Airbag control unit with part number 98820-9PD0A

What does the airbag control unit 98820-9PD0A do?

The airbag control unit 98820-9PD0A coordinates the SRS system of Nissan. It processes the readings from the crash sensors, selects the appropriate airbags and seatbelt pretensioners in a collision and triggers them within milliseconds. At the same time it monitors all components and displays faults via the airbag warning light.

The control unit runs continuously, even though you may not notice anything while driving. It checks the power supply, wiring and sensors, and stores any faults it finds in memory.

If an accident has occurred, the unit secures crash data and locks itself afterwards.

Why does the control unit 98820-9PD0A fail?

With the 98820-9PD0A, the most common cause of failure is crash data stored after an accident, even if no airbag has deployed; a standard diagnostic tool does not remove them. Other causes to consider are aged electronic components, cold solder joints, moisture and corrosion at connectors, and voltage spikes, for example from a weak battery or a jump start.

Nothing can be seen from the outside; the cause only shows up in the fault memory.

Connectors deserve particular attention, because moisture and corrosion gradually change the contact.

How can you tell that the 98820-9PD0A is defective?

A defect on the 98820-9PD0A shows itself through an airbag warning light in the instrument cluster that lights up permanently or intermittently, a fault message in the display, no connection to the diagnostic tool, and a fault memory that cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

The signs in detail:

• Airbag warning light on permanently
• Airbag warning light on only intermittently
• Fault message in the instrument cluster
• Diagnostic tool cannot find the control unit
• Fault memory cannot be cleared

Take any of these indications seriously, even if the vehicle drives normally.
