Several different angles on the project over the last weeek.
P38a: I am continuing to work on the key and seed encryption protocol that exists on almost all of the vehicle computer subsystems. The protocol appears to be a relatively simple XOR encryption or perhaps some sort of straight forward bit shift. I have absolutely no experience with key and seed methods. So it is a huge learning curve. I am hoping that because of the age of the equipment, circa 1996, that the security seed and key method is very simple.
Discovery 2: I am working on adding all of the different programatic control of the ABS modulator solenoid valves. The methods will allow the user to control the valves for bleeding procedures and testing procedures.
L322 Range Rover: I have been able to complete the Air Suspension calibration procedure from start to finish on my vehicle. The procedure still has some little unknowns that have to be worked out before end users can begin playing with the module. But I now have a vehicle that is 2 inches higher than standard. I also added the ability to enter and exit into Air Suspension Transport mode.
In general I have also added the ability for vehicle settings to be stored in a default configuration file for long term record keeping purposes. This also keeps a record of all the cahnges that have been performed on a vehicle and helps undo accidental changes and settings that may have been lost. Along the same lines, the user can also perform a capture of the vehicle diagnostic communications traffic and send it through email to RSW solutions for help with certain systems. This will help not only diagnose problems with the end user vehicle but will help me further develop for the software with different user vehicles out in the world.
I have also ordered a spare second hand 2005 L322 Range Rover Body Control Module. I will then be able to play with the different Body Control module configuration strings that exits on the later L322 Body control module units. As I do not have access to a 2005 L322 vehicle, this is the next best thing to use as a test platform. I know a large number of people want the Body Control module configuration module back up and running on the All Comms Software. This will bring me one step closer to getting the BCM module activated again.
