Airbag control unit with part number 98820-EZ00A

What does the airbag control unit 98820-EZ00A do?

The airbag control unit 98820-EZ00A is the central component of the SRS restraint system for Nissan. It receives the signals from the crash sensors, calculates in an accident within milliseconds which airbags and seatbelt pretensioners trigger, and controls the system during operation.

The unit reports faults via the airbag warning light. If an accident has occurred, it stores crash data and locks itself afterwards.

In normal operation the monitoring goes unnoticed, because it runs in the background.

Why does the control unit 98820-EZ00A fail?

The most common cause in the 98820-EZ00A is crash data stored after an accident, even if no airbag was triggered. Further causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

An ordinary diagnostic tool does not erase this data. Airbag24 erases it during the repair.

Components age, solder joints can go cold, and moisture or corrosion affects the contacts at the plugs. Weak batteries and jump-starting can cause voltage spikes that also stress the electronics.

How can you tell that the 98820-EZ00A is defective?

An airbag warning light that stays on permanently or intermittently is the most important sign of a defect on the 98820-EZ00A. Typical are also an error message in the instrument cluster and a missing connection to the diagnostic tool.

• Airbag warning light in the instrument cluster stays on permanently or intermittently
• Error message in the instrument cluster
• Diagnostic tool establishes no connection to the control unit
• Fault memory cannot be cleared

In such a defect, airbags and seatbelt pretensioners may not be triggered in an emergency. Take the warning light seriously and have it checked promptly, even if the car otherwise runs normally.
