The Leaf’s brake ‘booster’ features it’s own integral control unit which interacts with other control units in the vehicle. It has the ability to command light braking requirements to be performed through regenerative braking using the traction motor only or by a combination of this and the hydraulic brakes.
Nissan has released many firmware updates for the electrically-driven intelligent brake control module in different models of the Nissan Leaf. Some of these updates relate to improved performance and others to safety. Unfortunately, in New Zealand the majority of these updates have not been made available by Nissan New Zealand to their franchised dealers.
With ZE0 (2011/2012MY) models, a firmware update is available which is reported by Nissan to improve the overall brake sensitivity at low speed. The graphic below shows the firmware versions to check if a car requires an update or not. This information is available on many diagnostics tools including the Pro version of LeafSpy.
Bookings are essential as the equipment required for this update are not always on site.
