Hello,

I am currently undertaking some research surrounding CAN bus. I am interested if anyone knows what stateful information flows over the CAN bus (preferably sensor data)? I am currently looking at Vauxhall Corsa C (2004 onwards with Full CAN bus), but if you know anything regarding other models, that works too.

For example, wheel speed sensors might send information that is held by the ABS system in some way. What other data might be stateful in this context?

For more context, out of the following sensors, which are likely to just be dumb terminals and which are likely to transmit stateful information:

ABS, TCS, ESC - Wheel speed sensor
Engine - Camshaft sensor (Ignition), Coolant/Oil temperature sensor, Crankshaft sensor (Ignition), Knock sensor (Ignition), Lambda sensor, Mass air flow sensor, Accelerator position sensor, Throttle position sensor
General - parking sensors, exterior temperature sensor, fuel temperature sensor, speed sensor (RPM - Automatic transmission vehicles)
