There is a procedure to test the switches in eLearn, but it doesn't make sense with the switch drawing...
Could you by any chance measure the RESISTANCE between pins 8 and 10 of the stalk connector (with plug removed) for the 5 different positions ??

- OFF: circuit open (I guess)
- ON: eLearn says 2480 Ω
- increase/set speed: eLearn says 740 Ω
- decrease: eLearn says 345 Ω
- resume: eLearn says 132 Ω

It is possible to obtain those values, but NOT with the switch wiring as drawn in eLearn !

Muchas gracias, Bernie

edit: do you mean the resistor needs to be connected BEFORE doing CC enabling and proxy alignement ?? That may explain why it's not working on my mjet ...

-Yes

-Yes and maybe, that happened to me, and also was due to bad connection between 8 and 41

Greetings!

Have you done it, or would you do it ? If already done, what were the values please ?

BRs, Bernie

Sure, I have to open the steering wheel, so tomorrow I will do it if I have time (I gotta go work too). If I can't, I will do it next day (Thursday). Promised.

Best regards,
Julio.

Re: Rain sensor...

Holà Julio,

thanks a lot for taking your time to do that measurement. So once again to be as clear as possible, I need to know the actual (true) schematic of the Cruise Control portion of the multi-stalk (H005), since there is a discrepancy in eLearn between the drawing of that switch and the testing procedure: there is NO WAY to measure 2480 Ω when CC is ON with the provided drawing !

The idea behind all this is to build an external command to mimic the (expensive) CC stalk: two switches and a few resistors would be enough, just need to know the correct values on a genuine stalk ...

Thanks, Bernie

Hello Bernie,

First of all, I want to apologize about my huge and unacceptable delay, I was too busy at work with lot of issues, summer is over our heads and it is impossible to work outside without become a big roasted chicken, but after researching my documents I found that I have the values of resistor on CC (tested by me) and values are close to what eLearn says, note that there can be a difference of +/- 20% or so. I can tell you that eLearn says correct values "always" (or at least for me), because I also tried to check values with dash buttons like fog lights and car headlights regulation, and I took a look at eLearn and follow the values it says and it worked (headlights motors moved and fog lights turned on).

I took a look at the drawing and it don't get it, for me it has no sense, maybe it is wrong or I am wrong, not sure, but you only need to get load resistor/s that will match with what eLearn says and connect them between Pin 41 (Positive +) and GND.

Also I recommend to use and diode as I see at eLearn Drawing, for preventing peaks that would damage car's Body Computer (trust me, I know what I am talking about).

For me I had to use MultiECUscan for turning on CC because AlfaOBD did not work for me, but maybe was due to bad connections o bad setup before proceed with proxy aligment. I recommend to make proxy aligment with the "ON resistor".
Thanks Bernievarian thanked for this post

Re: Rain sensor...

Thanks a lot Julio, now that I'am sure eLearn says the same values as you measured on a real stalk I will proceed with the setup of my CC project …
And don't worry about the delay ;-)

Kind regards, Bernie

Re: Rain sensor...

Hi. I have grande Punto. I would like to ask if you have solved the problem with the installation of the rain sensor? Already working properly? Do sensors from opel/vaxhaull work? I have a dynamic version and there was no rain sensor option in MultiEcuScan. It was necessary to change the body computer to the one from 1. 3 Multijet. There is a rain sensor option. But, when I attach the sensor, it is still information that: automatic wipers not available.
How did you solve this problem?

Re: Rain sensor...

Hi 39 & 40,

those options need different things:

- hardware: sensor being installed behind the windscreen
- hardware II: body computer equipped with the corresponding circuit
- software: the BC loaded with the corresponding software (version)
- Alignment: the BC being taught the car got those options (proxy)

If one of the previous is missing, the option won't be available ...

BRs, Bernie

Re: Rain sensor...

Not sure such a feature exists on the Grande Punto...
See description and drawing from eLearn.

Hi Frau, this forum is not just a "ready to cook" solution, you have to make some efforts to get some results !

If you read it thoroughly you'll find the answer to your last question in replies #12 & 20 from our amigo Julio...
