Lets Talk GMLAN (J2411 SWCAN-Bus)

[Wnts2Go10O]

No where else i could think to put this but:

a couple q's as i want as many opinions, view points, etc.. just dont go on and on with the 'cant, wont, dont' bs please.

i have found out through the use of google and other sources that:

-the bcm is commanding other modules in the network (a central hub of sorts). at least for the radio, locks, etc.
-the brake control module has all the sensor inputs for the suspension
-low speed SWCAN is for button presses (doors, radio, etc)
-there ARE SWCAN readers and the like that will read high and low with some... DIY... if you wanted a less expensive option
-simulators for other cars' CAN-Bus systems, again.. expensive if you arent a DIY'er

the questions are:

what is the suspension controller or PCM doing to translate the data into data that is plugged into the models used to run the engine, suspension, etc?

what could be used to simulate the 5v sensor inputs over the network?

how would one go about setting up a simple bench station for such a thing?

and

what could one do to recreate the network in a more compact way (sensor inputs and command in one module)? though, i suspect THAT is the 64,000 dollar question.

ohhh! this is useful!:
