Infiniti QX60 L50 airbag control unit repair

What is an Infiniti QX60 L50 airbag control unit?

The Infiniti QX60 L50 airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It continuously monitors all airbag sensors, stores relevant crash data, and ensures precise deployment of the airbag modules and seatbelt pretensioners to maximize occupant safety.

This module, also known as the SRS control module, is the brain of the passive safety system in your vehicle.

It is crucial for the proper functioning of front, side and curtain airbags as well as seat belt pretensioners.

Why is the Infiniti QX60 L50 airbag control unit defective?

An Infiniti QX60 L50 airbag control module typically fails because it stores crash data after an impact or fails due to internal electronic errors. After an accident, the module is often locked and must be reset or replaced to restore safety functions.

After a collision, the control unit stores irreversible crash data, which results in the system being immediately locked.

Internal component defects or water damage can also lead to module failure, which impairs the function of the entire airbag system.

Common error codes for Infiniti QX60 L50 airbag control unit repair

Specific trouble codes exclusively assigned to the Infiniti QX60 L50 airbag control unit are not publicly available; diagnosis is typically performed using general B-codes that indicate problems with the airbag system. Infiniti QX60 L50 airbag control unit repairs often display nonspecific system errors.

These general error codes indicate a malfunction of the control unit or its components without specifying a detailed cause.

A reset service can delete the stored crash data and make the module functional again.

• B1000 → Control unit communication error → interrupted data connection or internal module error.
• B1010 → Airbag control unit internal error → Defect in the internal electronics of the control unit.
• B1040 → Airbag block circuit error → Problem in the circuit or logic of the airbag module.
• B1100 → Airbag diagnostic logic error → Malfunction in the control unit's self-diagnosis function.

What part numbers are available for the Infiniti QX60 L50 airbag control unit repair?

For the Infiniti QX60 L50 airbag control unit repair, the original OEM part numbers 988209NB0A from Infiniti and the corresponding supplier number 0285012283 from Bosch are 100% verified and compatible. These numbers are crucial for selecting the correct replacement part.

The Infiniti part number 988209NB0A identifies the original part from the vehicle manufacturer.

The Bosch part number 0285012283 is the equivalent number of the original equipment supplier, which confirms the OEM quality.

No other exact OEM alternative numbers are known for this specific airbag control unit for the QX60 L50, which simplifies identification.

Important technical details and functions of the Infiniti QX60 L50 airbag control unit

The Infiniti QX60 L50 airbag control unit is a central safety module that operates at 12 volts and features integrated collision sensors and interfaces to external sensors. Its functions include precise control of airbag deployment and seat belt pretensioners in the event of an accident, as well as storing crash data for diagnostic purposes.

The factory programming of the control unit is vehicle-specific and tied to the VIN, which requires reprogramming if it is replaced.

Reputable repair providers typically offer a warranty of 90 days to one year on tested modules.

Compatible vehicle models and years of manufacture for the Infiniti QX60 L50 airbag control unit repair

This control unit is designed specifically for the Infiniti QX60 L50 series.

It fits various model years; however, a precise comparison with the original part number is always required, as variants may exist for older (e.g. 2015) or newer (e.g. 2022-2023) models.

Installation is only possible in vehicle variants with SRS equipment as standard.

Functionality and features

The module detects vehicle collisions using integrated accelerometers and external satellite sensors to determine the severity and type of impact.

Depending on this data, it specifically activates the appropriate airbags and belt tensioners to maximize occupant protection.

A continuous self-diagnosis monitors all SRS components; if a malfunction occurs, a warning light is activated in the dashboard.

All relevant error and crash data are stored for later workshop diagnosis.

Installation position and connections

The airbag control unit is typically located in the vehicle interior, often under the middle seat or in the middle footwell.

This central positioning minimizes the cable lengths to the airbag sensors and modules.

It has several connectors for data and power supply as well as interfaces to airbag sensors and the vehicle diagnostic system (e.g. OBD-II).

The mechanical fastening is carried out securely on the vehicle floor or frame by means of screw connections.

Special features and variants

When it comes to replacement modules, it should be noted that although they are tested, they are often not programmed to the specific vehicle VIN, which requires adaptation by the dealer.

Specialized providers offer a reset service that makes a triggered original control unit operational again without dealer programming.

For a safe Infiniti QX60 L50 airbag control unit repair, strict safety guidelines, such as disconnecting the battery, must always be followed.

Depending on the model year and equipment, for example in hybrid versions, different control units with varying sensor integration can be used.

Careful matching of part numbers is essential when replacing to ensure compatibility.
