A little Can Bus tutorial

[Knizar]

Clarification on CAN-BUS.

The CAN-BUS protocol is about messages not devices.

That is, every device on the bus broadcasts it's messages with specific identifiers and every device listens to all messages ignoring all but those having the specific identifiers of interest.

==========

Conceptual explanation of the relationship between CAN-BUS and OBD-II.

CAN-BUS is how the Spyder talks* to itself.

OBD-II is how the Spyder talks* to us.

* talks using CAN-BUS messages.

I must be CAN-BUS because after reading this you have me " Talking to MYSELF ", I'm a bit hard of hearing, but the OBD-II must not be working because I haven't heard a word out of my Spyder! Thanks for the info though. Bill
