Airbag control unit with part number 98820-9PD2A

What does the airbag control unit 98820-9PD2A do?

The airbag control unit 98820-9PD2A coordinates the restraint system (SRS) on Nissan. It measures deceleration via the crash sensors, decides in an accident within milliseconds on the airbags and seatbelt pretensioners, and shows faults via the airbag warning light. After an accident it stores crash data and locks itself.

During operation it continuously checks its circuits and the connected components.

It intervenes only in the restraint system and has no function in steering or drive.

Why does the control unit 98820-9PD2A fail?

The most common cause is stored crash data, even if no airbag fired in the accident; a normal diagnostic tool cannot erase them. The other causes include aged electronic components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes from a weak battery or a jump start.

An entry is created already at the event, not only when an airbag fires.

Older components become more susceptible, solder joints can go cold, and moisture with corrosion damages plug contacts.

Voltage spikes from a weak battery or a jump start additionally stress the electronics.

How can you tell that the 98820-9PD2A is defective?

A defective control unit shows itself mainly through the airbag warning light in the instrument cluster, through fault messages and through a failed diagnosis. In an emergency, the airbags and seatbelt pretensioners may then possibly not fire.

In detail, these signs stand out:

• The airbag warning light in the instrument cluster stays on permanently or lights up intermittently.
• A fault message appears in the instrument cluster.
• The diagnostic tool cannot establish a connection to the control unit.
• The fault memory cannot be cleared.

Even a single one of these signs justifies a check.
