    It seems like my 2011 LR4 didn’t like the cold this week -32 to -45c . Ive never had an issue like this. Suspension is staying in the lowered position. (It says for my safety). The terrain selector, Hd, height control buttons don’t work.
    I was success full in driving into the shop to thaw it out for a few days but nothing has changed these are the messages I need help with.

    Stability control not available Drive with care,

    Hdc not available system fault

    emergency brake assist not available

    And my headlight swivel gauge light is on.

    That is pretty cold. I would expect some non-critical components to misbehave.

    If you don't have an IID tool, I'd probably try a hard reset first, disconnect the battery and touch the positive and negative leads together for 10 seconds or so.

    thanks for the advice, I did plug in a tool and it showed nothing, and i disconnected the battery for a few days and trickle charged it. its just something i do with equipment when i know there sitting for a while. My guess is that a computer is down, there is a lot of things spontaneously not working. I checked all the fuses too they were good.

    Yeah warm it up and hard reset. Likely fine. FWIW I am just south of you and the LR4 has been fine. I guess don't drop the suspension when the arctic air is in town.

    thanks for the reply. although i did warm it up in the heated shop for 5 days now, and nothing has changed. And i didn't lower the suspension and it doesn't have a leak. After the faults showed up the next phrase was worded something like this "suspension was lowered for my safety" I believe there is a sensor/module/computer/relay/ something that isn't responding. I ordered the proper IDD tool to see if I can find out where the fault may be. I don't want to drive 500kms to the nearest dealership either with the suspension dropped. it would be a rough ride.

    Problem Solved! I ordered the iLand diagnostic tool via Atlantic British Ltd. Within an hour i was able to resolve all the issues. I ran a test, found all the issues mentioned above, then ran a steering calibration test after following the simple instructions of turning the vehicle on and off when asked to, it calibrated and erased all the codes and is as good as new.
    Its seemed like it was ok to drive it in the lowered position. No warnings to stop or slow down. Once the calibration was down I hit the "lower suspension arrow" to see if it was completely deflated. the Air suspension lowered another Inch so I concluded that it wasn't completely deflated just lowered.

    The dealership wanted to me tow the vehicle to the dealership which is 500kms away. NO WAY way i wouldn't do that. And the next opening is only in 3 weeks. I learned from talking to the dealership that 60 vehicles had the same issues from the cold snap and were most likely towed to them.
