Airbag control unit with part number 98820 9H606

What does the airbag control unit 98820 9H606 do?

The airbag control unit 98820 9H606 is the control unit of the restraint system (SRS) in Nissan. It evaluates the signals from the crash sensors and decides in an accident which airbags and seatbelt pretensioners are triggered.

It monitors the system without interruption. If it detects a fault, it shows this via the airbag warning light.

After an accident, it stores crash data and locks itself.

Why does the control unit 98820 9H606 fail?

The most common cause is crash data from an accident that remains stored in the unit, even without a triggered airbag. Aged electronics, dry solder joints, moisture at plug connections and voltage spikes are also possible causes.

Crash data cannot be erased with a normal diagnostic tool; Airbag24 erases it during the repair.

Further possible causes:

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

How can you tell that the 98820 9H606 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently as soon as the 98820 9H606 has a defect. A fault message in the instrument cluster, a missing contact with the diagnostic tool or a fault memory that cannot be cleared support the suspicion.

In that case, airbags and seatbelt pretensioners may not trigger in an emergency. Do not ignore the warning light; have it checked promptly instead.
