yes I connected to my car to check and at the output of the power supply I have 5V and the 12V input

[david51]

Is my connection correct?

I can't test my voltage right now.. I don't remember if I experienced a voltage drop as well... is it giving you some issues?

yes when I press the remote control 3 times, nothing happens.

for connection to the start / stop you just have to transplant yourself on it no need to cut the wires?

Yeah the connections are ok. Are you sure that the 3 lock is detected? And it starts the renote start procedure?

I disassembled everything and put it back as original my remote control no longer works
thanks for help

I don't think I understood what you said

I removed everything from the remote start system. I put everything back as it was originally

FEM Pinouts are all the same, you don't need to worry about that.

I need your help!
In your pictures of the electrical diagram and final look picture can you explain what is the correct connections to the relays?
In electrical diagram all the connections from the relays marked (see picture) as 1, 2 and 3 the connection to the resistance is on the exit marked as "B". On the picture of the final look (your final assembly) the relay number "2" the exit "A" is the on that goes to the resistance. What is the correct one? Diagram or final assembly picture?

Other point, I added the code to Arduino and when I send to the board the arduino starts making the compilation of the code but gives an error not allowing to send to the electric bord. Can you explain what to do? I'm a beginner on Arduino software
.

I really want to complete this project.

ARDUINO ERROR:

Hi!

About the wiring, both pictures has same wiring (but it's not clear in the second picture)

Regarding the code error, you have to add this library: https://github.com/autowp/arduino-mcp2515

You can find out how to do it on the web!

[david51]

it seems to me that in arduino you have to go to option to tell it what type of card you have

How did you made the connections on the FEM module in the car? Did you made an wiring harness to connect directly on the FEM plug or made the connection on the pin on the FEM plug?

I hooked to the wires (scraping off the rubber and exposing it), then secured those connections with some electrical tape.

you can take the power supply and ground directly behind the ventilation on the left side, there is a hidden socket that is useless.

Thanks for the information. Is this connection always powered on? Did you used this one to supply your board?
I can't see in the picture what is the rigth connection. Can you provide addition information so I can undurstad wath is the rigth wires.

Thanks in advance.

If it's the 12V socket then it's not powered all the time. So it's not suitable for this project. This project requires to be always on to catch CAN messages in time.

You have to use the FEM wire I indicated as it's always on.

I took the wrong picture

here is the power supply of the card still on and the mass behind the ventilation.

red the power supply
brown ground

I tested and it is good continuously and not after contact

Nice project,
what is the standby power consumption for this setup?

[AlbertoSONIC]

Hi, should be about 30mA.

Arduino Nano itself operates with 17mA and other components are really low power consuming (fo example, MCP2515 uses 5mA).

Hello, does anyone managed to remote start a car?

I plan to put the electric board just above the obd plug. A connection near that place it would be easy to connect.

First things that come to my mind are idrive or idrive wheel
