What is a Honda Ridgeline YG2 airbag control unit?
The Honda Ridgeline YG2 airbag control unit is the central safety unit in your vehicle, activating 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 ensures the proper functioning of the entire airbag system to maximize your safety.
This electronic control unit, also known as the SRS Control Module, is essential for the passive safety of the Honda Ridgeline YG2 from model years 2017 to 2023. It collects data from impact sensors and triggers the appropriate protective measures when necessary.
Proper functioning of the airbag control unit is essential, as it forms the heart of the occupant protection system. If it is defective, the airbag warning light illuminates and the protection systems are inoperable.
Why is the Honda Ridgeline YG2 airbag control unit defective?
The Honda Ridgeline YG2 airbag control module often fails because it stores crash data after an accident, triggering a fault condition, or because internal hardware components fail due to aging, power surges, or manufacturing defects. These internal malfunctions cause the module to no longer function properly, necessitating repair.
After an impact, so-called crash data is permanently stored in the airbag control unit. This data can only be deleted through a special repair or a reset.
An internal hardware defect or a memory error can also cause the airbag warning light to stay on. In such cases, a professional diagnosis and specialized repair of the module is essential.
Common error codes for Honda Ridgeline YG2 airbag control unit repair
Typical error codes indicating a defect in the Honda Ridgeline YG2 airbag control unit include internal module errors, communication problems, or problems accessing the crash data log. These specific B-codes indicate that the control unit itself needs to be repaired to restore full functionality to the airbag system.
- B1000 → Control unit communication error → The airbag ECU cannot communicate with other systems.
- B1231 → Internal memory error in the airbag control unit → There is a defect in the internal data memory of the module.
- B1233 → Error accessing crash data memory → Stored crash data blocks the function or cannot be deleted.
- B1240 → Internal module error (hardware defect) → A physical or electronic malfunction in the control unit was detected.
- B1243 → Airbag control unit voltage supply faulty → The module does not receive the correct operating voltage.
- B1610 → Internal Microcontroller Error → The main processor of the control unit has a fault.
- B1615 → EEPROM memory error in the airbag control unit → Problems with the module's non-volatile memory.
What part numbers are available for the Honda Ridgeline YG2 airbag control unit repair?
When repairing a Honda Ridgeline YG2 airbag control module, specific OEM part numbers are critical to ensure compatibility and proper operation. These numbers identify the exact module relevant to your vehicle model, especially for model years 2017 to 2023, enabling a successful repair.
The primary and most common part number for the Honda Ridgeline YG2 airbag control module is 77960-T6Z-A03. This number has been validated for model years from 2017 through at least 2023 and is supplied by Honda or its supplier, Denso.
Additionally, the following OEM replacement numbers are relevant for the Honda Ridgeline YG2 airbag control unit as they offer identical functions and are interchangeable:
- 77960-T6Z-A02
- 77960-T6Z-A01
- 77960T6ZA030M2 (a variant of the main number without hyphens)
These part numbers are for the airbag control unit itself only, not for sensors or other components of the SRS system. They are essential for the precise diagnosis and repair of the airbag module.
Benefits of Honda Ridgeline YG2 Airbag Control Unit Repair
Repairing the Honda Ridgeline YG2 airbag control unit offers significant cost advantages over purchasing a new part and represents a sustainable alternative, as existing hardware is remanufactured. By erasing crash data and correcting internal errors, your original module can be restored to full functionality without compromising safety.
Resetting the airbag control unit after an accident removes the permanently stored crash data and allows the module to be reused. This significantly saves costs compared to purchasing a new control unit.
Professional repairs not only fix the stored errors but can also repair internal hardware defects. This ensures that the repaired module meets strict safety standards once it has been correctly programmed into the vehicle.
Honda Ridgeline YG2 Airbag Control Unit Installation and Compatibility
The Honda Ridgeline YG2 airbag control unit is typically installed centrally under the dashboard or center console and requires professional programming to the vehicle's vehicle identification number (VIN) for successful installation. Compatibility primarily extends to Honda Ridgeline models from 2017 to 2023, with the exact part number being crucial.
Before removing the defective module, the vehicle battery must always be disconnected and all airbag connectors unplugged to prevent accidental airbag deployment. The installation location is often protected and requires precise work.
After repair or replacement, the airbag control unit must be reprogrammed to the specific VIN of the Honda Ridgeline YG2 by a specialist workshop. Without this coding, the system cannot function properly, and the warning light will remain active.
