Airbag control unit with part number 98820-ZX00E

What does the airbag control unit 98820-ZX00E do?

The airbag control unit 98820-ZX00E is responsible in the restraint system of Nissan for which airbags and seatbelt pretensioners trigger in an accident. To do this, it processes the crash sensors and monitors the system continuously.

It indicates faults via the airbag warning light. After an accident, the unit stores crash data and then locks itself.

Why does the control unit 98820-ZX00E fail?

Stored crash data from an accident is the most common cause in the 98820-ZX00E, even if no airbag has triggered. Standard diagnostic tools cannot erase this data. Further causes are aged components, dry solder joints, moisture and corrosion, and voltage spikes.

During the repair, Airbag24 erases the crash data. The other causes are checked on the test bench.

How can you tell that the 98820-ZX00E is defective?

A defective 98820-ZX00E mainly reveals itself through the airbag warning light in the instrument cluster. These signs also appear:

• error message in the instrument cluster
• diagnostic tool receives no connection to the control unit
• fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may then not trigger. A prompt check is therefore worthwhile.
