Thread: New D2 TD5 Member to go with TDi300

BUT will the CDL as on my D1 show a light on the dashboard as to when the CDL is both on and or has binding present. If not is it possible to retrofit or even just fit an LED on the console? This the video didn't show

Yes a light will show in the top left as long as you connect the switch on top of the nose to a wire that goes to the BCU.
The wire will terminate in a connector just underneath the switch block for the power windows at the back of the console. I think it is blue with a green tracer, however you should look at a wiring diagram which is in RAVE.

I have put a switch in my wire to enable or disable TC.

You still have to enable TC by lets see if I remember putting the car into diff lock then starting.

I am sure someone will come along and correct me if I am wrong.

Just a later thought. the cars earlier than 2002 may have the switch connected. Mine is a 2002 which had no internals for diff lock.

Thanks for the link Pedro, it certainly has the D2 information as regards to the wheels and accessories, it seems it is English spec as the SAT NAV is for GB and there are no real bull bars!!! My brain loves this stuff.

Thanks also PhillipA, does your install show the CDL is binding or just location of the "switch" on or off - it sure seems the 2000 with the CDL actually fitted will have a light at least if yours doesn't.

Found this on the web

www.discovery2.co.uk/Factory Diff Lock

It would appear from the pictures from 16 on shows the electrical connection for the CDL light and it has a wonderful explanation and solution to the CDL / TC ABS HD functionality with a slicing of the wire from the SLABS

Thinking when I do this, will take the advice of bullet connections but then actually fit a switch to enable /disable and probably mount it near the diagram on the centre console

The switch sits on the selector shaft and rises up a ramp as the diff lock is selected.
The selector shaft/shift fork is spring loaded so it doesn't mean that the lock is actually engaged until the dogs clunk in under the pressure of the spring.
So you may have to zig zag a few times until it drops in but usually it is pretty quick.
Is that what you meant?

Another option and if you have a nanocom to reprogram is get an updated slabs ecu from a later D2a as they are programmed to have the CDL etc and from what I’ve read have a slightly different traction control ABS program...
I did this with my 2002 D2, plug and play with a few simple config changes with the nanocom
Just another option??

Phillip A, so the switch is operated not synchronized with mechanically turning of the CDL on or off, but rather, by the spring loaded dogs which until unbound will keep the CDL light on the dash.

the nanocom is not just diagnostic then, would assume this download would only be from authorized LR dealer so much cheaper to get the updated D2A version but suppose then you still have to nanocom it to recognize the new SLAB, all roads lead back to LR it seems

The software (hardware) update from D2 to D2A has there been a comparison of the two, written or video, over the same terrain as to show any improvement that may be available with the update, this could certainly be a viable upgrade especially as I am putting the CDL lever in, no doubt the software was rewritten to include the advantage of this aspect

My understanding is that the TC action was made less aggressive in the D2A to make it smoother as the TC did not have to work to equalize the 2 axle's rotation.
So I think that the only advantage of the D2A SLABS is that you don't have to follow the start sequence.
Anyway, good luck in finding one!

The Nanocom is good for reprogramming the main ECU etc if you buy a .tune file from an the likes of TD5inside, Storm Tuning, BAS, Alive to name a few! It also lets you change settings for other systems on the ECU, just like a "LR" test book that a dealer would have and you don't need to download any authorised LR programs
It'll also do the SLABS reprogramming for the SLS and other system changes plus the BCU, program keys and more..... Have a read on here for what it'll do Welcome - NANOCOM Diagnostics they are really very handy!
