Hello
I hope that everyone is safe and well. I am one day away from purchasing a 2006 LR3 with surprisingly low mileage. The body condition is excellent, minimal wear and tear, and it drove very well. I was hoping to get some advice.

The air suspension has been removed and replaced with coils. The ride quality is quite good, no sagging or buckling, minimal chassis roll. The Terrain response system however is not functional. I understand there is a flash kit I need to find, to get this going, and I'm currently on the hunt for that.

I do have one beginner question. Given the Terrain response system is out (HDC fault message on dash), I am still able to select 4H, 4L and Downhill assist. I see these lights come on the dash when I engage. So, given that Terrain response is out, and I am still able to activate the basic 4x4 features and downhill assist, is this vehicle still able to engage 4wd ?

An answer would be much appreciated. I have a language barrier with the previous owner, and he keeps saying yes. If it does engage 4wd, how limited is its capabilities without the Terrain response? I grew up around old land cruiser, land rover and nissan patrols (1980s-1995s) and they had no electronics, everything was manual, and they worked incredibly well off road (mountains, wet sand etc). Based on my limited knowledge, I am assuming that minus the terrain response, I would still have full off-road capabilities (tho I am not sure the vehicle has a diff locker).

Thank you for your reading my post.

Cheers everyone and be safe.

 

Just jack up a rear wheel and try to drive away. If it does you have 4x4. As long as traction control is working you will pretty much go anywhere a Terrain Respnse vehicle will go. You can test this by jacking up 2 wheels on the same side, front and rear.

 

thank you for that. Appreciate it.

 

You have a high and low and nothing else, they work fine although not as refined as an EAS equipped vehicle. If the vehicle still has all the EAS equipment i'd be tempted to change it back using 2nd hand parts, you will struggle to find a coil module for it.

 

First off, I would walk away from this. That's just me, I wouldn't want a coiler.

Second, the LR3 is permanent 4WD, so technically without Terrain Response, yes, you'd still have 4WD. You still have a 2-speed transfer case....so as long as the center diff locks as intended, you effectively have a system comparable to what you list above (Land Cruisers, Patrols, etc) in terms of drivetrain. What isn't clear to me is how active the center diff is when the Terrain Response is not functional.

Again, I'd just find the right one...

 

I could not do it, I could not close it, there were far too many unknowns which he was unable to answer. Not to mention the electronic parking brake was faulty, and the cruise control was inactive. The CC by itself wasn’t a deal breaker, but I feared it’s inactivity might be tied to other faults that I wouldn’t be able to diagnose myself with basic tools.

very thankful to all of you for coming to my aid and answering these questions. I appreciate you all and wish everyone the best.
