Remote Climate Control

2011-2013 models

Gen1 Cars (2011-2014) require a hardware modification to enable OVMS to control remote climate. Wire RC3 to TCU pin 11, more info

2014-2016 models

To use OVMS to activate remote climate the Nissan TCU (Telematics Control Unit) module must be unplugged if fitted (only on Acenta and Tekna models). The TCU is located behind the glovebox on LHD cars or on the right hand side of the drivers foot well on RHD cars. The large white plug on the rear of the TCU should be unplugged, push down tab in the middle and pull to unplug, see video for RHD cars and this page for LHD cars.

Note: Unplugging the TCU will disable Nissan EV connect / CARWINGS features e.g Nissan mobile app. All other car functions will not be effected e.g GPS, maps, radio, Bluetooth, microphone all work just the same as before. OVMS can be used to more than substitute the loss of Nissan Connect features. The TCU can be plugged back in at any point in the future if required.

OVMS remote climate support will ‘just work’ on LEAF Visia models and Visia/Acenta e-NV200 since these models do not have a TCU fitted.

Note: If you prefer not to unplug the Nissan TCU, all OVMS functions appart from remote climate will function just fine alongside the Nissan TCU.

2016-2017 models

Remote climate control may not work on 2016-2017 cars. This is because in 2016 Nissan moved the TCU from the EV CAN bus to the CAR CAN bus.

Set the model year as follows and if necessary configure 30 kWh model:

config set xnl modelyear 2016


config set xnl modelyear 2017

Note: in latest OVMS fimware version model year and battery size can be set via the web config interface.

30 kwh models

For models with a 30 kwhr battery pack, set the capacity manually as follows:

config set xnl maxGids 356 config set xnl newCarAh 79

Note: in latest OVMS firmware version model year and battery size can be set via the web config interface.

2018+ models

2018+ 40kWh LEAF is not yet supported. Please get in touch if your interested in helping to add support. Relevant 2018 CANbus messages have already been decoded and documented, see MyNissanLEAF thread.

Range Calculation

The OVMS uses two configuration options to calculate remaining range, whPerGid (default 80Wh/gid) and kmPerKWh (default 7.1km/kWh). The range calculation is based on the remaining gids reported by the LBC and at the moment does not hold 5% in reserve like LeafSpy. Feedback on this calculation is welcomed.


Assistance is appreciated as I haven’t had time to try to override the TCU using the OVMS or find an alternative solution to prevent the TCU overriding the messages while still allowing the hands free microphone to work.
