That I don't know... since it's serial communication that might make it difficult but I'm just guessing at this point.
Perhaps redirecting using socat?
Anyway, stuff is scanning so I'll have to schedule some time to put into this

I just came across the "panda" device looks like I might get one of those just to tinker with who knows I might be able to add Adaptive Cruise Control to my 14 charger too. https://medium.com/@comma_ai/a-panda-an ... e46fae8646

hmmm my fan speed up isn't the same as your poop ...
The PID I get from cansniffer is 3CE for starters.

interesting ...
Well I fried my CANtact stuck in DFU mode and no way to reflash the firmware on it. So I'm out until I can a new one or an alternate device.
Trying to avoid using an Arduino breakout board, but may not have a choice.

So which pin on the ODB2 connected is CAN h/l if I was connected to HIS? 6 & 14 are usually high/low

Oh well. live and learn

Look up the canable device. There instructions on it for it and cantact firmware update.

Pins 3 & 11 are CAN IHS through the OBDII port.

I havnt tried the CANtact but here's a bit of info
Updating Firmware

"BOOT" pins connected
The CANtact can be updated over USB. First, you will need to put the device into DFU mode by following these steps:
Disconnect the USB cable from the CANtact
Connect the two "BOOT" pins (see image on right)
While the pins are connected, plug the USB cable into the CANtact
The CANtact device is now in DFU mode
The next steps depend on what OS you are using.
Windows
Install the ST DfuSe Tool
Open the DfuSe tool
Click "Choose..." and select a DFU firmware file
Check the "Verify after download" box
Click Upgrade
Wait for the "Verify successful !" message at the bottom of the window.
Linux & OS X
This is possible with dfu-util, guide TODO
Once this is complete, unplug the USB cable, disconnect the "BOOT" pins, and reconnect the USB cable. The device is now updated!

I've managed to make my own GUI for a lot of the canubus ID's that I have. I think I can replace my 4.3" screen in my 14 charger with one of my own. I'm looking around for a touch screen thats similar to the 8.4" uconeect screen. I do have the 8.4" screen but don't have the radio part (some reason doesn't turn on anymore) I'm wondering if there would be a way to just use the screen.

Message id 3e0.

There will be three unique messages. The first byte is the part (00|01|02). The next 7 bytes will be the VIN parts.

Here's (most of) mine:
3E0 00 31 43 36 52 52 37 4B
3E0 01 4D 30 ?? ?? ?? ?? ??
3E0 02 ?? ?? ?? 00 00 00 00

If you're using cansniffer and filter out just that messageID, you should see what I'm talking about.
OK, found it on the 2013 Challenger (low speed bus, 83.3k). Same format, but message ID 0x001B. Follows same format as the 2014, and repeats it every 300ms.

FYI for the 2007 era Charger (low speed bus, 83.3k) the VIN message is in the same format and in message ID 0x01B...
I have a lot of the messages decoded for that model... mostly to replace the Head Unit.... I wonder if the 2013 Challenger has the same messages....

It seems to, so far. I used other know messages that worked on the REC and RER units to this 2013 RHR unit, and it works. I have some data dumps from the 13 Challenger that I have not gone fully through, but do you have the PRNDL messages, and perhaps parking brake and speed for the 07?

Other messages, such as ignition, lights, dimmer, etc, all work the same on the 13. It would appear that the later low speed radio would work in an earlier low speed bus car without issue. I have built a standalone Arduino that will hopefully translate earlier (pre-CAN) J1850 bus to CAN, so that I cna run this RHR radio in my older car :) So far, the CAN side works fine, and I am making a lot of progress on the J1850 side.
