I asked about this in a thread a few days ago and got no response, so here's a simplified version. I'm getting an intermittent out of range front left height sensor voltage error. (The voltage is too low - see image below of readings.) I've changed the sensor and replaced the pigtail connection to it with no change. When I get the error the height indicator on the 4x4 display drops down low, and I get a solid yellow suspension light and a flashing yellow headlight symbol on the dash.
Where does the wiring run through the car for this sensor and what module does it go to? Would appreciate any diagnosis tips and the location of the wiring diagram in the manual for this system. Thank you!
Note: I've also been having off and on brake light switch errors (I've replaced the switch with an OEM unit) and loss of cruise control function. When I get these additional errors the suspensions drops.

 

I'd go through the height calibration process with the GAP tool. Especially when the height sensors are touched, the computer can get funky readings and error out trying to adjust to level, even if it already is level.

Doing the calibration steps will stop that

 

Yes, I've done the calibration a few times, but no change.

 

Did you replace the pigtail with the Land Rover splice kit or just the connector itself? I ask, because sometimes those wires that run from that sensor to the main bundle can get yanked out downstream and since they are covered with plastic conduit or tape, it maybe difficult to detect.

This happened to me on a trail once. It was a pretty unique and severe situation, geometrically, but anyway my big *** tire got stuffed up into the wheel well and tore down the wire bundle (even though I'd moved it to the top of the rail) and the wiring got severed within the main splice well AFT of the sensor. The symptoms were similar to your description, except that everything still worked. I could still use Off-road Height and all that, I just had a yellow suspension fault and a flashing AFS indication. Also on my 4x4 info screen the front left wheel was "wonky" compared to the other three.

 

I used the splice kit, which had about 6" of wire attached to the connector. Haven't gone wheeling or had any situations in a long time where the wiring would have been stressed by the wheel dropping too low.

Anyone know where I can check the wires further upstream so I can see if it's a wiring fault or a module possibly?

 

By the way, the vehicle has had its share of wet passenger footwell issues (via sunroof and A pillar) in the past.
I guess I will be diving back in to the repair manual to try to trace this wiring. Probably spent 10 or 15 hours researching this online (everyone needs a hobby right?) and haven't found a single clear mention of exactly where the sensor wires go....

 

Finally found the wiring diagrams section buried in a folder of my repair manual files woohoo!

 

would you mind sharing the diagram with me?
and did you ending up fixing the low voltage issue?

 

Did the wire diagram help remedy the issue? I’m finding myself in the exact same situation with no light at the end of the tunnel.
