What is an Infiniti Sport G37S airbag control unit?
The Infiniti Sport G37S airbag control unit is the central safety unit in your vehicle, precisely activating all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors crash sensors, stores important data, and ensures the correct functioning of all airbag modules for maximum occupant safety.
This essential module continuously monitors signals from crash sensors. If specified thresholds are exceeded, it triggers the airbags and seatbelt pretensioners.
It controls various firing circuits for front, side, and curtain airbags. Multiple sensor interfaces are also integrated for comprehensive monitoring.
The Infiniti Sport G37S airbag control unit is typically installed under the dashboard or in the center console. There, it is optimally positioned for networking with all relevant sensors and actuators.
Why is the Infiniti Sport G37S airbag control unit defective?
The Infiniti Sport G37S airbag control unit often malfunctions because it stores crash data after an accident, which inhibits its function, or is affected by internal communication errors and power surges. These problems often require a professional Infiniti Sport G37S airbag control unit repair to restore full safety.
The most common reason for a defect is the storage of crash data after an accident. This data blocks the system until it is professionally deleted.
Internal electronic faults or age-related wear and tear can also cause a failure. In such cases, a diagnosis is essential to determine the cause and repair the Infiniti Sport G37S airbag control unit.
Communication errors or an open circuit in the module can also cause the control unit to be reported as defective. A precise diagnosis is crucial to avoid unnecessary part replacements.
Common error codes for Infiniti Sport G37S airbag control unit repair
When diagnosing a faulty Infiniti Sport G37S airbag control unit, specific error codes will appear that directly indicate problems with the unit itself. The most common codes include B1000 for communication errors, B1015 for stored crash data, and B1018, which signals an open driver airbag module and requires specialized Infiniti Sport G37S airbag control unit repair.
- B1000 → Control unit communication error → Indicates a faulty connection or an internal error in the airbag control unit.
- B1015 → Airbag control unit crash data storage / communication error → Occurs after an accident and requires a reset of the crash data in the module.
- B1018 → Driver airbag module open → Indicates an open circuit or a faulty connection to the driver airbag module.
It's important to note that sensor-related trouble codes, such as B1139, are excluded in this context. These codes focus exclusively on the control unit itself and its direct functionality.
What part numbers are available for the Infiniti Sport G37S airbag control unit repair?
For Infiniti Sport G37S airbag control unit repairs, specific, verified OEM part numbers are critical to ensure compatibility. These include original numbers such as K851M-JK600 (driver side) and Y851E-JL60A (passenger side), as well as their replacement numbers, which are directly linked to the Infiniti G37S modules and enable precise identification.
- K851M-JK600 → Manufacturer: Infiniti → Type: Original Airbag Control Unit (Driver's Side)
- Y8E10-JK600 → Manufacturer: Infiniti → Type: Replacement/Update for K851M-JK600 (driver's side)
- Y851E-JL60A → Manufacturer: Infiniti → Type: Original Airbag Module (Passenger Side)
- Y8EH0-JL60A → Manufacturer: Infiniti → Type: Replacement airbag module (passenger side)
- K85PA-JL00A → Manufacturer: Infiniti → Type: Original curtain airbag module (driver's side)
These OEM part numbers are specifically designed for the Infiniti G37 model series (2008-2013). They are specifically designed for the Sport G37S with the 3.7L engine (VQ37VHR).
It's important to note that specific supplier OEM numbers, such as those from Bosch or Continental, are rarely publicly available. Infiniti predominantly uses its own internal part numbers for these components.
Some service providers offer a module reset that restores the control unit's functionality after an accident. This service often eliminates the need to purchase a new unit and is a cost-effective option for Infiniti Sport G37S airbag control unit repair.
