Airbag control unit with part number 98820-EZ60A

What does the airbag control unit 98820-EZ60A do?

The airbag control unit 98820-EZ60A coordinates the SRS restraint system in Nissan. From the crash sensors it reads accident signals, decides within milliseconds on the triggering of airbags and seatbelt pretensioners, and checks the system for faults continuously.

The unit stores the faults it finds and shows them via the airbag warning light.

Crash data is stored in the control unit after an accident; after that it is locked.

Why does the control unit 98820-EZ60A fail?

The most common cause is stored crash data after an accident, even without a triggered airbag; a standard diagnostic tool cannot erase it. In addition, aged components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes are possible causes.

Crash data remains in the control unit until it is deliberately erased, and no common diagnostic tool can reach it.

Aged components and cold solder joints can cause faults that have nothing to do with an accident.

Moisture and corrosion at plug connectors are just as much a factor, as are voltage spikes, for example from a weak battery or a jump start.

How can you tell that the 98820-EZ60A is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and a fault message also appears. The diagnostic tool finds no connection to the control unit, and the fault memory cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

The airbag warning light in the instrument cluster is the sign you will see fastest. If it lights up permanently or only occasionally, the system has detected a fault.

If no connection to the diagnostic tool can be established or an entry remains in the fault memory, that is a further indication. Both are to be taken seriously, because the function may be impaired in an emergency.
