What is an Infiniti Premium M37 airbag control unit?
The Infiniti Premium M37 airbag control unit is your vehicle's central safety unit, precisely activating all occupant restraint systems in the event of a crash. It continuously monitors sensors, stores crash data, and ensures the proper functioning of all Supplemental Restraint System (SRS) components to maximize your safety.
This essential module is responsible for the intelligent control and monitoring of all airbag system components. It processes signals from crash sensors and deploys front, side, and curtain airbags, as well as seat belt pretensioners, as needed.
Why is the Infiniti Premium M37 airbag control unit defective?
The Infiniti Premium M37 airbag control module often malfunctions because it stores crash data after an accident, triggering a fault condition and activating the airbag warning light. Repair is necessary because this stored data prevents the airbag system from operating until the module is professionally reset.
In addition to accidents, power surges, water damage, or internal electronic component failures can also affect the control unit. A failure is usually indicated by a permanently illuminated airbag warning light on the dashboard.
A defective module cannot process new crash information or deploy airbags correctly. This poses a significant safety risk and requires immediate professional diagnosis and repair of the Infiniti Premium M37 airbag control unit.

When diagnosing a faulty Infiniti Premium M37 airbag control module, specific error codes will appear, indicating internal problems or communication issues within the module. These codes, often in the B range, signal the need for professional inspection or a reset to restore full functionality of the safety system.
- B1000 → Control unit communication error → General communication fault of the airbag control unit.
- B1018 → Passenger occupancy sensor (OCS) error → The airbag control unit detects a faulty transmission from the occupancy sensor.
