dickandlois Report post Posted August 7, 2021 (edited) This is a file of sources to find out how the CAN(Closed Area Network) works on the Chassis of the newer Vehicles and even some of the older vehicles. This system was introduced around 2000 / 2005 model year chassis that allows all the different system modules to communicate with each other. The system is active between the ECM anTCM and the Dash display of the vehicles. It is in many ways like the computer networks you own to control everything in your smart house remotely. The newer the Car, Truck, RV the more complicated the systems are. The list is simple and there are many other sources of information. Depending on ones age , you might need to interact with your kids or grand kids ! The System information is not included in the owners manuals and many Service centers do not have the trained Tech's to work on this system. The biggest issue from my point of view is the fact that the system works on low voltage and the connection are exposed to the elements under the Vehicle Chassis.

YES!! The slightest bit of corrosion in a connection will make the system inoperable. When I say “slightest” I mean barely detectable by the human eye its DONE! The manufacturers should have used gold pins they are so sensitive! Share this post Link to post Share on other sites
