I present to you a DIY diagnostic tool for older Chrysler/Dodge/Jeep passenger vehicles and other vehicles that use Chrysler's proprietary CCD-bus and/or SCI-bus to communicate with the outside world.
The scanner can be directly connected to an OBD2 female connector, however using adapter cables it works with OBD1 vehicles too.
At its heart the scanner is a custom Arduino Mega board with circuits to interface with said buses. It's fully compatible and programmable with Arduino IDE via FTDI, AVR ISP programmer (ISP-10 connector) or a simple USB connection. Unfortunately the FTDI auto-reset circuit in V1.41 and V1.42 doesn't work when a CP2102 is present on the PCB. It shares the CP2102's functioning auto-reset circuit and it interferes. Pushing the reset button at the right time however enables programming. Nevertheless I recommend USB-programming, it's the easiest way.
Use the GUI to interface with the scanner and thus your vehicle. You can listen passively to all communications between modules or send request messages. You are welcome to write your own software too.
Check the pictures to decide which one you might need.
V1.41: - USB connector replaced with through-hole variant, - FTDI-connector added (J7); CP2102 is hard to solder, FTDI programming is a good alternative, - C2 and C3 capacitors replaced with SMD-variant, - components moved around and routing changed to optimize layout.
V1.42 (active version): - J6 (EXT_5V) connector replaced and moved, - J7 (FTDI) connector replaced and moved.
V1.43 (future version): - FTDI/USB (CP2102) programming auto-reset circuit is selectable by the new J8 jumper (added C22 for FTDI auto-reset); only one can active at a time, defaults to USB (CP2102) auto-reset, - added D8 and D9 zener diodes for additional CCD-bus protection against voltage transients.
I'm also offering pre-V1.40 bare PCBs for prototyping. They might have issues which I don't remember anymore so I can't take responsibility for whether they will work for you or not. Check the schematics for each version in my blogpost here.
