Hello all I am in need of some assistance. My 2007 Land Rover Lr3 has started acting up recently.
It shut itself off while driving and also won’t let me start it on separate occasions.
The second time It happened to me I was able to get a video of it. I cycled it a few times and then it finally started.

When It won’t let me start it it says tire pressure monitor system fault followed by hdc system fault system not available and lights all the flasher up and won’t turn over.

The tpms tire symbol has been coming on and staying for a while since I’ve gotten it so I recently added air to all of the tires which were all a few psi lower than it likes I think I may have a small leak in the tires. But this is the first time this has happened.
The other time it shut itself off completely while I was driving it with the same message about the tpms system but this time it out the e break on as well.

Any ideas?
Here is a Link to a video I took of it not starting and the error message.
thanks guys

hello,

as always make sure the battery voltage is correct and i've seen the brake light switch and brake light circuit causing all kinds havoc.
Search brake light switch and see if any of that looks familiar.

best of luck
