Airbag control unit with part number 98820-6UT0A

What does the airbag control unit 98820-6UT0A do?

The airbag control unit 98820-6UT0A controls the restraint system (SRS) of Nissan as a central unit. It reads the values from the crash sensors, decides in an accident within milliseconds whether airbags and seatbelt pretensioners are triggered, and checks the system continuously.

If the unit detects a fault, it shows this via the airbag warning light in the instrument cluster.

After an accident it stores crash data and locks itself.

Why does the control unit 98820-6UT0A fail?

The most common cause is that crash data remains in the unit after an accident, even if no airbag has been triggered. Other causes are aged components, moisture and corrosion at plug connections, and voltage spikes.

Such crash data cannot be removed with an ordinary diagnostic tool. Other causes include, among others:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or jump-starting

Which of these is present only becomes clear during the inspection on the test bench.

How can you tell that the 98820-6UT0A is defective?

A defect shows itself through the airbag warning light, through an error message in the instrument cluster, and through a diagnostic tool that cannot make a connection.

• airbag warning light stays on constantly or intermittently
• error message in the instrument cluster
• no connection between diagnostic tool and control unit
• fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may then possibly fail to trigger. Therefore have the system checked promptly rather than ignoring the warning light.
