Thread: Td5 cruise control operation

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? Stays lit unit the ‘cruse enable’ switch is turned OFF.

Thanks in advance!

Have a look at
www.discovery2.co.uk A bar / Fitting Cruise Control To a Discovery 2 TD5

"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.

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

One word(or phrase) .. 300TDi!

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
