Sorry. It's was 3 to 11 at 19 not 3 to i
Curious if we're seeing these issues on the later model LR4's yet?
The issue was the headunit went bad. The shop is going to take the unit apart to see what failed. The headunit failing caused all sorts of other issues. Its amazing how integrated these trucks are.
Hopefully the next gen will have some intelligence built in.
@jymmiejamz I’ve been having some odd things happening lately and many of my codes are communication related. I’ve rebuilt my compressor and replaced the leaking plastic drier cap with a metal one, but it’s not to say the compressor still isn’t on its way out. I need to drive around with live values and see if any height sensors are out of whack.
To rule out any can bus fun I ran your tests and got the following:
Bat voltage off: 12.39
Bat voltage run: 14.16
Running
Volts at 3: 2.65
Volts at 11: 2.33
Bat disconnected Resistance between
3 and 11: 62.3
3 and ground: 11500
11 and ground: 10500
Bat connected engine on or off, resistance between
3 and 16: 0
11 and 16: 0
While driving a few times we have gotten an air suspension fault. It says I’m in extended mode sometimes but it doesn’t appear to be. This has happened in normal and off Road height. Last group of codes were:
c1131-92
u0132-87
u0159-87
slew of ventilation codes
Let me know your thoughts!
Thanks,

COILS!!! wait till you have to drive 2miles on the bump stops, never mind 800Thanks!
Early summer I rebuilt my compressor and changed the drier desiccant preemptively and a month or so later started having problems because It seemed to run for a long time so I wanted to try and get ahead of it.
I’ve had a few issues this summer. First time after a lot of rough dirt roads I stopped for a break and while idling was getting a bell saying I was in extended mode but I was in normal. I lowered to access and then to normal height and it cleared that, but then shortly after that I had an air suspension fault and icon saying normal suspension only. I don’t recall the code but was able to search the net where I was parked and it was one that was saying the compressor wasn’t keeping up. Cleared the code went on my way and it came back on the way home, suspension fault dash light and normal mode message.
Next day looked closer at the compressor, thinking maybe my rebuild was bad and discovered the crack in the plastic cover. Replaced that with the metal one and I was all good for awhile.
Then a few weeks later one a easy dirt road in off road mode I kept getting random extended mode warnings. I could lower and go to normal and it would be fine.
I had one real rough rocky river gravel trail a few weeks ago and no issues at all. I really gave the air suspension a work out and no errors or weird extended mode warnings.
A couple days ago my wife was driving back from MT in the cold temps and on the flats going 65 got the air suspension fault normal mode and light. She pulled over in a few miles and shut the vehicle off and started it again and gone. The pics attached are of the codes I just pulled and I assume are related to the event. Funny to see the vent system ones because my wife was saying it was acting odd, blowing cold when it was set to 80.
So a few things going on. Haven’t driven it since she’s gotten back. I’m going to drive it Tuesday to an appointment and see if anything happens. 150k on the clock now and still the original bags. I bought the o rings to rebuild the valve blocks. I get sagging if it sits for more than 5 days. haven’t done that yet but don’t think it’s the problem.
thanks!
