Airbag control unit with part number 98820-4DS0A

What does the airbag control unit 98820-4DS0A do?

The airbag control unit 98820-4DS0A forms the central control of the restraint system (SRS) at Nissan. It analyses the signals from the crash sensors, decides on airbags and seatbelt pretensioners in an accident, and monitors the system continuously. It reports irregularities to the airbag warning light.

Self-monitoring covers the wiring, the sensors and the output stages.

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

Why does the control unit 98820-4DS0A fail?

The most common cause is stored crash data after an accident, even if no airbag has fired; a standard diagnostic tool cannot erase it. Other causes in brief: aged electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

In overview, these influences take effect:

• Stored crash data that cannot be erased with a standard diagnostic tool
• Aged electronic components
• Cold solder joints
• Moisture and corrosion at plug connections
• Voltage spikes, for example from a weak battery or jump-starting

Which cause applies only becomes clear after the check.

How can you tell that the 98820-4DS0A is defective?

A defect shows itself when the airbag warning light lights up intermittently or permanently, an error message appears in the instrument cluster, the diagnostic tool cannot establish a connection, or the fault memory cannot be erased.

These signs are typical:

• Warning light in the instrument cluster lights up
• Error message is displayed
• Diagnostic tool does not connect to the control unit
• Fault memory persists

In an emergency, airbags and seatbelt pretensioners may then fail to deploy. For this reason, have the warning checked promptly.
