HDC fault SPECIAL PROGRAMS OFF

Report post
I have a yellow break light on I have a yellow triangle with circle antilock brake signal on and I have special program off h d c fault. At first I thought it was going to be a speed sensor. So I bought a front and a rear speed sensor for it but have not put them in yet because I don't know which beach has her to do yet haven't got it pinned down that far. Then I started reading where it could be some corrosion in my fuse box underneath the glove box. I am going to check that first to see if there's any corrosion there because I do have that notorious leak in my sunroof on the passenger side. I don't have the right type of scanner to scan all that although my says it will scan the ABS system for my Land Rover and it's not pulling that code. The only code I'm pulling is one for the y'all reach on the vehicle and that's because I have a red light because I have my air suspension taken out and coil springs put on. I replace the battery about a year ago and checked it on my battery machine I charged it on a battery analyzer I hate does the real real slow call Skype charging but I do that every 6 months religiously with all of my vehicles. So if I get time today I'm going to pull it into the garage and have a look at that fuse box see what I can see I'm pretty sure I'll find some green spots in there. I'll keep you all inform

I forgot to tell you in that post. I took out the air suspension system and put in coil springs. I put in some little computer chip that came with the coils that was supposed to bypass the error or fix the errors in there but I still get the red light and that code from that. I've been working on this HDC fault for a couple of weeks now and I live in a small town and nobody around here has a scanner that can read the Land Rover codes for me. So I'm back to thinking the HDC fault special programs off is a speed sensor gone bad somewhere. Now the fun part just trying to figure out which one. You have to remove the inner fender cover to access speed sensor on the backside. If I can get to them I can test them I just ohm them out and take a voltage reading on them and see which ones not working. If they're all working I'm going to go climb a big tree somewhere

Steering angle sensor needs re calibrating probably. Once you have defeated the idiots any job is half done. Pity there are so many idiots to defeat.

When I bought mine it had the same lights on.

Re calibrating the steering angle sensor fixed it.

Just re calibrated the steering angle sensor. The three amigos were up now gone and car OK.

Yet again the Autel AP 200 did the job. Well worth the £50 . Save me three times that up to date! Once you have defeated the idiots any job is half done. Pity there are so many idiots to defeat.
