Airbag control unit with part number 98820-5KA1E

What does the airbag control unit 98820-5KA1E do?

The airbag control unit 98820-5KA1E is the central control unit of the restraint system (SRS) of Nissan. It evaluates crash sensors and, in an accident, determines within milliseconds which airbags and seatbelt pretensioners are triggered.

During operation it continuously checks whether the system is working and reports faults to the airbag warning light. After an accident it stores crash data and locks itself.

Why does the control unit 98820-5KA1E fail?

Stored crash data from an accident is the most common cause, even if no airbag has deployed. A normal diagnostic tool cannot erase this data. Aged components, cold solder joints, moisture or corrosion at plugs, and voltage spikes are also possible.

Voltage spikes arise, for example, from a weak battery or when a jump start is connected. Only the fault memory readout reveals which cause is actually present.

How can you tell that the 98820-5KA1E is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently. A fault message may also appear; in an emergency, airbags and seatbelt pretensioners may then not deploy.

A diagnostic tool that cannot establish a connection to the control unit, or a fault memory that cannot be cleared, also points to a problem. In that case, have the system checked.
