Airbag control unit with part number 77960-S9V-A013-C1

What is the function of Airbag Control Unit 77960-S9V-A013-C1?

The control unit with part number 77960-S9V-A013-C1 is the central control module of the SRS (Supplemental Restraint System) in the third-generation Honda Pilot. It processes data from crash sensors and determines whether to deploy airbags and seatbelt pretensioners, thereby protecting occupants during a collision.

As the brain of the passive safety system, this module continuously monitors all connected components, including front, side, and head airbags, seatbelt pretensioners, seat occupancy detection, and external crash sensors. It tracks their status and ensures that the entire system operates flawlessly in an emergency. Its primary task is the rapid and reliable evaluation of accident scenarios to precisely trigger restraint devices.

The part number 77960-S9V-A013-C1 is a verified OEM part for the Honda Pilot. Very similar variants exist, such as 77960-S9V-A013-M1 or 77960-S9V-A512-C1. These belong to the same control unit family but may differ in internal software or vehicle-specific homologation.

Why does control unit 77960-S9V-A013-C1 fail?

The most common cause of failure is the storage of crash data after an accident. For safety reasons, the control unit then locks itself and reports an internal error. Additional faults arise from internal electronic damage, such as defective memory chips, voltage regulators, or corrosion caused by moisture.

Even if no airbags deployed, crash data remains permanently stored in the control unit’s memory after an accident. This record serves to document the event and causes the airbag warning light to illuminate, marking the system as “faulty” or “locked.” Such data cannot be erased using standard workshop diagnostic tools.

Furthermore, hardware defects on the circuit board can also be responsible. Defective SMD components—such as driver ICs, processor parts, or memory chips—lead to internal malfunctions. External factors like moisture damage, resulting in corrosion and broken traces, can likewise impair the control unit’s functionality.

How do you recognize a faulty 77960-S9V-A013-C1?

A defect in control unit 77960-S9V-A013-C1 primarily manifests as the airbag warning light (SRS lamp) remaining constantly illuminated on the instrument panel. Often, error codes such as “Crash data stored” or “Control unit faulty” cannot be cleared, or the unit becomes inaccessible to diagnostic equipment.

The clearest symptom is the persistently lit SRS warning light. It does not turn off after starting the vehicle, indicating a permanent, safety‑critical fault within the system.

During a workshop diagnosis, specific error codes are read out. Entries like “Crash recorded” or codes pointing to an internal control unit fault provide clear evidence. These errors cannot be resolved with a standard diagnostic tester.

In more severe cases—for example, when there is damage to the internal power supply—communication with the control unit via the OBD interface becomes impossible. The module fails to respond to diagnostic requests, making precise fault analysis inside the vehicle extremely difficult.

In which vehicles is control unit 77960-S9V-A013-C1 installed?

The SRS airbag control unit 77960-S9V-A013-C1 is specifically designed for Honda vehicles. At Airbag24, we repair this module for third‑generation Honda Pilot models, including the YF2 and YF4 series as well as facelifted versions, ensuring precise identification and reliable repair.

We offer repair services for this control unit on the following models and series:

How does repair work at Airbag24?

The repair process is designed for efficient and safe restoration of full functionality. After removal by a qualified workshop, the control unit is shipped to Airbag24. Here, electronic refurbishment takes place, including clearing crash data and conducting a final functional test before returning the unit.

First, a thorough diagnosis should be performed at a certified workshop to confirm that the fault lies within the control unit itself, rather than in external components such as sensors or wiring. The removed control unit, typically securely mounted in the center tunnel, is then carefully packaged for transport.

Upon receipt at Airbag24, our technicians conduct an initial inspection and analyze the stored error codes. The core of the repair involves resetting the module, completely erasing any stored crash data. If necessary, additional defective electronic components on the circuit board are repaired or replaced.

Subsequently, the control unit undergoes a final functional test on a specialized test bench to verify correct communication and flawless operation. Following a successful test, the device is prepared for return shipment. We provide 2 years' statutory liability for defects on every repair.
