LLAMS electronic height controller for D3/D4/RRS

Enabling recovery mode doesn't do any calibrations so no need to ensure the suspension system is able to level at normal and off-road heights, which can only be done with the engine running and the doors closed. It will enable as long as the battery is connected and the main suspension fuse is fitted, even if the ignition is off. If the Llams module looses its power supply it will revert to standard operation.

Yes, the reference is to the rotary switch. If it transpires that a momentary switch becomes desireable, I might get to include a miniature switch on a short lead (500mm?) to save people having to chase around finding suitable bits. The cost of parts is minimal and a lead wouldn't take long to assemble.

Actually I was thinking that it would be nice if say a length of wire about a meter long was included, (but no switch.)

Ideally the wire would have terminals or whatever to slip over the two pins, (as that would preclude me melting the circuit board). With regard to a momentary switch as everyone would have a different idea of where the hidden momentary switch should be located and what it should look like, and momentary are easy to find near anywhere, (Mundiwindi or Tanami, well maybe not), that the switch need not be included.

sounds like a great solution. Ill get this right there are 5 modes instead of 3. The standard air suspension seems to have disembark mode (low), normal, and off road (high), selectable from the toggle. Will I be able to drive in high mode more than 50km/h?

Hi Gazm3,

The cabin switch has 4 positions, -20mm (high-speed height, not access height), OFF, +30mm & +50mm (nominally off-road height). These height adjustments are when the air suspension system is at normal on-road height but can also be used at access and off-road heights with close to the same height adjustments. When used at normal height, no speed restrictions occur because there are no speed restrictions at normal height, excepting for a sustained 160 kph or more where the vehicle will lower by 20mm.

The new recovery feature, for use when the suspension lowers to around access height ('suspension lowering' or similar message) when some other system fault occurs, is enabled by opening the module box with the Llams switch set at +50 and connecting 2 pins together with a screw-driver (or key etc) or by pressing a momentary switch if one has been installed. This mode changes the height adjustments so that the +30 switch setting gives the usual +50 adjustment and the +50 setting gives double the usual +50 setting. This special mode is provided because when at access height, the usual +50 adjustment only provides on-road height whereas double +50 provides off-road height so that if off-road height is actually needed, it can be obtained. The suspension system will not lower the vehicle at 50 kph in recovery +50 because it thinks the vehicle is still at the proper height, just like it does with any other Llams switch setting.

The recovery +50 when used at normal height is about super-extended height and whilst the suspension will stay raised at that height regardless of speed, it could be dangerous and thus irresponsible to drive at more than just slowly at this height. Its about the same height as normal Llams +50 when in off-road mode and that's limited to 50 kph because of using off-road mode, but even that speed could be too fast in a lot of circumstances. Super-extended height is normally limited to a very slow speed but being able to select that height without grounding the vehicle first is a significant benefit, but it needs to be used responsibly.

Just returned from Moreton after installing the LLams unit and all I can say is that it's brilliant. I was there a fortnight earlier without it and was "bonged to death" so thanks to the clever people who developed this gear - I can whole heartedly recommend it !

Just Like to add my feedback for this product. We have just completed a trip from Dalhousie across the Rig road and from Poepells corner up the Hay River to Jervois. Most of the time in the sand I used the +30mm setting with ocasional changes to +50 in the sandier spots.
The system just works and I did not have any of the damage sustained by the other Disco 3 who bottomed out on several occasions due to the suspension dropping as we got up to 50KM/H . I also was not driven crazy by the constant "bongs" alerting me to slow down or the vehicle would lower.
Excellent product, easy to install and I am happy to recommend it.

Regards,
Tote

Here's a note for the V1.1 modules that support recovery mode.

If a remote mode switch is fitted and it is inadvertantly operated with the Llams height switch OFF (starts a re-calibration), switching to HIGH then operating the mode switch again will cancel the re-calibration process and enable recovery mode. If recovery mode is not required then momentarily switch to LOW to cancel recovery mode.

LLams turned up. Wiring looked easy enough and thanks to Rich for instructions for V1.1 installed and ready to calibrate. :D.
Tried to raise several times with faults stopping the lot. Turned off and restarted repeatedly with only a tiny raise before faults brought me back to normal. :( , battery off and rechecked all connections - all locked and snug, Same result:(

Added loop back to loom to see if it was a loom or control fault and had the same issue. Control box is probebly fine:)

Battery off- loom off and everything exculding my new LLAMS works. I was worried I might have damaged the cars wiring while unplugging to plugging in the new loom in but no issues :D.

I will send loom back to get tested but thankfully my trip next week is not faulty:D. I build a lot of computers and wiring with plugs as big as these is pretty stright forward. Might still be a ME issue though as there is no bent pins in loom make me feel it is not a me issue:D:D:D

Riches great guide missed getting the cover around the radio off I think. it was very easy just gently at the bottom of the cover on either side after page 6 and before page 7. I used a small dowel with the wire taped to it to get the switch wire (shown on page seven) to the very back very quickly after fiddling for a bit.

Weakestlink,
I can swap the loom. There have been some problems with some of the sockets in the grey connector that plugs into the ecu, although I seem to catch most. That connector needs to be fully and evenly pressed home as even slightly back on 1 end can cause problems.

No problem, thanks.

I think you will find in the Switch PDF it shows how to remove the radio trim!
