Airbag control unit with part number 98820-9PA0A

What does the airbag control unit 98820-9PA0A do?

The 98820-9PA0A is the central control unit of the SRS restraint system of Nissan. It checks the crash sensors, determines which airbags and seatbelt pretensioners are to be triggered in an accident, and reports faults via the airbag warning light.

The system is in continuous operation. An accident leaves crash data in the unit, and the control unit is then locked.

Why does the control unit 98820-9PA0A fail?

With the 98820-9PA0A, stored crash data are the most common cause, even when no airbag has triggered. A normal diagnostic tool cannot erase them. Aged components, moisture and voltage spikes can also cause the failure.

In addition, these influences come into question:

• electronic components that wear out over time
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or jump-starting

How can you tell that the 98820-9PA0A is defective?

A defect in the 98820-9PA0A shows up as the airbag warning light in the instrument cluster lighting up constantly or intermittently, and as error messages that appear there.

These signs indicate a defect:

• The airbag warning light stays on.
• The airbag warning light only comes on intermittently.
• The fault memory cannot be erased.
• The diagnostic tool does not find the control unit.

In an emergency, the airbags and seatbelt pretensioners may then not trigger. A check is therefore worthwhile without delay.
