Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Controller Area Network
Controller Area Network (CAN) link is used by vehicles equipped with V6 engine. CAN data link is used by Engine Control Module (ECM), Transaxle Control Module (TCM) and Body Control Module (BCM). BCM can communicate on both CAN link and class-2 serial data link. Information sent over CAN link to BCM is converted to a class-2 serial data message to Data Link Connector (DLC). CAN link is not connected to DLC and is used only for sharing information between control modules.
