Scantool <--> SDLC <--> Rest of Car
I *think*, the scantool will always run at highspeed CAN (500kb/s) when communicating to the SDLC, even when communicating to the MS Pins (3,11).
For example, We send a simple command over the MS Pins to the SDLC of: 7D0 01 20
(The above is a simple request for 'are you present' to the headunit)
The SDLC then does the hard work, figures out which of the comms it needs to send the command, and then sends it at the correct speed if required (Such as standard MS CAN speed).
Any responses back from the module will be picked up by the SDLC, and spat back out on the MS Pins to the scantool.
What Im unsure about, is if any special commands need to be sent to the SDLC first to tell it which 'route' to take to send the command. Or, if it simple sends all commands.. over all CANs it has connected for those pins.
