Airbag control unit with part number 98820-9FF0A

What does the airbag control unit 98820-9FF0A do?

The airbag control unit 98820-9FF0A is a central component of the restraint system (SRS) in Nissan. It evaluates crash sensors, determines in an accident which restraint devices are triggered, and monitors the state of the system.

If it detects a fault, it shows this via the airbag warning light. After an accident it also stores crash data and locks itself.

Monitoring runs constantly, even when nothing noticeable happens in everyday driving.

Why does the control unit 98820-9FF0A fail?

The 98820-9FF0A can fail because of an entry from stored crash data, even if no airbag was triggered. A standard diagnostic tool cannot erase this data.

Other causes at a glance:

• ageing of individual electronic components
• poorly made soldered connections
• moisture and rust on plugs
• voltage surges from a weak battery or a jump start

How can you tell that the 98820-9FF0A is defective?

A defect on the 98820-9FF0A may show up on the airbag warning light and as fault messages in the vehicle.

Possible signs include:

• airbag warning light that stays on permanently or only flashes now and then
• fault message in the instrument cluster
• diagnostic tool has no connection to the control unit
• fault memory that cannot be emptied despite an attempt to clear it

In such cases, the airbags and seatbelt pretensioners may fail to trigger in an emergency. A prompt check will provide clarity.
