Editing CAN Buses

The Nissan Leaf uses multiple CAN buses. The two most researched and most important are EV-CAN and CAR-CAN.

== CAR-CAN (or VEHICLE CAN) ==
This bus connects various low-voltage control systems, including:

* [[Vehicle Control Module (VCM)]]
* [[Intelligent Power Distribution Module (IPDM)]]
* [[Combination Meter]]
* [[Vehicle Sound for Pedestrians (VSP) module]]
* [[Body Control Module (BCM)]]
* [[CAN Gateway]]

== EV-CAN ==
This bus connects the high-voltage components, plus the VCM. Devices on this bus:

* [[Vehicle Control Module (VCM)]]
* [[Traction Motor Inverter]]
* [[Power Delivery Module (PDM)]]
* Air Conditioning system
* [[Lithium Battery Controller (LBC)]]
* [[CAN Gateway]]

== CHASSIS-CAN ==
Devices on this bus:

* Steering angle sensor
* EPS control unit
* [[Chassis Control Module]]
* Electric parking brake
* Brake control module
* ABS system
* [[CAN Gateway]]

== ADAS-CAN ==
Stands for "Advanced Driver Assistance System".

Devices on this bus:

* ADAS control unit
* [[Chassis Control Module]]
* [[CAN Gateway]]

== ITS-CAN ==
May stand for "Intelligent Transportation Systems".

Devices on this bus:

* [[Around View Monitor Control Unit]]
* Side radars (left and right)
* Distance sensor
* Lane camera unit
* ADAS control unit
* [[CAN Gateway]]

== AV-CAN ==
Only for ZE0/AZE0. Connects the buttons surrounding the [[AV Control Unit]] to the [[AV Control Unit]].

== IT-CAN ==
May stand for "Information Technology".

The functionality of the IT-CAN bus is not well-documented. Devices on this bus:

* [[Telematics Control Unit (TCU)]]
* [[AV Control Unit]]
* [[CAN Gateway]]

== M-CAN ==
Devices on this bus:

* [[Telematics Control Unit (TCU)]]
* [[Combination Meter]]
* [[AV Control Unit]]
