue. It's an original Hitachi but hasn't shown any major signs of impending failure. My front valve block leaks but not much at all.

I'm also going to install my spare brake light switch and check the bulbs.

Anything else? I read that it also might be a height sensor or the battery, of course. I'm cruising at 13.4 Volts - good enough? It's an Interstate MTP 49 - less than 6 years old. I think 3 years old actually...

Ugh. Other than this new development, the LR3 has been a joy to drive on this trip - but we still need it for daily excursions and to get back to Seattle.

 

Need to get the codes read to be sure what the system is complaining about.

How much do you want for the old compressor?

 

I wonder if you have a leaky air bag; or other air leak coming from somewhere.

 

Battery voltage sounds a little low, but probably not low enough to be the culprit. Sounds like a classic brake light switch, but a wheel angle sensor can result in the same symptoms. If it were a sensor your calibration would be hosed and you'd be getting (red) cross-articulation faults...so it's not likely to be that.

 

IID tool is pulling:
C1B00-61 (2B) Steering angle sensor - Algorithm based failure - signal calculation failure

and my steering wheel is now about 30º off center to the left but the truck drives straight

I'll have the shop adjust the tie rods and check for what caused my steering wheel to go so far out of whack.

Can the steering angle sensor cause all my symptoms?

 

I've recently heard that it could.

 

Yes, it can. I've had that issue before. In my case it was after an off-roading trip. Start the video at about the 00:27 mark.

 

So the next question is hard without seeing the steering components, but can adjustments fix this? Since my steering wheel is sooooo far out of whack, I'm assuming a nut or bolt came loose... (tie rods ends?)
Reason I ask, there's no way this shop will have a replacement sensor and we'll need to move on the next part of the journey soon.

I guess things could be worse than having the suspension lowered the rest of the trip. It still allows me to do full speed so no big deal I guess.

 

I assume you don't need a sensor. Once they figure out why the wheel is crooked just calibrate with the IID Tool

 

Looks like you knocked the snot out of the steering.

So did that break the sensor and cause the same odd warning lights I'm seeing?

Any reason to think I should also look at the height sensors?
