Airbag control unit with part number 98820-5CE0A

What does the airbag control unit 98820-5CE0A do?

The airbag control unit 98820-5CE0A performs control of the restraint system (SRS) for Infiniti. It processes the signals from the crash sensors, decides in an emergency within milliseconds on airbags and seatbelt pretensioners, and keeps the system under observation. It indicates faults via the airbag warning light.

Observation takes place without interruption as soon as the control unit is in operation. As a result, a fault is quickly noticed before it spreads.

After an accident it creates crash data and locks itself afterwards. You must keep this fact in mind during any further examination.

Why does the control unit 98820-5CE0A fail?

Crash data from an accident is the most common cause, even without a triggered airbag. Deleting it is not possible with an ordinary diagnostic tool. In addition, aged components, cold solder joints, wetness at plug connections and voltage spikes can favour the failure.

Since the crash data is stored in the control unit itself, such a fault remains even when cables and plugs are in perfect condition.

Ageing and cold solder joints act rather gradually, whereas voltage spikes, for example from a weak battery or a jump start, occur suddenly. Both belong to the general list of possible triggers.

How can you tell that the 98820-5CE0A is defective?

On the unit itself a defect can show through the instrument cluster. There the airbag warning light lights up permanently or intermittently, and a fault message is displayed. If the diagnostic tool does not connect to the control unit, or the fault memory remains, that is a clear sign.

In everyday use such a thing is easy to notice, but can be overlooked. A check is therefore recommended as soon as one of these signs occurs.

In an emergency, airbags and seatbelt pretensioners may fail to trigger.
