Can Communication Control Circuit
WARNING: This page is about a different car, the 2017 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.
CAN communication control circuit is incorporated into the control unit and transmits/receives CAN communication signals.
| Component | System description |
|---|---|
| CAN controller | It controls CAN communication signal transmission and reception, error detection, etc. |
| Transceiver IC | It converts digital signal into CAN communication signal, and CAN communication signal into digital signal. |
| Noise filter | It eliminates noise of CAN communication signal. |
| Termination circuit* (Resistance of approx. 120 Ω) |
Generates a potential difference between CAN-H and CAN-L. |
* : These are the only control units wired with both ends of CAN communication system.
