Description

TruckDevil is a framework for interacting with and assessing ECUs that use J1939 for communications on the CANBUS.

Requirements

Hardware:

The recommended CAN transciever to use is the Macchina M2 (Under-the-Dash).

However, python-can is used so hardware devices with any of the supported interfaces, such as SocketCAN, could be used: (CAN Interface Modules).

Additionally, an OBD-II to J1939 deutsch 9 pin adapter or splitter could be utilized, available on Amazon.

Software:

Python 3 is required.

Additional software is required to flash the m2_sketch firmware to the M2, if used (see Installation).

Installation

> git clone https://github.com/LittleBlondeDevil/TruckDevil.git

M2 (if used)

• Follow the first 3 steps included in the M2 Arduino IDE Quick Start guide
  • Install the Arduino Desktop IDE
  • Install the Macchina M2 Board Configuration
  • Install drivers
• Download and include due_can and can_common libraries from collin80 into IDE
  • due_can
  • can_common

  Sketch > Include Library > Add .Zip Library...
  

• Upload m2_sketch.ino to the M2
  • Ensure M2 is plugged in over USB and that it's selected as the active board.

  Tools > Board: "[...]" > Arduino Due (Native USB Port)
  

  • Select the serial port in use for the M2 (usually named "Arduino Due").

  Tools > Port
  

  • Open the m2_sketch.ino file and upload it to the M2.

  Sketch > Upload
  

  • Once uploaded, disconnect M2 and plug back in.

Usage

TruckDevil contains various modules for reading, sending, ECU discovery, and fuzzing. Additional modules can be added for more specific tasks.

        Provide a setting name and a value to set the setting. For a list of
        available settings and their current and default values see the
        settings command.

        example:
        set read_time 10
        set filter_src_addr 11,249

(truckdevil.read_messages) set num_messages 5

Custom Modules

Create custom modules by creating a python file in the 'modules' folder. The file should contain the following function:

def main_mod(argv, device)

• <b>argv</b> contains the list of arguments passed to the module
• <b>device</b> contains the Device object passed to the module

J1939 API

Python docs are available in the j1939.py file. Existing modules provide example usage.
