Retrofitting Cruise Control to HDI/JTD DW10 (1997cc engine)

JohnDragonMan · 2022-06-16 00:26:49

yep, as if retrofitting air conditioning was not enough!

lets kick it up a notch and aim for cruise control.

so i am hoping this is going to be a little "how too" tutorial.

first off, sorry to all of you mechanical XUD and DW8 engine users, i dont think this will work for you. please dont hate me.. us HDI users.

now then

You'll have all the plugs and wiring necessary for this!

you ever wonder what that big old blanking plate was just under the drivers side blower vent? yeah i know right.. i thought it was where a cup holder was meant to go too!
well it turns out its for the switch that "turns on" the cruise control. its a connector with 4 wires. 2x wires are for the switch and 2x wires are for the LED which tells you when its active (i think will update)

any switch and a notification panel indicator would suffice. you can get the original switch but its costly just for a switch (part number Fiat: 1471957699, Citroen/Peugeot: 6552 PQ)

now for the foot brake switch.. easy! just modify a brake light switch from a scrap yard, fit it, and plug it in! you have to file down the little bump on it, then it plugs right on in. you can still buy this if you want but again costly (part number Fiat: 9606177280, Citroen/Peugeot: 4534 26)

now for the column speed switch lever stalk thingy.. oh boy.. this .. you cant get this anywhere. well the odd seller on some European ebay shop may have one but expect three figure numbers! (part number Fiat: 9627551769, Citroen/Peugeot: 6239 g9)
or.. theres my option..
just modify the radio control stalk from a mk1 Peugeot 206cc.. as its THE SAME stalk. seriously. identical. (part number 96373745zl) .. with one exception.. it only has 2 wires. where as the one we need has 5 wires.
now hold on. if i know a thing about vehicle radios.. and i do.. that 206 radio control stalk will have 4 buttons. just like the cruise control stalk. only the 206 being for a radio will be "resistive" meaning each switch makes a different resistance the radio sees.

well we're not interested in the resistors but if i can tap directly into the switches.. hmm 4 buttons.. 1 common wire going to all switches.. and 1 wire coming out of all switches.. equals 5 wires! well that was easy! getting them in the right order will be fun but i can do that by jacking up the front and "driving" the van with the wheels moving in free space to see what each wire/pin on the vans speed control column switch plug does. my guess is on/off speed up/down. i don't have a manual to hand so cant confirm that.

given what we now know.. umm assume.. that should be working cruise control. as far as i know there's no software lock out in the ECU.. why would there be? i mean it was usually an optional extra fitted at the dealership.

so i guess ill report back a little later on. i will naturally edit this post as and when i figure out new info... and add photos. i have a few already but they are not my photos to upload here. i will also be documenting this on Youtube too.

what will the next project be.. heated mirrors? electric windows? front fog lights?? who knows....

I sometimes dream of setting up some kind of arduino-based contraption with a signal from the speedo (it must be possible to decode it) and a small servo that pulls the accelerator cable

It sounds like a fantastic way to get into a crash when it inevitably malfunctions, but I'd love to try it.

Maybe a project for the SORNd 806

JohnDragonMan · 2022-06-18 02:27:26

hmm.. i think its more than doable using an arduino. i sadly know nothing about programming. i wanted to make a random timed random sound generator but meh it was too hard... also a keypad door lock with built in sound but again i dont know how. have all the hardware but just not the skill.

you'd need a good actuator as its pretty heavy.. i mean to make it safe you would just have to put a sense on the brake light switch.. as soon as it sees the brake lights come on, the system would shut down.
i think the DW8 had the option for cruise (it does in the parts catalogue for that engine), i just do not know how it controlls it.

JohnDragonMan · 2022-06-19 18:05:53

Ok my "radio" control stalk came through the post.. yeah i know.. on a sunday?!

sure enough it was 2 wires.. soon managed to pop the 4 clips holding it together off and have a look inside

label from the radio control stalk (note L33t image editing skillz0r):

ohhh whats in heeerrrreeee.....

well as my suspicions were true. resistive!

after a quick study of how it works i plugged the soldering iron in and set to modifying it

note i cut the original track on the left of the last picture. ^

here it all is as a kinda real life exploded diagram:

and the final product:

well its a shame im at work tomorrow but i may have a go at stripping the steering wheel column plastics off on my lunch break.

i have already fitted the extra brake pedal switch (literally did that in the first few weeks of having the van lmao) so all i have to do is fit the "on off" (with notifcation LED) switch and try to make it look good.. no hacked/slashed plastics

well stay tuned. as next time on the "eccentric channel" we may be running cruise...
definitely my most easy project with the van so far..

