Airbag control unit with part number 98820-9FW3A

What does the airbag control unit 98820-9FW3A do?

The airbag control unit 98820-9FW3A is the central control unit of the restraint system (SRS) for Nissan. It evaluates the signals from the crash sensors, decides in an emergency within milliseconds which airbags and seatbelt pretensioners to trigger, and reports faults via the airbag warning light. After an accident it stores crash data and locks itself.

The unit works in the background and checks the entire system. Deviations end up in the fault memory, which can be read out with a diagnostic tool.

The lock is only lifted by the repair.

Why does the control unit 98820-9FW3A fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered. Further causes at a glance:

In an emergency, airbags and seatbelt pretensioners may then fail to trigger. Such a finding should therefore be checked promptly.
