Airbag control unit with part number 98820 2X800

What does the airbag control unit 98820 2X800 do?

The airbag control unit 98820 2X800 controls the SRS restraint system for the Nissan. It evaluates the signals from the crash sensors, selects in an accident within split seconds the airbags and seatbelt pretensioners to trigger, and monitors the system continuously.

It indicates faults via the airbag warning light in the instrument cluster, so that you notice them immediately in everyday use.

After an accident it stores crash data and locks itself. Only the repair lifts this lock.

Why does the control unit 98820 2X800 fail?

Stored crash data is the most common cause, even if no airbag was triggered. A normal diagnostic tool cannot erase it. Aged components, moisture and voltage spikes also count among the possible causes.

Crash data remains in the memory even if the vehicle then continues to drive normally. Airbag24 removes it as part of the repair.

The other causes include the ageing of the electronics, cold solder joints on circuit boards, moisture and corrosion at plugs, and voltage spikes that occur, for example, when starting with a weak battery or with a jump start.

How can you tell that the 98820 2X800 is defective?

A defect shows first through the airbag warning light in the instrument cluster, through fault messages in the instrument cluster, or through a diagnostic tool with no connection to the control unit. A fault memory that cannot be cleared is also a sign.

• airbag warning light stays on continuously or comes on intermittently
• fault message in the instrument cluster
• diagnostic tool receives no connection to the control unit
• fault memory remains even after an attempt to clear it

If one of these signs is present, airbags and seatbelt pretensioners may possibly fail to trigger in an emergency.
