L322 TDV6 2003 In active suspension, random "Entry" mode when parked.

[maxperformance]

I was talking with one owner of an L322 TDV6 2003, and they said their L322 has the famous "inactive suspension" since the day they had it. The car always stays at the normal height and will not either go down or up with buttons. However, randomly the car will lower the front (what they claimed "Entry" mode) when it is parked and will come back to the normal height soon as it gets driven.


Any ideas are welcome to help me understand this. What would be the cause, and what would be the solutions?

"Entry mode" will lower the whole car not just front so I'm thinking maybe a leak in the system. Although sometime the front on mine will lower an inch when I'm parked nose down on my steep driveway, and as soon as it starts the front will pop up to normal height.

As far as the Inactive fault goes, low voltage will set that off but you are going to have to scan for faults. Does the inactive message go away even for a bit when you turn the wheel from lock to lock with the car running?

Id probably do this:

1. Check batt condition, low battery health can cause all sorts of fun times. Dont let it drop below 12v. Take it out and give it a charge using a quality charger + test. Supercheap Auto do this for free.
2. Immediately after start, turn wheels lock to lock to reset/calibrate the steering angle sensor <-- common issue
3. Scan tool - LR specific, any module on the canbus that is presenting an error can cause a series of failures for other modules, suspension is generally the one that cops the most heat there

3a. If no Scan tool, just reset everything using the secret menu:

Ignition key must be “off”.
* Press and hold the Check Control button in the instrument cluster (RIGHT button), and turn the ignition key to the first position (KLR).
* You will first see "Check Control OK", some seconds later you will see "Test Nr.01"
* Push the left button on the instrument cluster to see the car's identification number. Add the 5 digits (not 6) together and write down that number, you will need it for unlocking all the functions. Example: A123457 will lead to 2+3+4+5+7 = 21
* Push the right button until you see "Test Nr.19"
* Push left button until you see the number that is equal to the one you calculated above
* Push right button again
* Using the left button select 21. Reset all defect codes
* Press the Right button to select.

4. Park on level ground, disconnect battery completely and leave overnight. This will reset a bunch of modules and you'll be able to see if the suspension has a leak somewhere.

Post back with the Scan Tool results if you have some and we can go from there.

Thanks for putting your thoughtful ideas in.

In fact, I am looking to buy that car. All details I had was from the owner via phone.

However, there is a bit of good long trip to do inspection by myself with my (good enough) MAXICOM scanner, that's why I have to ask you here first before thinking of putting my one day off for the trip.

It sounds like this issue is a common bonus from L322 [bigsmile] (I did inspect another L322 HSE another day and it had the same Inactive suspension issue, and it took age to go up high).

It may need a refurb kit put through it.

Check out 4x4airseals.com.

Thats who I got my refurb kit 4 odd years ago and still working fine.

Another point that it doesnt work is that previous owner probably never used it,so use it often,
even if only driving in/out of your garage. The same goes with low/high range if you dont go 4x4ing.

Hope this helps.

cheers

Only way to know is to read the fault codes. If it says Inactive Suspension there will be a(or more) fault logged - the computer thinks there is an issue and it will have recorded and therefore tell you what it thinks.

I owned a 2004 td6 for 11 years and I had the Inactive Suspension msg a couple times.

when you work on it, like changing an air spring. The fault will be height sensor out of range or similar.
randomly - this happened twice, and the fault logged was "error communicating with CAN bus". clear fault and off it went for another couple years.


This second instance is absurd, essentially, the BUS has dropped a packet and goes into lock down requiring a fault clear. Dropped packets is not something completely unexpected in a car and the software developers should have handled it better, like check if it has connectivity now, log a fault but don't go into lock down. It treats a single lost pack like full connectivity loss.

In short, read the codes - only way to know why it's inactive.

Thanks all. I wish I could be there easily to scan the car myself and do full inspection, but it would take me a whole day to get there and back.
