after all its the same signal sending to the body computer right?
Pls send me a link or photos of the sensor, I need the sensor S/N or ID.

Re: Rain sensor...

Unfortunately, my body computer doesn't want to enable rain sensor option. When I enable it and then I do the proxy aligment, the body computer reports a fail at some point "Fail-Procedure Out of range, but, on the other hand, the dashboard recognizes the option and it enables on menu the rain sensor sensibility option. Once it has finished the proxy alignment, I go back to the enable/disable options menu on MultiECUScan 3.0 and it keeps disabled (Rain sensor and also I tried with dusk sensor). I also tested with AlfaOBD (PC and Android version) and it says "Fail sub parameter blablablah....".

I don't know if the body computer needs to be a different module or software since it doesn't leave me to, for example, enable "Comfort close/opening" and use the remote to open and close windows. Maybe replacing the body computer might fix that issue, but It will cost a bunch of $$ even if the body computer is from 2nd hand due to we need to reprogram inmo and key decoder, replace the chip from the new body and then use my old chip, or clone info to new chip (2nd and 3rd options are quite dangerous if you do it wrong)

I will keep trying, but for now is not possible. I can also try to use a MCU to emulate the ECU system and turn the windshield washers on

Regards,
Julio.

I think I found the issue, the car body computer knows that my car is a Dynamic Version, and it might be the issue, because my car does not has Rain sensor by default, but the instrument cluster let me do it because is a newer version from another GP Sport or Emotion, wich it includes Rain Sensor. On the other hand, I think I has not sense, because my car, as Wikipedia says: "Dynamic version does not come with Cruise Control or Front Fog lights, but I was able to install them, so I think that my problem come from the OBDII adapter, and I think I will have to buy another more advanced than my Chinese ELM327 WiFi hehehe

If I have time, I will buy a better OBDII adapter and try it again.

Greetings,
Julio.

Re: Rain sensor...

*Pls read the previous message, there is some interesting info*
The sensor that it will work with your car is the Opel/Vauxhall, it is the same as GP hehehe.

I recommend to test the sensor before try to install it on car. It works with 12v power supply. Use a 12v and apply power and then check between +12v and GND goes almost +12v, and between GND and Signal there are some voltage.

Rain sensor's pinout on eLearn is "K085" and electronic diagram and how windshield wipers work are described at "E3020"

Pin 1(RED): +12v goes to Body computer - Connector E - PIN 7
Pin 2(BLACK): GND goes to Chassis GND
Pin 3(GREEN): Signal +12v goes to Body computer - Connector A - PIN 35









Regards,
Julio.

Re: Rain sensor...

Ola Julio,

nice to read from You again ! I'd been interested by the rain sensor saga, and more by the cruise control you seem to have implemented in your GP.

I had wires from stalk connector (pins 8 & 10) derivated to a breadboard so I could simulate the resistors voltage divider that is used to drive the cruise control. So far I could succeed in enabling the CC in the proxy alignement section of MES, but I can't activate it using the 2K4 resistor that is supposed to be in the circuit when CC is switched ON (according to eLearn test procedure). Neither can I turn the light ON using the actuators section :-(

I thought those "options" were part of the "preparation" job done @ the dealer when new car arrives (assuming the HW is present), like the comfort close/opening which doesn't require extra HW; might be only accessible with the official dealer system ??

Let us know what you'll find out with your "decent" ELM327 ;-)

Best regards, Bernie

Re: Rain sensor...

Hi Julio,

Great to see your determination in this project. The best thing is definitely to get a good cable like you are planning(have a look at Alfaodb web page their are links for various cable.

I also encountered an error when I tried to configure ESP to body computer it was also a cable issue, Alexey of Alfaodb was very helpful he even sent me a special version of the software to work around my cheap cable.

Try to contact him and good luck.

Hi julio,

Thanks for the info

My car came with Cruise control and front fog lights. seems like it should work for my car. i ll try to enable the rain sensor menu on my cluster panel with MES first.

Regards

Re: Rain sensor...

Just out of curiosity I removed the lights and found that the rain sensor socket and sun roof socket where hidden inside the liner.

Maybe is because your car is another version than mine. What version is? Emotion? Dynamic? Sport? It is really important. Mine for example, is a Dynamic version late '07 does no comes with that connector sadly

Thank you for that info. When you say "good cable", are you meaning about OBDII adapter? I've also used ethernet wire twisted.

By the way, thanks for your ESP retrofit tutorial

I contacted him a year ago asking about how steering wheel system codes works and he is a really good guy. I will ask him again.

The ESP retrofit tutorial is awesome, is just what I was looking for. I made a PDF translating it to Spanish because reading too much english makes me go crazy hehehe. Maybe next month I will ask you a few question about it, when I'd have all parts required.

Greetings,
Julio.

Hey Bernie,

sorry for the late reply! Too much different messages on same thread

You have to connect pin 8 to 10 that is ground, but you have also connect the 8 wire to pin 41 on Body Computer connector "D". Then you have to enable Cruise Control and do proxy aligment with load resistor emulating "ON" switch on CC, as far as the Body Computer check all its stuff, on your dashboard will appear "Cruise Control Enabled" and the CC icon ON.







Check if your car instrument cluster has the LED inside, otherwise you won't see the logo and some people says that if cluster does not have that light or something like that you wont able to enable it. I tried with old instrument cluster with NO CC LED and it worked alongside with new cluster that has LED on it (that a long stuff messing around with OBD port hehehe).

Maybe rain sensor and auto-close stuff is not working due to using a cheap ELM327.

I think that is time to get a better adapter since I want to go further than CC and read codes. With a Launch adapter you can only read a few stuff and write injectors codes, but nothing else, so I am looking for what OBDII adapter can I buy.

Guys, what do you recommend me to get? OBDLink or OBDKey?

Thanks mates!

Greetings,
Julio.

Re: Rain sensor...

Hola Julio,

thanks for the reply !
I understand that MO1 provides a grounding reference to the CC switch thru its pin 34 to pin 10 of the stalk. This ground is then sent back from pin 8 to the BC's pin 41, AFTER going thru various resistors so the BC knows the status of the CC stalk. 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 ...

Re: Rain sensor...

Hi Julio

Yes I mean the ELM cable. This one seems to have been tested by Alfaodb and not that expensive.

https://www.obdauto.fr/interface-dia...bd-c2x24887519

My car version as reported by using VIN on eper is Emotion but according to my Insurance company it is Dynamic?

Regards

I think that is Emotion, Dynamic is cheaper on insurance than Emotion
Take a picture of your dashboard and show me it, then I will tell you, but if Fiat says Emotion is Emotion.

I have similar OBDII device from china with same chip, and same ELM version, but in my case is WiFi and bluetooth, so I think that problem is or ELM327 does not works well with AlfaOBD or I just can't enable it. I will buy it anyway but I think that the problem is that car doesn't want to enable it :S
