Airbag control unit with part number 98820-5R80A

What does the airbag control unit 98820-5R80A do?

The airbag control unit 98820-5R80A is the central control unit of the restraint system (SRS) in Nissan. It evaluates the signals from the crash sensors and decides in an accident within milliseconds which airbags and seatbelt pretensioners are triggered.

In addition, it monitors the entire system permanently. If it detects a fault, it reports it 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 98820-5R80A fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered. A normal diagnostic tool cannot delete it. Other causes include ageing components, cold solder joints, moisture and corrosion, and voltage spikes.

As long as the crash data remains in the memory, the fault persists. The further causes in detail are:

• ageing electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example with a weak battery or jump start

How can you tell that the 98820-5R80A is defective?

A defect shows up as the airbag warning light in the instrument cluster, which stays on permanently or intermittently, and as a fault message in the instrument cluster. In addition, the diagnostic tool finds no connection to the control unit, and the fault memory cannot be cleared.

Typical signs at a glance:

• Airbag warning light stays on permanently or intermittently
• Fault message in the instrument cluster
• No connection between diagnostic tool and control unit
• Fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may then fail to deploy. Have the vehicle checked promptly.
