Airbag control unit with part number 98820-9DM0A

What does the airbag control unit 98820-9DM0A do?

The airbag control unit 98820-9DM0A controls the restraint system (SRS) at Nissan. It evaluates the signals of the crash sensors, decides in an accident within milliseconds whether airbags and seatbelt pretensioners are triggered, and then locks itself. After an accident it stores crash data.

Monitoring runs continuously. The unit indicates faults via the airbag warning light in the instrument cluster.

Why does the control unit 98820-9DM0A fail?

The most common cause is an entry of crash data stored after an accident, even if no airbag was triggered. Aging electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes are further possible causes.

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

The other causes come from age, moisture and electrical voltage spikes, for example from a weak battery or a jump start.

How can you tell that the 98820-9DM0A is defective?

A defect in the 98820-9DM0A is indicated by the airbag warning light, which stays on permanently or intermittently. In addition, an error message appears in the instrument cluster, the diagnostic tool gets no connection, and the fault memory cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may not trigger in a disturbed system. Have the display checked rather than ignoring it.
