Airbag control unit with part number 98820-6TL0B

What does the airbag control unit 98820-6TL0B do?

The 98820-6TL0B processes the signals of the crash sensors in the restraint system (SRS) of Nissan. In a crash, it decides which airbags and seatbelt pretensioners are triggered. It indicates faults via the airbag warning light in the instrument cluster.

Monitoring runs continuously, so that the system is ready in an emergency.

After a crash, the control unit records crash data and locks itself. The lock is lifted only by the repair.

Why does the control unit 98820-6TL0B fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. A normal diagnostic tool cannot erase it. Other causes are also possible: aged components, cold solder joints, moisture and corrosion on plugs, and voltage spikes.

Crash data cannot be seen from outside and remains stored in the unit.

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

The list gives general causes that may come into question in the event of a failure.

How can you tell that the 98820-6TL0B is defective?

A defect shows itself when the airbag warning light is on permanently or intermittently, or when a fault message appears in the instrument cluster. The diagnostic tool then receives no connection to the control unit, or the fault memory cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

Typical signs include:

• airbag warning light on permanently or intermittently
• fault message in the instrument cluster
• no connection between the diagnostic tool and the control unit
• fault memory cannot be cleared

A single one of these signs is enough to justify checking the system.
