Hello. I looked at the logs from tom91 for Gen1. I don't understand. How does ID 312 turn 0x20 (locked) into 0x10 (unlock)? What command blocks the knob? If you look at Gen2 ID 02C there are two command 0x00 and 0x40 (D3). But they don't work for Gun1

This is not a simple switch. There is a resistor between the buttons and ground. When the button is pressed, there is no short circuit between ground and start_stop_1 or _2. The tracks from the buttons go inside the board and there is no way to track them

Do you think the voltage on the start/stop button and the handbrake depends on the CAN bus signal or not? I apply 12V to pin 12 (Wake up). And on pins 7, 18 and 11-ground (start/stop) I get 0V. But according to GSMTSM - Pinout.pdf they must be under voltage. The same situation with manual brake, on ...

What message exactly unlocks and locks the knob? And what message does the knob drop down?

Hello. If anyone needs a modified GEN1 code to connect the relay to the module buttons. Also added module highlighting. But I can’t find what data I need to send to the Can bus to block the knob in the P and R positions. And how to track when the ignition is off and the knob is down (I need this to ...

I checked the code Gen1 by tom91 with a modified void setup ().

void setup()
{
Serial.begin(115200);

if (CAN0.begin(MCP_ANY, CAN_500KBPS, MCP_16MHZ) == CAN_OK)
{
Serial.println("CAN Init OK");
}
else
{
Serial.println("CAN Init Failed");
}
CAN0.setMode(MCP_NORMAL);
pinMode(CAN0_INT ...

Now the knob rotates freely. But in the car, it is locked and only when the brake pedal is pressed does the knob unlock. How to implement it? What data needs to be sent to the CAN bus?

I have now checked this code with another GSM and the knob goes up and down, but the unlock does not work

Hi guys. I adapted LRBen's code for Arduino Uno with CAN shield. Now everything works, but there are a few nuances. When I return the knob from the R to P position, the program crashes for a few seconds and then it works again. Sometimes the situation is the same with position S.
Could you look at ...

I give up. I do not understand what is going on. Sometimes the backlight of the module turns on by itself. It may turn off immediately or work for a long time. I only had one successful launch when everything worked. After 3 days, the knob rose once and the Parking LED lit up, but the knob did not ...

Hi.
I connected another NodeMCU with mcp2515 in parallel and read data between Aruino with mcp2515 and the GSM. Attached are 2 logs from different GSM. It seems to me that the Park wire (14 pin for a 22 pin connector or 10 pin for a 12 pin connector) is not working.

Tomorrow I will buy another mcp2515 module and read the data between the first installation and the GSM. I'll post the log here.

YEHAAAAAAA !!!! The second GSM works with Gen1 :D
Knob rotates and LEDs light up

My joy was short lived. It was possible to launch only 2-3 times. 2 days I can not understand the reason for the failure to turn on. Replaced all wires, removed arduino dupont and soldered mcp2515 with arduino ...

YEHAAAAAAA !!!! The second GSM works with Gen1
Knob rotates and LEDs light up But the first doesn't work at all (9X23- 7E453-DA)

I use MCP2515 like this. It has 120 Om builtin resisror and jamper

Sorry. Could you please repeat your questions? I'm completely confused.

I'm going crazy!!! :x Bought a new GSM JLR EH22-7E453-AB. Uploaded Gen2 sketch to Arduino nano. Knob does not leave when sending 's'.
Connection: PC - USB - Arduino Nano - MCP2515 - CAN GSM. Connection GSM:
1 - 12V,
2 - 12V (IGN),
5 - CAN H,
6 - CAN L,
10 -12V,
12 -Ground
What's wrong? Please ...

Sorry. I realized that these libraries are for the board Arduino DUE. Do you have a sketch for Nano?

Code: Select all

#include "variant.h"
#include <due_can.h>

Where can I download these libraries to test your sketch? Thanks

Maybe we should send a static message for IGN-ON emulation before sending a message with ID 0x3F3?

I decided to go the other way. Turned on the CAN bus and began to analyze ID 0x312.
0x312 from selector
Byte
0. 00 at all times
1. 20 when locked, 10 when unlocked
2. 8F in park, 8E in R, 8D in N, 8C in D, 88 in S
3. Cycling depending on gear state.
4. 00 at all times
5. FF at all times
6. 00 at ...

I downloaded the arduino code Gen 1 from here
https://github.com/Tom-evnut/Land-Rover-Gearknob
You are talking about code Gen 1 JLR GSM. Maybe it's 2 different codes?

There are alot of checksums involved so you need to have an active controller doing it. Static messages do not work, this is why I made the Arduino code public.

Unfortunately it takes quite a bit of effort to make things like this work, if you are not comfortable with CAN bus this is not ...

Do you know the program CANHacker 2.00.02?
In this program I send ID code then nothing happens. I can draw 2 conclusions:
1) The GSM does not work.
2) ID codes do not fit it

This data comes to arduino (TX Led is on). How to send data from arduino (RX)?
