Airbag control unit with part number 8917006670

What is the function of the airbag control unit 8917006670?

The airbag control unit with part number 8917006670 is the central control unit for the restraint system in the Toyota Camry XV50. It continuously monitors the vehicle’s sensors, processes their data, and, in the event of a crash, ensures the precise deployment of airbags and seatbelt pretensioners.

As an original electronic component for the Toyota Camry of the XV50 series (model years 2011–2019), this control unit acts as the brain of the safety system. It communicates constantly via the vehicle bus with other systems, ensuring operational readiness.

The unit is also known under the alternative OEM numbers 8917006770 and 150800-2310. Proper functionality is critical, as without a fully functional control unit, the passive safety systems will not activate in an emergency.

Why does the control unit 8917006670 fail?

The most common cause of failure for control unit 8917006670 is the storage of crash data after an accident, which prevents further use. Additional defects arise from moisture, age-related wear of electronic components, or severe vibrations that lead to internal hardware malfunctions.

After an airbag deployment, a permanent entry is stored in the control unit’s memory—known as the “crash lock.” This entry cannot be erased using standard diagnostic tools, making professional repair or replacement unavoidable.

In addition to crash data, hardware failures are also frequent. Moisture can cause corrosion on the circuit board, while aging of components such as capacitors or sensors may result in malfunctions or complete communication failure.

How do you recognize a defect in 8917006670?

A defect in the airbag control unit 8917006670 primarily manifests as a permanently illuminated airbag warning light. Often, communication with the control unit via a diagnostic tool becomes impossible, or specific fault codes such as B1920 are recorded.

The clearest indication is the airbag warning lamp. Typically, it illuminates immediately after starting the engine and remains lit, unlike in a functioning system. In some cases, the light appears only sporadically.

Another clear symptom is when the workshop cannot access the airbag system’s fault memory. The diagnostic tool then reports “No communication” or “Control unit not responding,” indicating a serious internal fault.

Stored fault codes are also an indicator. A specific code like B1920, which points to a short circuit in the passenger-side airbag circuit, may directly indicate a defect within the control unit itself—even if the airbag remains intact.

In which vehicles is the control unit 8917006670 installed?

The airbag control unit with part number 8917006670, along with the alternative numbers 8917006770 and 150800-2310, is specifically designed for the Toyota Camry. It was installed in a particular generation of this model.
