What is an Infiniti Journey G35 airbag control unit?
The Infiniti Journey G35 airbag control unit is the central safety unit that activates all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors sensors in the vehicle, stores important crash data, and thus ensures the proper function and safety of all passive restraint systems in the event of an impact.
This module, also called the SRS airbag computer, is responsible for diagnosing and controlling the entire airbag system. It receives signals from acceleration sensors and makes lightning-fast decisions about whether to deploy the necessary airbags.
The correct function of the control unit is crucial for occupant safety and is checked during regular vehicle maintenance.
Why is the Infiniti Journey G35 airbag control unit defective?
The Infiniti Journey G35 airbag control unit often fails because it stores crash data after an accident, preventing the module from being reused and activating the airbag warning light. Internal electronic errors, surges in the electrical system, or corrosion can also lead to failure, necessitating an Infiniti Journey G35 airbag control unit repair or replacement.
When the control unit detects an impact, a crash event is stored in its internal memory. This record prevents normal function, even if the module is physically undamaged, and requires a reset or repair.
A failure may also be indicated by a permanently illuminated airbag warning light or specific error codes, even without a previously recorded accident.
Common error codes for Infiniti Journey G35 airbag control unit repair
During an Infiniti Journey G35 airbag control module repair, specific error codes often occur, indicating a malfunction or accident within the control module itself, rather than with sensors or other components. These codes often require a module reset or reconfiguration after a replacement to restore the safety systems to working order.
- B1000 → Control unit communication error → Cause: Problem with the internal communication or wiring of the airbag ECU.
- B1425 → Rear collision detected → Cause: The airbag module has registered a rear collision and needs to be reset.
- B1427-55 → Airbag computer module replaced, needs to be configured → Cause: A new or used module was installed and requires vehicle-specific VIN coding.
- B14XX → Airbag Computer Module Error (General) → Cause: A general internal error in the airbag control unit, which often requires a reset.
- U1010 → Airbag Control Unit CAN communication error → Cause: Malfunction in the data communication via the CAN bus to the airbag control unit.
These error codes primarily relate to the control unit itself and must be taken into account during diagnosis. A workshop can read these error codes and initiate the necessary steps to resolve the problem.
What part numbers are available for the Infiniti Journey G35 airbag control unit repair?
For Infiniti Journey G35 airbag control module repair, the exact Infiniti OEM part number 98820-AC70A is the primary reference for finding the correct replacement or repair part. This number identifies the central airbag control module, which fits vehicle models from 2003 to 2008, ensuring precise compatibility.
Part number 98820-AC70A is used by Infiniti as a genuine replacement part for the airbag control module. It's crucial to note this number when purchasing to avoid compatibility issues.
Make sure it is the control unit and not airbag sensors or other sub-modules that have different part numbers.
Infiniti Journey G35 Airbag Control Unit Technical Specifications and Compatibility
The Infiniti Journey G35 airbag control module, an SRS Airbag Computer Diagnostic Control Module, is designed for Infiniti G35 models from 2003 to 2008, including the Journey variant. It is designed for the 12V electrical system, communicates via the CAN bus, and is critical to the safety systems. After installation, it must be programmed to the specific vehicle identification number (VIN).
The module monitors all relevant components of the Supplemental Restraint System, such as front, side and head airbags as well as the belt pretensioners.
It processes signals from acceleration sensors and controls the pyrotechnic deployment of the airbags in an emergency. The diagnostic function stores error codes that enable targeted repair of the Infiniti Journey G35 airbag control unit in the event of a failure.
The installation location is typically in the vehicle center tunnel under the dashboard, where it is securely bolted and connected to the vehicle network.
Used modules must be reprogrammed to the vehicle in a specialist workshop, as each control unit is coded specifically for that vehicle and otherwise the airbag warning light will remain lit.
