Airbag control unit with part number 98820-7FH0A

What does the airbag control unit 98820-7FH0A do?

The airbag control unit 98820-7FH0A manages the restraint system (SRS) of Nissan. It receives signals from the crash sensors, decides in an accident about airbags and seatbelt pretensioners, and monitors the system continuously. It shows you faults via the airbag warning light.

After an accident, the unit records crash data and locks itself. The data remains stored in the control unit.

Why does the control unit 98820-7FH0A fail?

Stored crash data is the most common cause, even when no airbag has deployed. A normal diagnostic tool cannot remove it. Other causes are ageing electronics, dry solder joints, moisture and corrosion, and voltage spikes.

An accident in which no airbag deploys still affects the control unit, and you cannot see that from outside.

The other causes in detail:

• ageing electronic components
• dry solder joints
• moisture and corrosion on plug connectors
• voltage spikes, for example from a weak battery or a jump start

How can you tell that the 98820-7FH0A is defective?

A defect shows up as the airbag warning light in the instrument cluster, which lights up permanently or intermittently. Added to this are a fault message in the instrument cluster, a diagnostic tool without connection, and a fault memory that cannot be cleared. In that case, airbags and seatbelt pretensioners may not deploy in an emergency.

The warning light is a signal from the system itself. Trust that it does not light up for no reason, and have the fault memory read out.

Delaying the read-out wastes valuable time in the search for the cause.
