Airbag control unit with part number 98820-5CG0A

What does the airbag control unit 98820-5CG0A do?

The 98820-5CG0A is the central control unit of the restraint system (SRS) for Infiniti. It processes the signals from the crash sensors and decides in an accident, within milliseconds, on the triggering of airbags and seatbelt pretensioners.

The unit also monitors the entire system in the background and reports faults via the airbag warning light in the instrument cluster.

After an accident, it stores crash data and locks itself. The sensors supply data, but it is evaluated in this unit alone.

Why does the control unit 98820-5CG0A fail?

On the 98820-5CG0A, stored crash data from an earlier accident is the most common cause, even if no airbag was triggered. Other possible causes are aging electronics, cold solder joints, moisture and corrosion on plugs, and voltage spikes.

A normal diagnostic tool cannot remove crash data. Airbag24 erases it specifically during the repair.

Electronic components can age over time, and cold solder joints also lead to faults.

Voltage spikes, for example from a weak battery or from starting with external power, can stress the electronics.

How can you tell that the 98820-5CG0A is defective?

On the 98820-5CG0A, a defect shows through an airbag warning light in the instrument cluster that stays on permanently or intermittently. An error message in the instrument cluster, a missing connection of the diagnostic tool or a fault memory that cannot be cleared also indicate a problem.

In this case, airbags and seatbelt pretensioners may possibly not trigger in an emergency.

Such a display should be checked promptly.
