Airbag control unit with part number 98820-5RA0C

What does the airbag control unit 98820-5RA0C do?

The airbag control unit 98820-5RA0C manages the restraint system (SRS) in Nissan. In an accident, it evaluates the signals from the crash sensors and decides within milliseconds which airbags and seatbelt pretensioners are triggered.

It also monitors all components of the system continuously. Faults that are found are output via the airbag warning light in the instrument cluster.

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

Why does the control unit 98820-5RA0C fail?

The most common reason for a failure of the 98820-5RA0C is stored crash data after an accident, even if no airbag was deployed. A normal diagnostic tool cannot erase this data. Aged components, cold solder joints, moisture and corrosion, and voltage spikes are also possible.

Aged electronics lose reliability over time. Cold solder joints and corrosion at plug connections disrupt the signal flow, which can cause faults in the system.

Voltage spikes, for example from a weak battery or when a jump start is connected, also affect the electronics.

How can you tell that the 98820-5RA0C is defective?

The airbag warning light in the instrument cluster indicates a defect in the 98820-5RA0C by staying on permanently or intermittently. In addition, fault messages appear in the instrument cluster, and the diagnostic tool finds no contact with the control unit.

• Warning light on permanently or intermittently
• Fault message in the instrument cluster
• No connection between the diagnostic tool and the control unit
• Fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may not be able to deploy in such a fault.
