What is a Honda Pilot YF4 airbag control unit?
The Honda Pilot YF4 airbag control unit is the central safety unit that activates all occupant restraint systems in the event of a crash. It precisely monitors impact sensors, as well as belt and seat occupancy sensors, stores important crash data, and ensures the immediate and proper deployment of all connected airbag modules in the vehicle to ensure maximum occupant safety.
This module, also known as the SRS Airbag Computer Diagnostic Control Module, is a critical component of the Supplemental Restraint System. It processes real-time data from various sensors in the vehicle as soon as the drive mode ("Power ON") is activated.
In addition, the control unit records important event data, which is essential for detailed diagnostics after an accident or in the event of system malfunctions. It is coded for each vehicle and is matched to the vehicle identification number (VIN).
Why is the Honda Pilot YF4 airbag control unit defective?
A Honda Pilot YF4 airbag control unit can be defective if there are internal memory errors, crash data is permanently stored after an accident, or there are power supply issues. These defects typically cause the airbag warning light to illuminate, severely impairing the functionality of the safety system. Repair or replacement is urgently required to restore safety.
If a vehicle is involved in an accident, the airbag control unit permanently stores this crash data, even if the airbags weren't deployed. This often prevents the system from functioning again.
Internal electronic defects or damage caused by excessive voltage are also common causes of failure. In such cases, a professional Honda Pilot YF4 airbag control unit repair or replacement is essential.
Common error codes for Honda Pilot YF4 airbag control unit repair
Common error codes for Honda Pilot YF4 airbag control unit repairs indicate internal problems with the SRS module. These include B0001 (internal control unit error), B0002 (memory error), as well as Honda-specific codes such as 6-7 (frequent voltage problems), 87-31, and 91-1x, all of which indicate defects in the control unit itself and require precise diagnosis.
- B0001 → Internal error in the airbag control unit (SRS ECU) → Airbag ECU
- B0002 → Memory error or unreadable memory in the airbag control unit → Airbag ECU
- 6-7 → Internal error in the SRS control unit, often check voltage problem → Airbag ECU (Honda specific)
- 87-31 → Internal error of the SRS control unit → Airbag ECU (Honda Codes)
- 91-1x → Internal error of the SRS control unit (x stands for subcodes) → Airbag ECU (Honda Codes)
These error codes indicate specific problems with the airbag control module that require professional Honda Pilot YF4 airbag control module repair or reset. They relate exclusively to the control module and exclude other airbag components.
For an accurate diagnosis and to clear the airbag warning light, professional diagnostic tools are required. This ensures the restoration of full functionality of the SRS system and eliminates safety risks.
What part numbers are available for the Honda Pilot YF4 airbag control unit repair?
Specific original OEM part numbers exist for the Honda Pilot YF4 airbag control unit repair, ensuring exact compatibility with the 2009 to 2015 vehicle series. The only verified part numbers for this airbag control unit are 77960-S9V-A720-M1 and 77960-S9V-A013-C1. These must be calibrated and programmed with the vehicle system after installation.
These OEM part numbers are intended exclusively for the airbag control unit of the second-generation Honda Pilot (YF4). These are genuine Honda parts, not replicas or generic replacement parts.
It is crucial that only the exact, correct OEM part numbers are used in a Honda Pilot YF4 airbag control unit repair . An incorrect part number can lead to incompatibilities and safety risks, as the module is tailored to the specific vehicle.
The modules are not delivered pre-programmed. Therefore, after installation, programming and calibration using the vehicle's vehicle identification number (VIN) by a specialist workshop is mandatory to ensure full functionality.
