Airbag control unit with part number 0 285 001 613

What is the function of Airbag Control Unit 285001613?

The Airbag Control Unit 285001613, also known as the SRS Control Unit, is the central control module for the passive safety system in the Toyota Proace X70 (2013–2016). It continuously monitors all relevant sensors and, in the event of a crash, deploys the airbags and activates the seatbelt pretensioners to protect occupants.

As the brain of the Supplemental Restraint System (SRS), this module collects and processes real-time data from acceleration and crash sensors distributed throughout the vehicle. Based on this information, it makes the critical decision about whether and which restraint systems need to be activated.

Therefore, the proper functioning of this control unit is essential for driver safety. A failure or malfunction will result in the deactivation of the entire airbag system.

Why does Control Unit 285001613 fail?

The most common cause of failure for Control Unit 285001613 is the storage of crash data after an airbag deployment. Other causes include electronic faults such as broken wiring, faulty connectors, or internal sensor malfunctions. This unit is also known by part numbers 89170-04J30, 89170-04J31, 89170-04J32, and 7701056324.

After a crash in which the airbags have deployed, the control unit permanently writes the crash data into its internal memory. This lockout is a manufacturer‑imposed safety feature that prevents the reuse of a potentially damaged unit. Professional repair can remove this lockout.

In addition, hardware defects may occur even without a crash. These include issues with the internal power supply, defective solder joints at connector contacts, or failure of electronic components on the circuit board. It’s important to note that the part number listed here is compatible with references 89170-04J30, 89170-04J31, 89170-04J32, as well as 7701056324, all referring to the same component.

In some cases, the root cause lies not in the control unit itself but in the vehicle environment. Damaged cables, faulty seat occupancy mats, or malfunctioning crash sensors can also trigger error messages. A thorough diagnosis at a workshop is therefore essential before removing the control unit.

How do you recognize a defect in Control Unit 285001613?

A defective Airbag Control Unit 285001613 primarily manifests as a constantly illuminated or flashing SRS warning light on the instrument panel. Often, communication with a diagnostic tool becomes impossible, or stored fault codes—especially after a crash—cannot be cleared. This indicates a deactivated airbag system.

The most obvious sign is the airbag warning light (SRS light) that fails to turn off after the engine starts. This alerts the driver that the restraint system is not operational and would not deploy in the event of a crash.

An additional clear symptom appears during vehicle diagnostics: if the control unit no longer responds to requests from a diagnostic device, it points to a serious internal fault. Likewise, the inability to clear fault codes such as “Crash Data Stored” or “Internal Control Unit Error” suggests a defect requiring repair.

In which vehicles is Control Unit 285001613 installed?

The Airbag Control Unit with part number 285001613, along with its equivalent variants 89170-04J30 or 7701056324, is specifically designed for the Toyota Proace of the X70 series. At Airbag24, we specialize in repairing this control unit for vehicles manufactured between 2013 and 2016.

Toyota Proace X70 (model years 2013–2016)

How does repair work at Airbag24?

Upon receiving the removed Control Unit 285001613 at Airbag24, a professional electronic refurbishment takes place. Stored crash data is erased, and any defective electronic components on the circuit board are replaced with new ones. Final tests confirm full functionality, followed by 2 years’ statutory liability for defects.

The process ideally begins with a diagnosis at your local workshop to rule out external sources of failure. Once it’s confirmed that the control unit is defective, it’s carefully removed and sent to us together with the repair order.

Upon arrival at Airbag24, our technicians perform an initial inspection. The unit is then opened to analyze its electronics. Stored crash data is deleted from the memory chip, and all components identified as defective are expertly replaced. After refurbishment, we simulate the vehicle environment on a test bench to ensure proper operation.

The repaired control unit is ready for immediate use once reinstalled in the vehicle. We provide 2 years' statutory liability for defects on every repair.

Is Repairing 285001613 Worth It?

Repairing the airbag control unit 285001613 is an economically sensible alternative to the costly purchase of a new part. Not only do you save significantly, but you also receive a refurbished original component. This avoids potential compatibility issues and ensures the full functionality of the safety system, backed by 2 years’ statutory liability for defects.

A new control unit from the manufacturer often comes with high costs. In contrast, repair is considerably more affordable and provides a fully functional solution. Since the original unit is restored, you eliminate concerns about vehicle compatibility or the need for time-consuming reprogramming.

Moreover, repair is a sustainable approach, conserving valuable electronic resources and reducing e-waste. With 2 years' statutory liability for defects, you take no risks.
