Airbag control unit with part number 98820-1EB1A

What does the airbag control unit 98820-1EB1A do?

The airbag control unit 98820-1EB1A forms the central control unit of the restraint system (SRS) for Nissan. It evaluates the signals from the crash sensors, determines within milliseconds in the event of an accident which airbags and seatbelt pretensioners are triggered, and monitors the system continuously. It indicates any faults that occur via the airbag warning light.

The crash sensors deliver their readings to the control unit, which evaluates them continuously.

After an accident the unit stores crash data and locks itself. In normal operation it goes unnoticed, because it works in the background, and that is exactly why the warning light is the direct indication the vehicle gives.

Why does the control unit 98820-1EB1A fail?

The most common cause with the 98820-1EB1A is crash data stored after an accident, even if no airbag has deployed. In addition, electronic components age, solder joints can be cold, moisture and corrosion attack plug connections, and voltage spikes occur, for example with a weak battery or a jump start.

Crash data cannot be erased with a normal diagnostic tool. Airbag24 erases it during the repair.

The remaining causes develop over a longer period, for example when connections become damp or components age. They therefore do not necessarily occur suddenly.

How can you tell that the 98820-1EB1A is defective?

A defect shows itself through the airbag warning light in the instrument cluster, which lights up permanently or intermittently. Fault messages in the instrument cluster, a diagnostic tool without a connection to the control unit, and a fault memory that cannot be cleared also indicate a fault in the 98820-1EB1A.

As long as the fault persists, airbags and seatbelt pretensioners may not be able to trigger in an emergency.

A lit warning light is therefore a finding that you should have checked promptly.
