Airbag control unit with part number 98820-9PB0A

What does the airbag control unit 98820-9PB0A do?

The airbag control unit 98820-9PB0A manages the SRS restraint system of Nissan. In a crash, it determines within fractions of a second which airbags and seatbelt pretensioners fire, and it monitors the system continuously.

The system reports faults to the driver via the airbag warning light on the instrument cluster.

If an accident occurs, the unit stores crash data and locks itself.

Why does the control unit 98820-9PB0A fail?

The most common cause of a failure in the 98820-9PB0A is crash data stored after an accident, even if no airbag has deployed; a normal diagnostic tool does not erase them. Also considered are ageing electronic components, cold solder joints, moisture and corrosion at connectors, and voltage spikes.

Crash data arise from the event itself and remain in the unit afterwards.

The other causes tend to act gradually: components age, solder joints lose contact, moisture and corrosion attack connectors, and voltage spikes, for example from a weak battery or jump-starting, strain the electronics.

How can you tell that the 98820-9PB0A is defective?

A defect in the 98820-9PB0A shows up in the airbag warning light, which lights up permanently or only intermittently, in an error message on the instrument cluster, or in the diagnostic tool failing to connect to the control unit. A fault memory that cannot be cleared is a further sign.

The warning light is the unit's feedback to you. The individual signs at a glance:

• Airbag warning light is lit permanently
• Airbag warning light is lit only intermittently
• Error message on the instrument cluster
• Diagnostic tool receives no connection to the control unit
• Fault memory cannot be cleared

In the event of a defect, the airbags and seatbelt pretensioners may not trigger in an emergency, so you should take the signs seriously.
