Remote Climate Control¶
Gen1 Cars (2011-2014) require a hardware modification to enable OVMS to control remote climate. Wire RC3 to TCU pin 11, more info
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.
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.
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.
- Nissan LEAF supported added by Tom Parker, see his wiki for lots of documentation and resources. Some info is outdated e.g climate control now turns off automatically.

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.
