Airbag control unit with part number 98820-3PU0A

What does the airbag control unit 98820-3PU0A do?

The airbag control unit 98820-3PU0A coordinates the restraint system (SRS) of Nissan. It evaluates the signals from the crash sensors and decides within milliseconds, in the event of an accident, which airbags and seatbelt pretensioners to trigger. It indicates faults via the airbag warning light.

The unit monitors the entire system continuously: sensors, wiring and supply voltage are checked constantly, so that faults are noticed early.

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

Why does the control unit 98820-3PU0A fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed; a normal diagnostic tool cannot erase it. Other possible causes include aged components, moisture and corrosion on plug connectors, and voltage spikes.

At Airbag24, the crash data is erased during the repair. The other causes at a glance:

• aged electronic components
• cold solder joints on the circuit board
• moisture and corrosion on plug connectors
• voltage spikes, for example from a weak battery or a jump start

How can you tell that the 98820-3PU0A is defective?

A defect shows when the airbag warning light in the instrument cluster lights up permanently or intermittently, an error message appears, the diagnostic tool cannot establish a connection to the control unit, or the fault memory cannot be cleared. In this case, airbags and seatbelt pretensioners may not be able to deploy in an emergency.

The warning light is the most important sign, because it shows the fault directly as soon as the system detects it. If it stays on permanently after the ignition is switched on, have the fault memory read out promptly.

A missing connection to the diagnostic tool is also a clear sign that something in the system is wrong.
