Technical Duato X244 cruise control retrofit- VICTORY!

GREAT SUCCES!

Installed the 4pins brake switch, which was indeed very easy to remove:) LHD

Took a different 12v supply that had a separate fuse (old wires from firetruck equipement that was installed. connected that 12v supply to the blue wire from brake switch and to the yellow cable of Alfa stalk and BOOM.

works like a charm!

In MultiEcuScan I could see the brake switch 2 act as should (opposite of brake light switch 1) and all CC controls comming in.

Small test drive, works like it should. Cancelled by clutch and brake.

:slayer:

only thing left is installing it neatly.
How did you guys connected the wires in D018 connecter? read something about a Delphi GT150 conncecter, but when I google that it is shows a bit different connectors.

Max,

I am pleased that it is now working OK for you.

As regards the connector D018, some have used a separate 4 pole connector. For the moment I have male pins insulated, held in pairs with heatshrink, inserted into the female section of the D018 and held in with small cable ties. Not pretty, but works and keeps my options open. Currently looking at Delphi drawings of the connector, and have the lower dash removed for another attempt.
 
Yes quite happy with it. Still struggling to properly fit the alfa stalk.
And my "problem" with the D018 plug is that I do have airconditioning.

So thinking about just buying a different 6 pin plug, cut off all wires and connect them to the connectors.

Only difficulty is that the red wire from aircon is a lot thicker, guess 4mm, then the very thin cc wires...

Better to leave the middle two wires for aircon in existing connector. This is what others have done.
 
I’m assisting a fellow Ducato owner with his cruise control install. He has a 2.8 JTD from 2006. The cable to his brake light switch is different to mine, in that the colours are different and there is no intermediate connector to facilitate removing the cable for easy splicing with the Yellow stalk cable. We have connected the correct stalk cables to D018 and the Yellow to pins 3&4 of the BLS, but cruise control doesn’t appear to work.

After careful inspection, the colours seem similar to me.

Judging from the insulation crimping in the first photo, it is possible that previous work may have been done here.

I have previously posted the attached modified copy (my record) of eLearn drawing E5060, but will repeat here for convenience.


I030 at upper left is the brakelight switch. I030/4 (blue/green wire) is the 12V supply from fuse F26 (brakelights). I030/2 (red/black wire) is the brakelight connection.

My drawing shows the "proper" connection via D160A from fuse F27. When using the easier bridge at the brakelight switch, the link at D160A/1-6, and the connection from D160A/1 to the Alfa 147 stalk are not required.

As always, your knowledge and insight is much appreciated Communicator. I’m assisting my friend remotely, so I’ll pass on your information and report back.
 
So all connections checked, but still cruise control is not working. Test drive and nothing. Is there anything to check?
 
Yes everything.

You could start with Multiecuscan and check that the inputs are being seen by the ECU. I do not yet have Multiecuscan, so I would choose to check through the wiring with a multimeter.

Does the vehicle have a clutch pedal switch? This may not be essential but worth checking.


How have the connections at the problematical connector D018B been made?

With ignition ON, is 12V from the brakelight switch reaching the Alfa stalk yellow wire?

With ignition and Alfa stalk ON, is 12V output on the Alfa orange wire?

Also check the raise, lower and resume outputs. (See diagram.)

If all OK, perhaps worth checking that both sides of connector D004A are populated at the appropriate ways. (Usually the other way round, some Italians found that the connections were made from the ECU to D004A, but not continued into the cab, or no relevant connections were extended from the ECU.)


Is pin 1 of the brake pedal switch connected to connector D004A/B09? In view of location of D004A, best to do a continuity check on this one.


Connector D004A is hidden under the engine bay fuseboard. Disconnect battery negative before investigating, hence continuity checks only.
 
Communicator, thanks again for your information and advice. As I said before, I'm assisting a friend remotely with this installation. I'm pleased to say he has successfully installed it. I still don't fully understand why, but connecting the Yellow stalk wire to pins 2 & 3 on the BLS made it fully operational. There was no power to the Yellow wire when connected to 3 & 4 of the BLS.

Burstner685,


A SAFETY WARNING.

In view of the confusion over the connections at the brake pedal switch, I must urge that your friend confirms that pressing the brake pedal disengages the cruise control. This should be done at the first opportunity.
 
I'm know it is old post just I wonder did you or how did you fix the issue. I have same problem with my ducato all connectioms are ok 2003 ducato ducato 2.8
Thabk you
 
Hi cemmy074,

Have your changed the brake pedal (light) switch? You need the black and white two contact switch.

Hi thank you for reply. Yes we put 4 pin break light switch and, connect 2 blue (one is, blue with green) connected together.
Actually after I respray and played with gear knob coz I had stiff gear shift and when I put on cruise it worked once. I am thinking probably it is clutch sensor/switch or another break light switch. But open all other ideas. Thank you
 
I always regard bridging the connections on the brake light switch as a fudge, results in the supply being taken from the brake light fuse instead of F27. However it is perhaps easier.
Do not be confused by the pin numbering for the brake light switch. Fiat have used a different numbering scheme to that moulded onto the harness extension socket.
For the commonly used bridge at the switch, you need the yellow supply wire for the Alfa squib to be connected to blue/green (F26) and blue at the switch. This latter connection feeds 12V via the switch in normal position and grey/black wire to the ECU. I know access is tight, but if you can see 12V on the grey/black wire with ignition on, then switch should be OK.

For further tests, see my post #30 in this thread. Also note that you need to be at greater than 40mph for cruise control to engage.

Thank you for all infos.my plug which is in dash slightly different. It has 4 in 2 out coz of that we direct connect the ecu(yes it is messy) and blue and blue green cables connected together which is, behind the break light switch. I am thinking now maybe my clutch sensor is faulty. Reason is when I had stiff gear knob I used some Wd40 for getcrid dust dirt etc and playined gear knob up down left right few times and I start to car for quick drive. And put cruise on light came on and ready to use till turn off the car. I turned off the car come back and no cruise ligjt come on when I put on cruise (yes before, start it shows there) really confused. And we got power for cruise from ignition live. Do you think is it makes any problem. Tnx

I cannot understand as to why you think that your version of connector D018 B is different from that on other vehicles. Your description suggests that you have do not have aircon fitted, as is the case with my vehicle. The connector has 6 poles, with the two centre poles being larger. When aircon is not fitted the socket (ECU side) has four thin wires in 1, 2, 5, & 6, which are the outer two pairs. The centre two poles are vacant. The plug is the opposite, with the outer four poles being vacant. See attsched picture with four coded wires added to poles 1, 2, 5, & 6. The other two wires are for the aircon option.

If I understand correctly, your problem is that the cruise control light came on when ignition is switched on. The ECU self check sequence switches the cruise control ligt on, but it should go out before you start the engine. The cruise control light should then follow the cruise on / off switch on the Alfa stalk (squib). If this is not happening, then you could have made a wrong connection (Check your wiring carefully.) or the squib may be faulty. The other possibility is that the ECU needs several operations of the cruise control to self learn that it has a cruise control fitted. So if all the wiring checks OK, then keep trying a few more times. Also you have to be travelling at over 40mph for the cruise control to engage.

BIG THANK YOU 🙏🙏 for all reply and help Like I said i don't know why my plug is different than others. Anyway when I read all post about and I decide to take 12v power from break switch blue cables. Which one of the auto electrician took the power from ignition and it never worked. After took the power from blue cables(from break switch) and now my cruise light works after start the car. I ll test drive but I think it will work without any issue.
Thank you for all helps..
