Freelander Cruise control help needed please

This site contains affiliate links for which LandyZone may be compensated if you make a purchase.
I found these instructions regarding a Rover that uses the same Cruise Control Interface Unit (SCB100212) part as the Freelander (even badged Land Rover), which apparently is the 'relay' according to RAVE CD.

Additionally people would still need some kind of mountin bracket, and an ECU, an ECU 'enabling' session at the dealer as previously discussed and the factory installed loom or the whole idea is a non starter.

ECU is presumably available from LR dealer as a spare part?

If not then I am guessing the Rover 75 Cruise ECU may work with the Rover 75/Freelander CCIU?
As a wild guess it's possibly this (Part no: A-0678G01E) from Pektron, an ECU manufacturer. Although for a different car (Rover), this diagram may shed some light on what to do?

Hi TD 4x4
Yes you have identified the correct CC ECU for the Auto FL and the Pecktron unit is the same (as far as I was able to find out). The instruction set is for a ROVER car and the use of a separate loom, if you can get it, may be useful to enable the FL? :)
The wiring/connector under the FL airbag is there and only needs the CC switches mounted and plugged in, the wiring down the column may not be, the wiring for the CC ECU should come out under the drivers seat, if not then you will have a significant amount of wiring missing - may be replaceable using the Rover loom you found? :scratching_chin:
Is your's a manual TD4? if so then I don't think CC was ever an option (unless someone knows otherwise?) :scratching_chin:
If it's an auto then there is also wiring required between the CC ECU and the existing Auto Box ECU to make the CC work (probably not there?)
The wiring behind the CC switch blank may look ok but there was no CC power feed on mine (ignored it and rewired to the aftermarket unit)
When all of the 'original' wiring, ECU's, switches etc. is in place you will need "the dealer" to enable the new set-up for CC via the Test Book, unless they co-operate in enabling your modifications then it won't work - "CC was only offered as a factory fit option". :argue:
Keep looking but don't commit too much hard earned until you are sure it will work and you can get it turned on. (all of this is what I found from my searches and may not be all 100% - I went aftermarket in the end) Hope it helps? :5bcheers2:
 
Hi there, thanks for your very detailed response, lots of info!

Yup, mines an Auto so there's still a glimmer of hope I think for Cruise Control.

Interesting you mentioned the wiring for the CC ECU comes out under the drivers seat? I looked the other day with my camera phone, and found these two plugs not connected, and was presuming it was the for the heated seat 'pads' electrical supply.

So it seems a 50/50 chance the plugs are for either. :confused:

I can see why you went afternarket, and good to hear you had the knowledge and skill for a DIY job, well done.

Sorry to disappoint, but the plugs you can see are for the seat heater and the seat belt "undone" sensor. The plug for the CC ECU is a much more substantial piece of kit.
 
Hi TD4 4x4 - Go back to the beginning of this thread and re-read the posts.
Sounds as if you have not got a handle on how the original system works. :suspicious:
Have you read the "How CC works" sections in the Rave, they set out the elements very well and explain how they communicate to make the system work? :scratching_chin:
If you do get any info. re. useable wiring looms or any dealers willing to retrospectivly turn on the CC system please post back. There's quite a few people out there who would like to have CC on their FL. :cool2:
 
Don't know if this helps but:

Freelander 1 Electronic Control Unit Assembly Cruise Control, Diesel Automatic Transmission or V6 Petrol Automatic Transmission. Part number SCB100211, superceded by SCB100212, from chassis number 1A000001 to 5A999999.

So there are 2 different ECU's.
 
Yup thats correct.
The Auto doozle one collects sensor data and runs via the CAN bus, it talks electronically to the engine ECU to perform the cruise function.
The V6 version collects data from the sensors and drives a vacum pump that 'manually' adjusts the throttle linkage to the throttle body via a servo unit to control the engine speed.
Two different systems. :):)
They do however have some components in common.

Hi Tricity Bill,
Those that have had a go so far have had manual transmissions, tho' some with auto's have enquired - but seem to have not progressed or maybe just not reported their progress? :scratching_chin:
Most retrofit systems use the clutch and brake 'switch' signals to prevent engine overspeed when you take control with CC engaged. (e.g. dip the clutch on CC and engine hits red line trying to maintain road speed without a safety over-ride)
Freelander auto's factory built with CC have a CC ECU and extra wiring, the CC ECU interworks with the Auto Box ECU to handle the gear changes to prevent over-revving (perhaps only available in top gears?).
Some thought may be needed in making sure there is an effective engine over speed limiter on a retrofit to an Auto Box Freelander. (the after-market systems have the safety sense wires but do not show you how to set them up for Auto's) :scratching_chin:
You will not have the factory CC ECU and probably not the wiring either.
I have worked out a way to use the 'original switches' via some new wiring to interface with the WAECO aftermarket system - the bit you would need extra is 'how to ensure that when the auto box changes down the CC unit disengages before the engine revs reach the red line?' - is this really a problem with an auto if you just use the brake switch?? :high5:
PM me your email address and I can send you the other files I did for the manual (too big to post here).
Towed the pikey wagon to Cornwall and back in July - CC was great. (28.8mpg top to top fill towing with CC) :D

Hi TD John,
We've not long bought a Freelander TD4ES (04), I realise that's it is a couple of years since you fitted your cruise control, I downloaded your PDFs, am I right in assuming that all I need do is wire up a bit of breadboard with the components you've listed and source athe cruise control stalks, Cruse control switch, and the waeco unit?
Any help or advice gratefully received!
 
I have 2004 TD4 auto to which I am attempting to retro fit CC I have the master switch, I have the set/resume switch, where will I find the ECU? I have looked under the Drivers seat, for one or the wires..but if it's there I can't see it.. any useful info would be great..I'm going to fit the switches and try it in the vain hope that it might just work like it did on my old TD5...keep your fingers crossed
 
Hi Dorset, If you ain't got the CC ECU under the drivers seat it ain't gonna work!
Garry had a go at retrofitting the standard setup on his commercial and it all worked out ok.
He did fit all of the bits and had all of the wiring already there.
He even had the main ECU already programmed to respond to the CC ECU when he fitted it - nice one Garry.
 
Hi TD John
I do have cc ecu SCB100211 but I am having trouble finding out where to fit it, I'm trying to locate the connector which should be under the drivers seat somewhere but as yet no luck..any ideas as to where I sould be looking??
 
you need the ecu for the cruise control fits under the drivers seat and somebody did one a couple of weeks back and described it on here do a serch for it

Where did you get the cruise control ECU from? The connector is under the drivers seat, there is a slit already in the carpet, you just have to poke around it find it.

That's if yours has the wiring loom
 
Found the connector under the carpet then! ;)
Was it tucked up on the side of the tunnel??
Another sucessful retrofit with an already programmed Main ECU.
The numbers are going up - anyone keeping count?? :):):)
 
I found my connector today. If it helps anyone it was nearer to the door than the centre of the car, and it was on a loom that was doubled back and cable tied up. :)
 
Hi
Mine was found nearer the door than the tunnel but was easy to find in the end just a question of routing around a bit.. Gary
