Td5 cruise control operation

[Aussie_Oz_Born]

G'day,

Can someone please let me know how the Disco TD5 cruise control switches operate? More specifically, is the 'cruise enable' button on the console a momentary button?
The reason I ask is that I have recently acquired a newer ECU for my Defender and I intend on wiring in some switches to enable cruise control. My plan is to have single momentary SPDT switch for the RES and SET functions and a separate switch for the cruise On/Off switch. I was thinking of having an LED mounted to indicate whether the cruise is enabled or not.
So back to the point, does the Disco 'cruise enabled' lamp extinguish when the brake or clutch is depressed, or does it stay lit until the 'cruise enable' switch is turned OFF?

Thanks in advance!

Thanks in advance!

Have a look at
www.discovery2.co.uk A bar / Fitting Cruise Control To a Discovery 2 TD5 (http://www.discovery2.co.uk/cruise_install.html)

"ALL discovery 2 TD5's are "cruise" ready, it just needs "hooking up!!!.......Read On!!!"

I have the drawing here.. I’ll dig it up.

You don’t need a “cruise enable” switch (modern LRs don’t have it) just 2 switches for set and cancel.

Funnily enough they will only inch "up" not "down".

if you want to go slower you have to touch the brakes and reset.

Yeah, a bit of annoyance when I drive brother's D2.
Although an alternative to braking, is to switch it off .. and then on again quickly.

On the rare occasions that I have used the cruise control on my D2a I have started at a lower speed and have inched up to where I want it.
As I like to travel at a maximum of 2-3k's under the posted limit this seems to work for me because if you set the CC to the maximum posted limit you will be speeding on the downhill runs.

[AK83]

I generally set it to a bit less than that again.

One word(or phrase) .. 300TDi! [bigrolf]

No such chance of that happening with a 300 Tdi on cruise .. it seems to slow down even more on the down, than it does on the up

Thanks for the replies everyone, just need to sort out where the buttons will go now. Cheers.

Either methods...

Use a D2 cruise switch and bolt to RHS of wheel

Or push buttons. Top of each side of binnacle.

I'd get the Land Rover parts and install so it looks like it has always been there.

You could also relocate the fuel cap release if needed.

There are no factory parts for a Def.
either way looks factory fit

The OP is talking about a Disco td5, not a Defender.

Way I read it was that the OP was talking about a Defender that he wants to install cruise control to.

I did this to my defender, a crude cruise control but better than none and as good as it could be. Used a momentary rocker switch only, no cruise on/off switch needed.

Ah my bad.

Thanks in advance!The cruise enable switch is not momentary in my 2000 d2 td5. Push it and it stays in, lamp on. Push again and it pops out, lamp off.

One, the cruise control master switch stays on even after ignition key is removed. i.e. Next time you start up it is still "ready to go" until you switch it off. Unlike fog lights.

Two, if overtaking eg on a motorway, you can accelerate with the pedal, and, as long as the whole operation takes less than 30 seconds, take your foot off the pedal and it will go back to the previously set cruise speed.

Three, if you have set cruise for a certain speed and you brake and drive around a bit,using the pedals, eg passing through a town,take feet off pedals then click and hold the reset switch momentarily and it will speed up to the previously set cruise speed.

Four, accelerating using the top button uses a load of fuel, better to use the accelerator pedal gently then the top button to set the new speed. so if you want to do "two", accelerate gently to a bit below previous cruise speed then use reset to get back to where you were previously.

Five, going up hills on cruise uses fuel uselessly, use pedals to be more reasonable then see "three".

How do I know? I drive my D2 constantly in France where there are speed traps and cops with the funny binoculars everywhere. Cruise saves me getting caught out and fined, it also saves fuel provided you are in flatish country.
