Airbag control unit with part number 98820BV90A

What is the function of the airbag control unit 98820BV90A?

The airbag control unit with part number 98820BV90A is the central control module for the passive safety system (SRS) in the Nissan Juke F15 (2010–2019). It is manufactured by Bosch (reference 0285012139) and is responsible for processing data from impact sensors and, in the event of a collision, precisely triggering the airbags and seatbelt pretensioners.

As the heart of the Supplemental Restraint System (SRS), this control unit continuously monitors all connected components, including the various crash sensors distributed throughout the vehicle, as well as the ignition pyrotechnic devices of the airbags and seatbelt pretensioners.

Under normal operating conditions, the unit ensures system readiness and reports malfunctions via the SRS warning light. In the event of an accident, the logic embedded in the control unit determines within milliseconds which restraint systems must be activated to provide optimal protection for occupants.

Why does the control unit 98820BV90A fail?

The most common cause of failure for the control unit 98820BV90A is the storage of crash data after an accident, which effectively locks the device. Other causes include electronic faults due to moisture, water damage, or internal component defects. Physical damage to wiring or connectors can also lead to failure.

Following an airbag deployment, a permanent fault record—known as crash data—is stored in the control unit’s memory. This entry acts as a kind of black box but simultaneously prevents further operation of the unit to avoid unintended re‑activation. The unit must then be professionally reset.

In addition to accident‑related lockouts, environmental factors such as penetrating moisture can cause corrosion on the circuit board and short circuits. Electronic disturbances, for example from voltage fluctuations in the vehicle’s electrical system, or age‑related wear of internal components are also well‑known sources of failure.

How do you recognize a defect in the 98820BV90A?

A defect in the control unit 98820BV90A typically manifests as a permanently illuminated or flashing airbag warning light (SRS warning lamp) in the instrument cluster. Often, communication with the control unit via an OBD diagnostic tool is no longer possible, or error messages such as “Airbags defective” appear on the display.

The primary and unmistakable sign is the activated SRS warning light, indicating a malfunction in the restraint system and suggesting that the airbags may not deploy in the event of another accident.

In the workshop, the defect often becomes apparent when the fault memory cannot be read. Diagnostic tools receive no response from the control unit, pointing to either a complete loss of communication or an internal fault. The fault memory typically displays “No communication with the airbag control unit.”

Rarely, specific messages may also appear on the vehicle’s display, such as “Airbags defective” or even “Fuel shut-off valve,” signaling an issue within the SRS. In any case, immediate inspection at a specialized workshop is essential, as occupant safety can no longer be guaranteed.

In which vehicles is the 98820BV90A installed?

The airbag control unit with part number 98820BV90A and its associated Bosch reference 0285012139 is specifically designed for Nissan models. It is primarily used in the first-generation Nissan Juke (model F15), produced between 2010 and 2019.

At Airbag24, we repair this control unit for the following vehicle model:

Nissan Juke F15 (model years 2010–2019)

Accurate identification always relies on the part number printed directly on the control unit. It is crucial that the number 98820BV90A or the compatible manufacturer’s number 0285012139 match to ensure compatibility.

How does the repair of the 98820BV90A proceed at Airbag24?

Repair at Airbag24 begins with the submission of the removed control unit. Following a thorough incoming inspection, stored crash data is erased, and any electronic defects at the component level are rectified. Finally, a functional test is performed before the refurbished unit is returned with a 12‑month warranty.

As a first step, it is recommended to read the vehicle’s fault memory to pinpoint the exact nature of the defect. After professional removal, the control unit is securely packaged and shipped to Airbag24.

Our technicians conduct a systematic analysis to identify the precise cause of the failure, including checks for moisture damage, short circuits, and evaluation of the internal memory for crash data.

The actual repair focuses on eliminating the identified faults. Stored crash data is professionally erased, and defective electronic components are replaced. Following successful restoration and a final test, the control unit is fully functional again and ready for installation.
