CAN COMMUNICATIONPFP:23710
System DescriptionECS007QX
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

Precautions When Working On ABSNJBR0140Use recommended tyres in combination with ABS.
Please fit tyres or studded tyres, etc. with the same size.
If different sizes of tyres, or tyres other than the ones rec-
ommended for use with the ABS, are fitted, stopping dis-
tance will increase and control and stability could deterio-
rate.
When changing brake pads, please use Nissan genuine
parts.
When fitting radios etc, do not position the radio itself,
antenna, or antenna cables within an area of about 100
mm (3.94 in) of the control unit.
When doing any work that requires electro-welding, first
remove the control unit.
Please take care when taking a power supply for the
audio, lamps etc., not to take this from any ABS-related
harness. (Please refer to the electrical wiring diagrams for
ABS-related harnesses)
Wiring Diagrams and Trouble DiagnosisNJBR0003When you read wiring diagrams, refer to the following:
GI-12, “HOW TO READ WIRING DIAGRAMS”
EL-12, “POWER SUPPLY ROUTING”
When you perform trouble diagnosis, refer to the following:
GI-33, “HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSIS”
GI-22, “HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENT”
On board self-diagnosis is available everywhere except for Europe.
