Editing Nissan Leaf

This is the '''Nissan Leaf Wiki''', the first (and only) vehicle wiki of '''Car Hacking Wiki'''. It focuses on the technical internals of the Nissan Leaf. Expect to find details about the components and subsystems that make up the Leaf, electrical, electronic and data specifications, information on known modifications and projects, etc. This is a wiki, so if you have some info, add it in!

Car Hacking Wiki is designed to be a resource that goes into as much depth as possible about cars, their components, their firmware, etc. It starts with the Nissan Leaf, with the dream of growing into a family of wikis covering many different vehicles.

== Generations ==

=== First generation (ZE0, AZE0) ===
[[File:Nissan Leaf CRI 02 2023 1923.jpg|thumb|Gen 1 Nissan Leaf]]
The first-generation Leaf features a 24kWh or 30kWh battery and an 80kW motor.

==== ZEO (2011-2012) ====
The original Leaf

==== AZE0 (2013-2017) ====
Often referred to as Gen 2 ''before'' the ZE1 was introduced, thereafter sometimes called Gen 1.5. This revision of the Leaf kept the appearance the same, but included several technical changes and improvements.

Changes from ZE0:<ref>https://samholford.github.io/leafguide/</ref>

* Improved battery chemistry
* 80 kg weight reduction with aluminium doors and bonnet (in [[JDM]] models)
* More boot space
* Hill start assist
* Charge plug lock + light
* Insulated ceiling
* Enhanced brake regeneration (B mode) on some trims
* Heat pump instead of resistive heating (on some trims)

=== Second generation (ZE1) ===

The second-generation Leaf features a 40kWh battery with 110kW motor output, or a 62kWh battery with 160kW motor output.

It adds major new features such as ProPilot, automatic parking and one-pedal driving, besides the new look and feel.

== Components ==
Where it makes sense, this section is organised and components are named in accordance with the ZE1 service manual. This is to provide some kind of standard, and also hopefully make it easier to look up disassembly instructions related to the component in question.

=== Electric Powertrain ===
* [[Lithium Ion Battery]]
* [[Traction Motor]]
* [[Traction Motor Inverter]]
* [[Power Delivery Module (PDM)]] - this includes the On-board Charger (OBC) and DC-DC Converter

=== Driver Information & Multimedia ===
* [[Combination Meter]] (instrument cluster)
* [[AV Control Unit|AV control unit]]
* [[Around View Monitor Control Unit]]
* [[Telematics Control Unit (TCU)]]

=== LAN and Diagnostic ===
The Nissan Leaf uses multiple CAN buses.

Main article: [[CAN Buses]]

* [[CAN Gateway]] (ZE1 only)
* [[OBDII Port]]

== Markets ==

* [[Japanese Domestic Market (JDM)]]
* [[North American Market (NAM)]]

== Trim levels ==
There are three main trim levels, which are named differently in different markets.<ref>https://evdb.nz/v/nissan-leaf</ref>

== Service Manuals ==
There are a few ways to obtain service manuals.

* Some can be accessed from an official Nissan website (https://www.nissan-techinfo.com/find.aspx), for a fee. Access can be purchased for periods of 1 day ($35 USD) up to a year ($1250). This is only available for the [[North American Market (NAM)]]. These manuals cover every model year and include an electronic service manual (same as in the link below), electronic wiring diagram (which is not available for free in any other known location at the time of writing), and a PDF version of the wiring diagram also as per the link below. The Electronic Wiring Diagram can be retrieved for offline use using the [https://github.com/GeorgeDewar/nissan-ewd-fetcher/tree/main nissan-ewd-fetcher] script.
* A ZE1 service manual (NAM) is available at https://www.mediafire.com/file/yoikgbj1l8l7qwi/SM18EA0ZE1U8.zip in the form of an interactive HTML manual, plus a PDF wiring diagram
* The ZE1 Electronic Wiring Diagram is mentioned on [https://mhhauto.com/Thread-Nissan-Leaf-ZE1-2021-Service-Manual-Wiring-diagrams this forum post] on mhhauto.com.
* 2011-2015 service manuals can be found for free at https://www.nicoclub.com/nissan-service-manuals, in the form of a PDF file per system. However, this forum requires a fee to subscribe, and the person selling this copy charges a fee, so it's actually cheaper to pay Nissan for access. A savvy user may be able to download a copy of the electronic wiring diagram however this would require a reasonable amount of scripting (XML files need to be parsed to enumerate the SVG files used for diagrams).
* Various websites have ZE0 service manuals available for sale.

== Useful Tools ==

=== Official Tools ===
Nissan dealerships use [[CONSULT-III plus (C-III Plus)]] to diagnose problems, perform service procedures (like pairing an [[AV Control Unit]] to the car) and update the firmware on ECUs. It connects to the vehicle via the [[OBDII Port]].

=== Third-Party Tools ===
[https://play.google.com/store/apps/details?id=com.Turbo3.Leaf_Spy_Pro LeafSpy] is an Android app which connects via a Bluetooth OBDII dongle, and can perform many functions such as displaying battery health information, clearing [[DTCs]], changing settings inside some of the ECUs, logging data, etc.
