Compare Nissan airbag repair quotes from specialist garages

Airbag systems work thanks to onboard sensors that detect when a car has crashed. A small explosive device in the airbag module detonates, inflating the airbag, which protects the driver and passenger from impact with the front of the car.

This system has several components: the ECU, ignitor, sensors, inflator, warning lights, passenger occupancy sensors and the airbags themselves. If one or more of these develops a fault, you'll need to book a car airbag repair as soon as possible.

The most obvious sign you need an airbag ECU repair is the Supplemental Restraint System (SRS) warning light. When the airbag warning light comes on and stays on, an airbag light repair may be required, though the problem is likely related to the system rather than the light itself. In fact, the light may indicate a sensor problem, in which case you'll need to book a car airbag sensor repair.
