Cheap Nissan Leaf Airbag Control Module

Yes, all generations of the Nissan Leaf are fitted with an airbag control module (also called the SRS control unit) as standard — it manages the deployment of airbags and pretensioner seat belts throughout the car. Because the Leaf is an electric vehicle with no engine variants to worry about, every Leaf on UK roads has one. If your warning light is on or the module has been triggered in an accident, a used unit from a breaker is a common repair route, but always bear in mind that airbag modules are safety-critical components and must be professionally installed and tested.

The Nissan Leaf runs in two well-established generations: the first-generation (Mk1, 2011–2017) and the second-generation (Mk2, 2018 onwards). These generations have different SRS system layouts and wiring architectures, so a module from a Mk1 is very unlikely to be compatible with a Mk2 and vice versa. You should confirm exact compatibility with the breaker using your registration number before purchasing, as crossing the generation boundary is a route where fitment cannot be assumed.

The airbag control module itself is not typically a trim-specific component, so in most cases the same unit is used across Visia, Acenta, and Tekna variants within the same generation. However, trim level can influence the number of airbags fitted (for example, side curtain or knee airbags on higher trims), which may mean the module is configured differently — confirm with the breaker that the unit from their donor car matches the airbag count and SRS setup in yours. Providing your registration to the breaker is the safest way to verify this.

The Nissan Leaf has only ever been sold as a 5-door hatchback in the UK, so door count is not a variable you need to worry about when sourcing a used module. What matters more is matching the generation and confirming the SRS configuration matches your specific car, which the breaker can check against your registration.

Airbag control modules are safety-critical components — an incorrectly fitted or uncoded module can prevent airbags from deploying in a crash or cause accidental deployment, both of which are extremely dangerous. Professional fitting and post-installation coding or reset by a technician with the appropriate diagnostic equipment is strongly recommended. Additionally, if your current module was triggered in an accident, it is a single-use item and must be replaced rather than repaired.

Both a 2014 and a 2017 Leaf fall within the first-generation (Mk1, 2011–2017) range, so you are staying within the same generation, which is a good starting point. However, whether the specific SRS system configuration and module part number are compatible between those two model years is something you must confirm with the breaker against your registration, as there can be running changes within a generation. Never assume compatibility without the breaker cross-referencing the part numbers.
