Airbag control unit with part number 98820-5RJ0A

What does the airbag control unit 98820-5RJ0A do?

The airbag control unit 98820-5RJ0A evaluates the sensor data of the restraint system (SRS) at Nissan. In an accident it selects within milliseconds which airbags and seatbelt pretensioners fire, and it monitors all components continuously. After an accident, it stores crash data and locks itself.

The unit detects faults itself and shows them via the airbag warning light in the instrument cluster.

Why does the control unit 98820-5RJ0A fail?

The most common cause is crash data from an accident, even if no airbag has deployed. Added to this are ageing electronics, moisture at plugs, cold solder joints and voltage spikes at the 98820-5RJ0A.

Crash data cannot be deleted with a normal diagnostic tool. The other causes lie more in the hardware of the unit and in the external connections.

These causes also come into consideration:

• Components that wear out over the years
• Solder joints with a cold fault
• Wetness and rust on the plugs
• Current spikes when starting or with a weak battery

How can you tell that the 98820-5RJ0A is defective?

The airbag warning light lights up permanently or intermittently, an error message appears in the instrument cluster, or the diagnostic tool cannot reach the control unit 98820-5RJ0A. A fault memory that cannot be cleared also indicates a defect. In this case, airbags and seatbelt pretensioners may fail to deploy in an emergency.

Above all, the light deserves attention. If it stays on after starting, have the fault memory read out. Only this result shows what the cause is.
