HDC fault help

I posted this on another forum. No responses yet.


I left my Land Rover LR3 sit for about 11 months. I put a new battery in and started it. I have a bunch of lights on the dash. Here are the codes-
P173C-00(2F)
P0808-00(2F)
P173A-00(2F)
P0900-00(2F)

I cleared them with my gap IID tool tuned the vehivle off then turned it back on. The car returned to normal height. I drove it around for a few miles and it seemed fine. I went to start it up today and the lights were all back on the dash. The codes above are what came up on the scan tool. I tried clearing them but it wont return to normal like it did last time. Any help would greatly be appreciated.

It’s a 2008 LR3 86k. Passenger side floor was wet.

Thanks in advance!

My HDC faults were caused by a weak battery, I would suggest charging your battery clearing the codes and see what comes back

I did put a new battery in before starting it. I feel like something used to drain the battery unless it was just a bad one.

Do you think it needs charged even though it was a new battery?

Yes, new batteries can lie for a while and lose their sparkle, give it a charge whats there to lose?

So I charged the battery up (it was around 67%). And cleared the codes. The lights didn’t go off the dash. Turned it off and turned it back on. Still the same thing.

Did a vehicle reset with my gap IID. The lights went off. I drove it a few miles then let it idle in my driveway for about 25 min. Went back out and all lights are on the dash again.

Any ideas where else to look? I don’t think it’s the alternator bc when the vehicle is running it shows 14.3V on my IID tool.
