GMLAN and CAN Repairs
NOTE:
When making a repair to any GMLAN or CAN network, the original wire length after the repair must be the same length as before the repair. If the network is a twisted pair, the twist must be maintained after the repair is completed.
Low speed GMLAN has a single wire and communicates at a slower speed. High speed GMLAN and CAN has two wires in a twisted pair and works at higher speeds. For more information on GMLAN and CAN serial data protocol, refer to Data Link Communications Description and Operation .
