SYSTEM

CAN COMMUNICATION SYSTEM : CAN Communication Control Circuit

INFOID:0000000009174943

CAN communication control circuit is incorporated into the control unit and transmits/receives CAN communi-

cation signals.

*: These are the only control units wired with both ends of CAN communication system.

CAN COMMUNICATION SYSTEM : CAN System Specification Chart

INFOID:0000000009174944

Determine CAN system type from the following specification chart.

NOTE:

Refer to 

LAN-20, "Trouble Diagnosis Procedure"

 for how to use CAN system specification chart.

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.
