Airbag control unit with part number 98820-1EA0A

What does the airbag control unit 98820-1EA0A do?

The 98820-1EA0A is the SRS control unit of Nissan, the central control of the restraint system. It evaluates the crash sensors and decides in an accident which airbags and seatbelt pretensioners are triggered.

The unit checks the system continuously and reports faults via the airbag warning light in the instrument cluster. The triggering takes place within milliseconds.

After an accident it stores crash data and locks itself. The lock is lifted only by the repair.

Why does the control unit 98820-1EA0A fail?

The most common cause for the 98820-1EA0A is crash data stored after an accident, even if no airbag has been triggered. Other causes are ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Crash data cannot be cleared with a normal diagnostic tool. Airbag24 clears it during the repair.

Ageing electronic components and cold solder joints can cause a failure on their own. Moisture and corrosion at plug connections disrupt the contact, and voltage spikes, for example from a weak battery or a jump start, stress the electronics.

How can you tell that the 98820-1EA0A is defective?

A defect on the 98820-1EA0A shows up as the airbag warning light in the instrument cluster, which lights up permanently or intermittently. In addition there is a fault message, the diagnostic tool has no connection, and the fault memory cannot be cleared.

Typical signs at a glance:

• Airbag warning light on permanently or intermittently
• Fault message in the instrument cluster
• No connection between the diagnostic tool and the control unit
• Fault memory cannot be cleared

If one of these findings is present, airbags and seatbelt pretensioners may possibly not deploy in an emergency. The finding is therefore to be taken seriously.