I think it has a bit of velcro on the underside of the throttle peddle...and another on the floor.

Yep, when I had my DW8 that was a sure fire way to stay at pace with the trucks roll

vaz2121 · 2022-08-21 05:34:18

That looks suspiciously like the radio stalk already fitted to my 306 that I rarely use....................

JohnDragonMan · 2022-08-21 23:28:12

it is! just modified.

so far i have not had any luck with this... i have fitted a latching switch (a rear window heater/de-mister switch) and the little built in indication light turns on but nothing seems to change.
now it says in the vans manual that cruise control only works when it is in 4th gear or higher. so it makes me wonder if it has a way of knowing what gear its in. now ive had all the gearbox out, gear linkages and whole dashboard and didnt find anything that looked like a blank plug for connecting a "what gear am i in" sensor.. hmm

at this point i really need to reverse engineer one already fit to a van i think.

i am 90% sure i have the cruise control stalk wired in correctly.. so i am not sure why its not working..
i need to find another vehicle with the same cruise control i can take a look at.. hmmm

if anyone has any info, please share it with the world big_smile

Led_yob · 2022-09-21 11:45:41

Hi John, I have heard that the cruise control functionality needs to be deliberately switched on in the ECU in order for it to function. This is for the Mk2 however so don't know if it applies to the Mk1 as well.

JohnDragonMan · 2022-09-23 00:14:21

i think it does, i have tried most things but i cant get it to work. shame. ive needed it quite a few times. i still would like to have a look how it is wired into another vehicle. its strange how all the plugs are in the wiring loom but it still does not work so i guess it is that the ECU needs to have a £600 box ticked.

wonder where i can get the software from... i know these only need connection to the OBD for remapping so i would assume its the same for enabling optional extras.

Neill125 · 2022-11-07 22:23:50

Hi New to the forum please be kind.

I have a 2005 fiat scudo jtd
And have also wanted to add cruise control for quite some time.

I spoke to the part's guy at fiat a few years back (very helpful) and went through their details of what was required. But as the prices was so expensive new we both agreed it would be better to source them second hand and left with the list of part numbers.

I looked counless times but couldn't source the parts. But after years of searching I've found the stalk.

The switch however no such luck.
So I suppose the option for that is to make one fit.
I have the connector block under the drivers side blower vent with the 4 wires. But if possible does anyone know the pin layout for it.

Many Thanks

Neil

JohnDragonMan · 2022-11-08 00:33:27

Greetings! welcome to the forum.

i am not sure on the switch pinouts, however its quite easy to work out. one wire is an earth (usually yellow and/or green), one wire is an ignition live, one wire is illumination, and finally one wire goes to the ECU (i think, i am looking for an ECU pin out diagram). using a multi meter you can probe these to find out whats what. the switch is meant to be a momentary switch. the main issue is, i do not know if the switch switches a live to the ECU or an earth. i tried the earth first but nothing seemed to happen, then i switched a live to the ecu pin regulated to 5 milliamps to see if that would "turn on" cruise control (seems strange to have an ignition live in the 4 wires if it does not use it), but again.. nothing (or maybe something i do not know as there seems to be no indication light to tell you that cruse is turned on.

theres also the possibility that the 4 pin plug below the vent does not do cruse control at all! it may be the heated mirror switch! (though i did probe every pin on the door plug to see if i had continuity but nothing besides the earth wire)

i have sadly not tried since my last post to get it all working, i have just been that busy with general life/work.

i dont suppose you could post a picture of your cruse control stalk (where the wires go into the stalk so i can guess where they go internally.. unless you fancy taking a photo of it taken apart so i can see where the wires connect to the PCB also if it has any little resistors inside? angel )
also a photo of the plug showing what pins the wire colours go to.. as again i do not know if i have mine plugged into the correct wires.

its a fun little project and when i do perfect it i will freely and openly give all details on how to do it yourself. as always the hard part is working it all out.

thanks, i hope this helps! please post any results! big_smile

Neill125 · 2022-11-08 22:07:00

Hi Thank you for your quick response.

I'd have replied sooner but a bit more research and then work got in the way.

I'm also starting to think the 4 pin connector might not be the right one and it's actually the one for heated seats. It looks like it's in the right place in my van.

So after more research I've managed to get an image of the required switch and although not brilliant the picture shows more than 4 pins. 5 I think.
I've also managed to source a switch for the heated seats to compare. Just got to wait till it arrives.

