Airbag control unit with part number 98820-ZX10A

What does the airbag control unit 98820-ZX10A do?

The airbag control unit 98820-ZX10A is the central control unit of the restraint system (SRS) for Nissan. It processes the signals from the crash sensors, decides within milliseconds in a crash whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously. It shows faults via the airbag warning light.

The ongoing monitoring covers sensors, wiring and output stages. It runs in the background, so you do not have to operate anything.

After an accident, the unit stores crash data and locks itself. Only the repair lifts this lock.

Why does the control unit 98820-ZX10A fail?

The most common cause with the 98820-ZX10A is crash data stored after an accident, even when no airbag was triggered. Other causes are aged electronics, cold solder joints, moisture and corrosion, and voltage spikes.

A normal diagnostic tool cannot remove this data. That is why the fault persists despite repair attempts on the wiring harness, until the data is erased at Airbag24.

Aged electronics and cold solder joints impair the function gradually. Moisture and corrosion at plug connections lead to contact problems. Voltage spikes, for example from a weak battery or a jump start, put additional strain on the electronics.

How can you tell that the 98820-ZX10A is defective?

A defect on the 98820-ZX10A shows up as the airbag warning light in the instrument cluster, which lights up permanently or intermittently. Added to this, there may be a fault message in the instrument cluster and a diagnostic tool that cannot connect to the control unit.
