Airbag control unit with part number 98820-9GK2C

What does the airbag control unit 98820-9GK2C do?

The airbag control unit 98820-9GK2C is the central control unit of the restraint system (SRS) in Nissan. It evaluates the crash sensors, decides within milliseconds in a crash on the triggering of airbags and seatbelt pretensioners, and monitors the system continuously.

The unit indicates faults via the airbag warning light. After a crash it stores crash data and locks itself.

In everyday use the control unit runs without any visible action on your part, until a fault occurs.

Why does the control unit 98820-9GK2C fail?

The most common cause is crash data stored after an accident, even without an airbag having triggered. Further causes are aged electronic components, dry joints, moisture and corrosion on plug connectors, and voltage spikes, for example from a weak battery or jump-starting.

Crash data cannot be removed with a usual diagnostic tool. Airbag24 therefore removes them during the repair.

The other causes concern the electronics, the contacts and the power supply. Which of them applies is shown by the examination on the test bench.

How can you tell that the 98820-9GK2C is defective?

A defect shows up as the airbag warning light, which lights up permanently or intermittently, as an error message in the instrument cluster, as a lack of connection to the diagnostic tool and as a fault memory that cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then not trigger.

The airbag warning light in the instrument cluster lights up permanently or intermittently. It thus shows the state of the system.

If the diagnostic tool cannot connect to the control unit, or the fault memory cannot be cleared, there is a fault that must be checked.