Managed to get to the main dealers earlier (Peugeot) and had a good look with the helpful parts guy for any other attachments and couldn't find a thing.

I must confess. I'm not to keen on taking the stalk apart at the moment. I'd much rather prove the thing works first. But I'm more that happy to share my findings any images that may help.

Cheers Neil

Worth a read.
So It could be the right connector.

Hi, JohnDragonMan
How did you connect the switches on the stalk?
Two of them are momentary ON (probable the Increase and Decrease speed) and one is momentary OFF

Following with interest, my left foot has problems keeping the van at a (legal) cruising speed. smile

i cant thank you enough for this info. i cant wait to try this out!

so in the modified radio stalk, it has 4 switches. all of them are momentary on. looks like i will have to take to ebay and find a momentary off switch. failing that, i could use a micro switch.

this is indeed valuable info.

hmm one of the wires has 5V? i will have to check this.

i may make a little test rig of buttons or micro switches.

thanks for this! if ou find anything else, please let the world know!

jonasfrito · 2023-05-20 19:54:15

Hi, the "5V MR" means its a 5 connector plug , colour brown.
According to this
http://www.autoelectric.ru/auto/peugeot … agrams.htm
I'm trying to upload squematics for the cruise control.
I've got them from this post:

https://dispatchexpertscudo.org.uk/foru … hp?id=1516

The software is quite fussy, only was able to make it work on Internet Explorer on a Windows 7

Was this somewhat a cul-de-sac of an endeavour or did either of you get any success?
I didn't realise that our engine versions were electronically controlled CC vs mechanical so never gave it much thought but would love to add this as a quick project if it's dooable and not financially unviable!
I have a lexia (currently misplaced) but last time I hooked it up it showed very basic options vs my same year XPic

jonasfrito · 2023-06-18 16:27:05

@Mixerfistit, i will only have time to mess around with with the van on my summer vacations, soo... hang tight.
If you make any breakthrough do share it with us.
In other subject in the "Lexia" can you see the state of inputs of the ECU? As in if a switch is pressed (eg clutch switch)
And does it show the injector pump input pressure?
I´m having a intermitent "P0230 Fuel Pump Primary Circuit" and i'm on the fence about buying a Lexia (or equivalent )
Thanks.

ive not yet had chance to play any more with the cruse control.. its on my list just no time any more.

Jonasfrito, pleae see a post i made here regarding your fault code :

Thank's JohnDragonMan, that exactly the info i needed.
Just bought a Delphi ds150e in Aliexpress.

My 2004 SX/Dynamic Scudo comes with everything on your wish list plus aircon. Only thing not included is the cruise control.

Can't help thinking you would have saved yourself a lot of grief, aggro and work looking out for a good SX. But where's the challenge in that? smile

Hello, I know it's an old topic but stumbled upon it and wanted to encourage the random googler by saying that this is definitely doable.
I retrofitted CC to my 2001 HDi Jumpy/Dispatch a few (8?) years back. The switch below the vent is not really necessary, I was lazy and shorted the relevant contacts with a piece of a paperclip. You'd never use that switch after toggling it once, anyway. I used the original stalk from a 406, there is nothing fancy inside the stalk, see post #15. I bet you could emulate one with a few switches if need be. You also need the secondary switch for the brake pedal, it should work opposite to the brake light switch (i.e. normally open?). You can use pretty much any switch here with a little imagination, a reed switch and a small magnet on the pedal should work just fine. Don't forget the plastic grommet for the hole of the switch if yout get the original from a donor car. You can, of course, do without the grommet with a couple of zip ties or the like, but it is rather fiddly getting the distance right.

Just be warned, at least on my car (with the single long ECU connector, dunno about the newer three connector ECU) they had played a little prank with the wiring. All the relevant wiring was there inside the cabin, but one of the wires apparently terminated in the loom somewhere. Can't remember which wire, but I think it was present at the ECU end of the loom, too. So I had to run a new wire to meet the one at the ECU. The Peugeot wiring diagram software was invaluable while diagnosing this. PP2000 should tell you whether the ECU sees all relevant switching action, too, but at least I couldn't point out the fault beforehand. As said, you need to enable the CC in the ECU with Lexia. It might be doable with the ds150, too. Or any software you can use to mess with the ECU program code...

Oh, and you can also swap the gearbox from a compatible passenger car (I got one from the same 406 I took the stalk from) if you fancy longer gear ratios. IIRC, you only need to fabricate a new bracket for the gear lever cables, otherwise it is pretty straight-forward. The gear pattern will be upside down and mirrored, but that can be turned around without too much trouble.
