Airbag control unit with part number 98820-5KX0A

What does the airbag control unit 98820-5KX0A do?

The airbag control unit 98820-5KX0A is the central control unit of the restraint system (SRS) for Nissan. Within milliseconds in an accident, it decides which airbags and seatbelt pretensioners are triggered.

It evaluates the signals from the crash sensors. At the same time, it monitors the system continuously and reports faults via the airbag warning light in the instrument cluster.

After an accident, the unit stores crash data and locks itself.

Why does the control unit 98820-5KX0A fail?

Stored crash data is the most common cause with the 98820-5KX0A, even if no airbag has deployed. Other causes are ageing electronic components, cold solder joints, moisture and corrosion, and voltage spikes.

A normal diagnostic tool cannot remove the crash data. It therefore remains in memory until the repair erases it.

• Ageing electronic components lose their function.
• Cold solder joints can lose contact.
• Moisture and corrosion attack connectors.
• Voltage spikes, for example from a weak battery or a jump start, put strain on the electronics.

How can you tell that the 98820-5KX0A is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently. A fault message also appears in the instrument cluster, the diagnostic tool cannot reach the control unit, and the fault memory cannot be cleared.

As long as these signs are present, airbags and seatbelt pretensioners may fail to deploy in an emergency.
