Airbag control unit with part number 98820-1TV0A

What does the airbag control unit 98820-1TV0A do?

The airbag control unit 98820-1TV0A controls the restraint system (SRS) for Nissan. It evaluates the signals from the crash sensors and, in an accident, decides within milliseconds which airbags and seatbelt pretensioners are triggered. It reports faults in the system via the airbag warning light.

During operation, the unit monitors the system components without interruption. It checks connections, supply and trigger stages and records irregularities in the fault memory.

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

Why does the control unit 98820-1TV0A fail?

The most common cause is crash data that remains stored after an accident, even when no airbag has deployed. A standard diagnostic tool cannot erase this data. Further causes are aged electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

The other causes at a glance:

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

How can you tell that the 98820-1TV0A is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and a fault message appears in the instrument cluster. In addition, the diagnostic tool cannot reach the control unit or the fault memory cannot be erased. In an emergency, the airbags and seatbelt pretensioners may then fail to deploy.

These signs appear in practice in the following forms:

• Warning light on permanently
• Warning light on intermittently
• Fault message in the instrument cluster
• Diagnostic tool cannot reach the control unit
• Fault memory cannot be erased

The light is the system's direct display and therefore the most important warning sign. Have the restraint system checked promptly for any of these signs.
