Hi there,

I'm in the process of installing cruise control system in my 2001 TDDi.

Firstly, I checked the plug on the steering wheel, behind the airbag. There was a full row of pins. My car only used (I believe) 2, for the horn. I bought an airbag with the buttons for the cruise control. Fitted it. Then the horn wasn't working. I played around with FORScan, activated cruise control and the icon in the instrument cluster, and now the horn is working. :driving:

 

Next, pedals sensors. I bought the green and 4-pin red sensor. Unfortunatelly my wiring loom is not ready for cruise control. I need a CC wiring loom, but since I can't find one to buy (I'm from Poland), I must make one myself. I found a couple of schematics, but either for a petrol engine or a facelifted diesel. Apparently facelifted diesels don't have a connector near the gas pedal. Therefore I have no idea how to make a new wiring loom for the sensors.  :tonofbricks:

 

Here's how my stock loom looks. (I already added the green sensor, and 2 wires for the red one, according to one of the schematics)

Here's how the main plug looks like:

Pins 3, 6 and 7 are free. I've heard that some versions (probably facelifted) have pins 1, 2 and 13 free.

I have two new wires, one from the green sensor, and one from the 4-pin red sensor. Where do I connect them?

 

BTW if someone wants to do the same for their prefacelift - I'm not sure if you can activate CC in FORScan. I have a facelifted GEM (generic electronic module) and an added CAN wiring because I was installing a Denso headunit. I don't now if GEM has anything to do with cruise control, but I thought it's worth mentioning.

I dont think anyone ever got the cruise control working on a diesel that didn't already come with

it from the factory.

 

People even swapped out the Gem's and even the ECU's etc and still nothing.

 

 

 

I think you maybe onto a loser here. Sorry..   Although willing to be proven wrong   :)

Check back through some threads to see what has been tried before.

 

Use google

Petrol cars its fairly easy but not so with the diesels, maybe the TDDI is an exception?

Looks like everything can be done  :biggrin: Found a diagram on one of polish forums. It's for a pre-facelift TDCi. I translated it and coloured some of the plugs for easier reading.

Haven't tested it yet. I'll report back when I mount everything and see if it works.

 

Also, in my first post, the second image is wrong. That's a C36 plug, NOT a C32!

 

Cheers!

A little update.

This is the black plug behind the airbag, called C413:

This is the C32 plug, near the fuse box:

I'm pretty sure the diagram is correct. I've checked some of the pins using my old russian multimeter. Weirdly, it turned out that my car already has a connection between the C32 and C413. As you can see here:

I've installed new pedals sensors with the new wiring loom. Fished it nicely through the center console, behind the radio, and above passenger footwell.

Now I have to connect these new wires to the ECU (or PCM module).

 

Luckly the PCM module has every single pin, so it doesn't have to be changed. However its' plug doesn't have holes for these new wires (I guess for waterproofness) but it won't be a problem. I'll just drill some new holes and it should all fit like a glove.

Amazing the stuff coming from Polish, Romanian and Russian forums.

 

Bit like the old school computer scene, amazing stuff coming out for Commodore

C64 machines long after they ceased production.

Still messing with the cruise control. There's one weird thing I can't wrap my head around. Look at my picture where I check the pins with a multimeter.

My car has a connection betweet pins 5/C413 and 7/C32 (pink line on the diagram).

It also has 12V on pin 7/C413 when engine is running.

I thought I checked the connection between pin 6/C413 and 13/C32 (brown line on the diagram). But keep in mind that on this diagram, plug C413 is upside down.

What I actually checked was pin 4/C413 and 13/C32. And there is a connection...

Not quite sure what to do now. I'll check pin 6/C413 and see if it is connected to anything and then I'll report back

 

From 2008

"Well on C413 (clockspring 9 pin plug) pins 3 and 4 are for the horn, pins 1,2, 8 and 9 are to the airbag, and pins 5, 6 and 7 are cruise. Pin 3 is a ground and pin 7 looks like a 7.5A ignition feed for the cruise ao they may be the wires to tap into"

Have you had a search for the old threads where people tried and failed to add

cruise to the diesel?

 

Seem to remember them swapping virtually everything. Pedal switches looms and

even the ECU at one point and nobody reported getting it working.

 

Have a read and see if you think they missed something. Maybe you did something

they didn't and maybe they have done something you have not?
