# VWGC-CanBus
VolksWagen Grand California Can Bus control
For all VW Grand California 600 and 680 owners, this project will help you understand how the Leisure compartment CanBus works, which is independent (or almost) from the Crafter's one.
In this exercise I mapped the activation codes of the various devices: buttons, lights, control panel, etc.
I also created a portable version (smartphone or tablet) of the Dometic control panel that the van is equipped with.
------------------------------------------------------------------------------------
**Hardware:**
I used a Raspberry PI 3B plus but the same thing can easily be done with a Raspberry PI Zero 2 W, smaller, more comfortable and more economical in power consumption.
The CAN-BUS plug-in board used for this project is a: "Waveshare RS485 CAN HAT for Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B, integrated CAN controller: MCP2515, 485 transceiver: SP3485", purchased on AliExpress.
------------------------------------------------------------------------------------
**Software:**
in addition to the basic "can-utils" module easily installable using the "**SUDO APT INSTALL**" command, I developed the graphical interface using Node-RED, convenient, practical, fast.
The Flow used for this dashboard is: "node-red-contrib-socketcan", installable simply from console using the command:
https://flows.nodered.org/node/node-red-contrib-socketcan
**npm install node-red-contrib-socketcan**
------------------------------------------------------------------------------------
**Software Installation:**
After having mounted the CAN HAT plug-in card on your Raspberry, you need to proceed as follows:
**sudo apt install can-utils**
**sudo ip link set can0 down**
**sudo ip link set can0 up type can bitrate 500000 loopback off listen-only off**
**sudo nano /etc/network/interfaces**
modifying as follows:
------------------------------------------------------------------------------------
To be able to "sniff" the data coming from the CAN-BUS it is sufficient to use the command:
**cansniffer can0 -c -t0**
To send a command to a specific device, you must use the command:
**cansend can0 18EF70C9#00.40.00.00.00.00.00.00** (Example)
The list of commands for reading and/or writing is shown in the attached PDF table

------------------------------------------------------------------------------------
To import the Flow Node-RED that generates the dashboard that can then be used via a browser, you need to import the attached Json Flow.

------------------------------------------------------------------------------------
**Leisure CAN-Bus Connections:**
As you can see from the original wiring diagram of the manufacturer below, there are several points where you can connect to the "Convenience CAN-Bus" or Leisure CAN-Bus.
I found it more convenient to connect to the R/G/B controller of the LED strip called: "7C4 947 022" more precisely to pins 9 and 10, as reported by the manufacturer's nomenclature.
The RGB controller is obviously located inside the technical cabinet exactly under the 230V electrical panel
------------------------------------------------------------------------------------
Anyone who can bravely implement other commands for other functions, which I have not been able to intercept or replicate in this exercise, please share them with me and all other VW Grand California users; I'll be very happy.
