Airbag control unit with part number 98820-5XH0A

What does the airbag control unit 98820-5XH0A do?

The airbag control unit 98820-5XH0A is the central control unit of the SRS restraint system of Nissan. It evaluates the crash sensors, decides within milliseconds on the triggering of airbags and seatbelt pretensioners, and monitors all components continuously.

To do this, it continuously assesses the sensor measured values. In the event of an impact it compares them with the requirements for triggering. At the same time it checks the connections and components and stores detected faults in the fault memory.

After an accident, the control unit stores crash data and locks itself afterwards. The lock is only lifted by the repair.

Why does the control unit 98820-5XH0A fail?

The most common cause of the 98820-5XH0A is crash data stored after an accident, even without a triggered airbag. In addition there are ageing electronic components, cold solder joints, moisture and corrosion on plug connectors, and voltage spikes.

Crash data cannot be deleted with a normal diagnostic tool. Airbag24 deletes it during the repair, which is why this step is not skipped.

The other causes lie in the electronics and their surroundings. Electronics age, solder joints can become cold, and moisture attacks plug connections. Voltage spikes, for example from a weak battery or a jump start, also stress the unit.

How can you tell that the 98820-5XH0A is defective?

The airbag warning light in the instrument cluster stays on constantly or intermittently, and an error message appears in the instrument cluster. The diagnostic tool cannot establish a connection to the 98820-5XH0A, and the fault memory cannot be cleared.

As long as this finding exists, airbags and seatbelt pretensioners may not deploy in an emergency.

The light is therefore a serious signal and not a minor matter.
