Safe to drive? HDC Fault and more

[Silmarillion]

We were driving down the highway and all of a sudden all these faults triggered. The speedometer went to to zero and all the dash sensors where flashing. Vehicle suspension also lowered. The adaptive front lighting system sensor is also flashing. We took it into Auto Zone and they said there was a right front wheel speed sensor fault among other things. Just got 265/65/18 KO2 tires 2 weeks ago - - I don't know if a tire cut a line or something. I've used the IID tool to lift the suspension close to a normal level. We have 3 hours left on our trip. Do you think we're in danger of doing damage to the vehicle?

The battery is at a good charge and all the exterior bulbs are functioning properly

Did they wipe the codes and scan again for what would come back?

I personally think it will be fine. Take it easy and I wouldn't go above 60 as a safety barrier.

You mention the IID tool. In case you didn't know, you can clear fault codes with that.
If it was something anomalous, you should be fine. If problems recur, you'll have a shorter list to scroll through. Good luck.

The tire should not be a worry at the right front. There is a small chance you could damage a loom on the left front, but it doesn't sound like that's the issue. It would be helpful to know what the faults were. If it happens again use your gap tool to read them and make a note so we can try to figure something out. Then you can clear the codes and proceed. If you haven't cleared the codes in a while before the problem today the Autozone guy likely found a bunch of stored faults but most would be irrelevant. But assuming he did clear them you will at least have a fresh base line to work from if it happens again.

I cleared those codes again here is what came up when I refreshed.

I hope you find the cause, A lot of times, the newest vehicles are not wire endurance tested for continuous off road conditions, allowing premature failures of the wire connectors and sockets due to vibrational issues. That sucks, but hopefully you find the cause. It is frustrating for a vehicle nowadays to shut down and become undriveable, due to stupid sensors that have absolutely nothing to do with the engine and drivetrain.... kind of like the newest faults with BMW's where water in the trunk goes down to the steering control computer, and causes fire, and locks steering..... All because BMW never thought about the fact that people have to open trunks in the rain, and lots of water then gets into the trunk area, unavoidably.... geesh... that is a class action waiting to happen

OK I got in and found that the speed sensor wire was stripped by the rim of the wheel or the tire. 30$ amazon part. How hard is it to replace this?

Anyone have instructions?

 

[Silmarillion]

The local repair guy said 39 for the part and about $100 for labor, based on what it said on the diagnosis info. Doesn't sound too bad.

Destin Florida area.

I would let them do it. Sometimes it's not worth the hassle of dealing with stuff yourself.

I would also figure out how the wire got broken in the first place. They should be out the way and safe from contact with wheel and tyres.

Blanket complaint about general use of electronics in vehicles doesn't really belong here. Keep it on topic. LR's track record with regards to the Ford and Tata vehicle years has been good. They run fine off road.

Glad to know it was just a bad wiring loom. Common occurrence that tire/brake shops don't put them back correctly so of course they spring free and rub. No idea on the difficulty to replace though. If you're lucky it might be similar to the brake wear sensor and there's a plug behind the wheel well liner.

Not too difficult. A 4 out of 10

Its fairly simple and takes about half hour. You need to take out the wheel well to get access to the plug located at top. Just follow the old sensor wire up and attach the new one as you take off the old one so you properly route it.

 

[Rockhounder]

Did the wire outputs have the stress reducers? (kind of like the perforated diminishing diameter rubber attachments you find on headphone cords above the plug?) We have a Lapidary Society of Los Angeles member who put these on all his flexible lines where they entered hardpoints under the frame, after a flexion breakage. (Toyota Tacoma truck, 4" lift)

If I'm envisioning what you're describing there is a Land Rover part for splicing/replacing the wire that connects the height sensor to the wire harness.
And there are forum threads about rerouting wires if you have slightly oversized tires or go offroad much (articulation can rub the wires).

I don't have links at hand, but I can try to look tomorrow.
