Airbag control unit with part number 98820-5KW0A

What does the airbag control unit 98820-5KW0A do?

The airbag control unit 98820-5KW0A is the control unit of the restraint system (SRS) in Nissan. It reads the crash sensors, decides in an impact within milliseconds on the triggering of airbags and seatbelt pretensioners, and keeps the system under constant watch. Faults that occur are reported to the airbag warning light.

In normal operation, the unit works in the background and checks sensors, wiring and ignition circuits.

After an accident, it stores crash data and locks itself. The data remains stored in the unit.

Why does the control unit 98820-5KW0A fail?

Stored crash data is the most common cause in the 98820-5KW0A, even if no airbag has deployed. Other causes are aged electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes.

• Aged electronic components
• Cold solder joints
• Moisture and corrosion on plug connections
• Voltage spikes, for example from a weak battery or a jump start

Crash data cannot be erased with an ordinary diagnostic tool. Airbag24 removes it during the repair.

How can you tell that the 98820-5KW0A is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, an error message appears, and the diagnostic tool reaches the control unit no longer. The fault memory cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then not be triggered.

The light is the clearest sign. Check the system promptly if it does not go out.

An error message in the instrument cluster is another sign. Only the read-out shows whether the fault lies in the control unit or in its surroundings.
