    Disagree.
    What you see there is a CAN frame with headers stripped off. That is a request to $AE service, used in diagnostic modes to test actuators, devices etc

    Im curious... what car is it? Whats the ARB ID of this BCM?

    It seems this thread just died.... Time to resurrect

    Is there a document which defines the communication protocol used to issue the commands. For example, J1979 is used for OBDII, what is the equivalent for SW CAN?

    Are there any DIY pages for SW CAN?

    If there is a controlling document that defines the message format and which messages that are available

    I have a project I will be working on here shortly where I will be doing some stuff with this so I would also appreciate any knowledge that can be shared.

    I have an '03 Chevy Avalanche and plan to start "hacking" the LAN bus in this truck. Eventually I want to talk to the BCM to be able to do things such as turn on lights, adjust the seats etc... I want to replace the OEM stereo with a carpc so I want to learn how to communicate with the devices hooked to the radio. Such as the steering wheel controls, rear entertainment center, XM radio etc... Once I can mimic my Stereo I will pull the stereo and use fully with my PC. I will move onto things such as the HVAC controls and whatever else can be controlled so I can either replace the standard interface with a PC or access them in parallel.

    Information I have gathered so far is that is appears all of the buses in the truck talk with the same ODBII style communications. Have not yet tried to do it though. I will be installing a pc into my truck in the next week or so and will have a scantools unit to start playing with it.
