Airbag control unit with part number 98820-9PC0A

What does the airbag control unit 98820-9PC0A do?

The airbag control unit 98820-9PC0A controls the restraint system (SRS) in Nissan. It checks the signals from the crash sensors and fires the appropriate airbags and seatbelt pretensioners within fractions of a second in a crash. It also monitors all components continuously and reports faults via the airbag warning light.

After an accident, it stores crash data in its memory and locks itself.

While driving, the electronics work unnoticed in the background and only become visible when there is a fault.

Why does the control unit 98820-9PC0A fail?

Stored crash data from an accident is the most common cause with the 98820-9PC0A, even without a deployed airbag, and an ordinary diagnostic tool cannot erase it. Aged electronics, cold solder joints, moisture at plug connections and voltage spikes can also lead to failure.

The crash data remains until Airbag24 removes it during the repair. A normal diagnostic tool is not sufficient for this.

For the other causes, ageing, moisture and corrosion at the connections, as well as voltage spikes, play a role, for example from a weak battery or jump-starting.

How can you tell that the 98820-9PC0A is defective?

A fault in the 98820-9PC0A shows through the airbag warning light in the instrument cluster, which lights up permanently or intermittently. Added to this are an error message in the instrument cluster, no connection for the diagnostic tool and a fault memory that cannot be cleared.

Typical signs are:

• the airbag warning light, permanently or intermittently
• error messages in the instrument cluster
• no connection to the control unit when reading out
• a fault memory that cannot be cleared

In an emergency, airbags and seatbelt pretensioners may not be able to deploy. Please have the system checked promptly as soon as any of these signs appears.

Comparing the part number on the label of the removed unit with this page only shows that you have the right unit. The actual cause is only clarified by reading out the fault memory, because it shows whether the control unit itself is defective or whether a plug or cable is the problem. So have it read out beforehand.
