Airbag control unit with part number 98820-6HR0A

What does the airbag control unit 98820-6HR0A do?

The airbag control unit 98820-6HR0A controls the restraint system (SRS) for Nissan. It evaluates the signals from the crash sensors, decides in a crash within milliseconds on the triggering of airbags and seatbelt pretensioners, and monitors the system continuously.

If it detects a fault, it indicates this via the airbag warning light in the instrument cluster. The evaluation runs in the background throughout the entire journey.

After an accident the control unit stores crash data and locks itself.

Why does the control unit 98820-6HR0A fail?

On the 98820-6HR0A, stored crash data after an accident is the most common cause, even if no airbag has triggered. Other causes in brief:

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

Crash data cannot be erased with a normal diagnostic tool. The fault therefore remains in the memory until the unit has been examined.

The remaining causes concern the electronics themselves. Components age, solder joints can go cold, and moisture or corrosion at connectors disturb the signal transmission.

How can you tell that the 98820-6HR0A is defective?

A defect on the 98820-6HR0A shows itself in the airbag warning light in the instrument cluster, which lights up permanently or intermittently. In addition there is a fault message in the instrument cluster, no connection from the diagnostic tool to the control unit, or a fault memory that cannot be cleared.

• Warning light permanently or intermittently on
• Fault message in the instrument cluster
• Diagnostic tool has no connection to the control unit
• Fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may possibly not trigger with such a defect. Please have the fault checked promptly.
