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.
CAN Communication
Real-time communications (signal exchanges) are maintained among the control units such as the CVT, C/U, ECM, combination meter etc. Each unit is controlled optimally depending on vehicle driving conditions while sharing information and in cooperating with the other control units.
In CAN (Controller Area Network) communication, control units are connected with two communication lines (CAN-H line, CAN-L line) allowing a high rate of information to be transmitted by fewer wirings. Each control unit transmits/receives data but selectively reads required data only.
