Airbag control unit with part number 98820-5RX0A

What does the airbag control unit 98820-5RX0A do?

The airbag control unit 98820-5RX0A is the central control unit of the restraint system (SRS) of Nissan. It evaluates the crash sensors, decides in a crash within a very short time whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

If the unit detects a fault, it shows this via the airbag warning light in the instrument cluster. Monitoring therefore also takes place outside of a crash.

After a crash, the unit stores crash data and locks itself.

Why does the control unit 98820-5RX0A fail?

The most common cause of the failure of the 98820-5RX0A is stored crash data after a crash, even if no airbag has deployed. In addition, there are aged components, cold solder joints, moisture and corrosion, and voltage spikes.

Crash data cannot be removed with a normal diagnostic tool. Airbag24, however, deletes it during the repair.

Apart from the crash data, ageing, cold solder joints and moisture on the contacts have an effect. Voltage spikes, for example from a weak battery or a jump start, can also cause a fault. Only the examination shows which of these causes is actually present.

How can you tell that the 98820-5RX0A is defective?

A defect in the 98820-5RX0A shows itself through the airbag warning light in the instrument cluster, which stays on permanently or intermittently. In addition, an error message appears, the diagnostic tool finds no connection to the control unit, and the fault memory cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may then fail to deploy, even if the vehicle appears unremarkable in everyday use. The signs indicate a defect but do not clarify the cause. For that, the fault memory must be read out.
