Airbag control unit with part number 98820-6WK1C

What does the airbag control unit 98820-6WK1C do?

The airbag control unit 98820-6WK1C coordinates the restraint system (SRS) of Nissan. It evaluates the sensor signals, decides in an accident within milliseconds on the triggering of airbags and seatbelt pretensioners, and reports faults via the airbag warning light.

While driving it monitors the entire system continuously. After an accident it stores crash data and locks itself.

Why does the control unit 98820-6WK1C fail?

The most common cause is crash data stored after an accident, which a normal diagnostic tool does not remove. In addition there is age-related damage to the electronics and corrosion at plug connectors, along with voltage spikes from the battery or jump-starting.

After an accident the unit stores crash data, even when no airbag has triggered. The data stays in the control unit until Airbag24 clears it during the repair.

Electronic components age, and solder joints can go cold over time.

Moisture and corrosion at plug connections disturb the contact. Voltage spikes occur, for example, with a weak battery or when starting with a jump-start.

How can you tell that the 98820-6WK1C is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently. Accompanying this may be an error message in the instrument cluster, no contact with the diagnostic tool, and a fault memory that cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may therefore fail to trigger. The light thus indicates the defect and must be checked promptly.
