The airbag technology used in the Infiniti M37 varies depending on the model year and model series. Airbag control units for the Infiniti M37 (Y51 series) are specifically tailored to its safety architecture and guarantee true-to-original functionality after professional repair.
The Infiniti M37 belongs to the fourth and final generation of the M-series produced under this name. This Y51 series was manufactured from 2010 to 2013 before being continued as the Infiniti Q70 in 2014.
The development of the airbag system in the Infiniti M37 Y51 reflected the state of the art at the time. It already included an advanced airbag system with multiple protective components designed for occupant safety.
The Infiniti M37 is part of the Y51 series, which represents the fourth and final generation of the Infiniti M-series. There were no separate facelifts within this model line, as the model change to the Infiniti Q70 took place in 2014.
The entire production history of the Infiniti M-Series spans four main generations. The first was the M30 (1990–1992), followed by the M45 Y34 (2003–2004), and the third generation, the M35/M45 Y50 (2005–2010).
The Infiniti M37, along with the M35h and M56, represents the fourth generation (Y51), which was built from 2010 to 2013. Each of these generations used specific airbag control units tailored to the respective vehicle architecture and safety features.
Infiniti M37 airbag control units can be identified by their unique part number, the exact year of manufacture, and the vehicle identification number (VIN). Specific control unit variants are installed for the Infiniti M37 Y51 series (2010-2013), which are crucial for the correct functioning of the complex safety system.
The airbag control unit part number is located directly on the component's housing. It is crucial to ensure compatibility during repair or replacement and to ensure proper communication with other vehicle systems.
Since the Infiniti M37 Y51 has a limited production run, identification is generally straightforward. However, it's important to consider all relevant data, such as the year of manufacture and VIN, to accurately identify the correct control unit.
The Infiniti M37 Y51 series (model years 2010-2013) features a comprehensive standard airbag package designed for maximum occupant safety. The trim level primarily affected additional driver assistance systems, not the core airbag modules.
The Infiniti M37 comes standard with the Infiniti Advanced Air Bag System (AABS). This system includes dual-stage front airbags for the driver and front passenger that adjust their deployment strength based on the severity of the impact. It also includes integrated seatbelt and occupant detection sensors.
Additional protection is provided by standard side airbags in the front seats, which protect the head and chest areas of the occupants. Roof-mounted side curtain airbags are also installed for the front and rear outer seats, providing protection in the event of a side impact or rollover.
The 3-point seat belts also contribute to passive safety, with the driver's belt equipped with an emergency locking retractor (ELR). Active front head restraints, which reduce the risk of whiplash in a rear-end collision, as well as front and rear crumple zones and increased body rigidity with side reinforcements, round out the comprehensive safety package.
Additional safety features could be optionally added to the Infiniti M37 of the Y51 series. These included pre-crash seat belts for the front passengers, which were included in certain packages and could tighten in the event of an impending collision. Advanced driver assistance systems such as lane departure warning and adaptive cruise control were also available as optional packages, further complementing the overall vehicle safety concept.
