Airbag control unit with part number 98820-9PG4A

What does the airbag control unit 98820-9PG4A do?

The airbag control unit 98820-9PG4A is the central control unit of the restraint system (SRS) for Nissan. It evaluates the signals of the crash sensors and decides in the event of an accident, within milliseconds, which airbags and seatbelt pretensioners trigger. It also monitors the system continuously and reports faults via the airbag warning light.

While driving, the unit continuously checks whether sensors, wiring and control are in order.

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

Why does the control unit 98820-9PG4A fail?

The most common cause with the 98820-9PG4A is crash data stored after an accident, even if no airbag was triggered. Other causes are aged electronic components, cold solder joints, moisture, corrosion at plug connections and voltage spikes.

A normal diagnostic tool cannot erase this crash data. Airbag24 erases it during the repair. Voltage spikes occur, for example, with a weak battery or when jump-starting.

How can you tell that the 98820-9PG4A is defective?

The airbag warning light in the instrument cluster lights up on the 98820-9PG4A permanently or intermittently. In addition, a fault message appears in the instrument cluster, the diagnostic tool receives no connection to the control unit, and the fault memory cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may then fail to trigger. The warning should therefore be clarified promptly.
