Airbag control unit with part number 98820-1EE0A

What does the airbag control unit 98820-1EE0A do?

The 98820-1EE0A is the central control unit for the restraint system (SRS) of Nissan. It evaluates the signals from the impact sensors, selects the airbags and seatbelt pretensioners to be triggered within milliseconds in an accident, and monitors the entire system.

If it detects a fault, this is displayed via the airbag warning light. After an accident it stores crash data and locks itself.

The system consists of several components that only work together. The control unit is the point where the messages converge.

Why does the control unit 98820-1EE0A fail?

With the 98820-1EE0A, the most common cause is crash data stored after an accident, even without a triggered airbag. A normal diagnostic tool cannot erase this crash data.

Aged components in the control unit, cold solder joints and moisture at plug connections are further possible causes.

Voltage peaks can also stress the electronics, for example with a weak battery or a jump start. Which cause applies is shown by reading the fault memory.

How can you tell that the 98820-1EE0A is defective?

You can recognise a defect in the 98820-1EE0A by the airbag warning light, which lights up permanently or intermittently, or by a fault message on the instrument cluster. In addition, the fault memory cannot be cleared and the diagnostic tool finds no connection to the control unit. In that case, the airbags and seatbelt pretensioners may not trigger in an emergency.

Please have a permanently lit warning light checked promptly.

Comparing the part number on the label of the removed unit with this page ensures that it is the right unit. However, this says nothing about the cause. Therefore, have the fault memory read before removal, because only the result shows whether the control unit is defective or whether a plug or cable is the cause.
