Airbag control unit with part number 98820 5X10A

What does the airbag control unit 98820 5X10A do?

The 98820 5X10A is the airbag control unit for the restraint system (SRS) of Nissan. It receives the signals from the crash sensors, selects the airbags and seatbelt pretensioners to trigger in a collision within milliseconds, and monitors the system permanently. If it detects a fault, it reports it via the airbag warning light.

After an accident it stores crash data and locks itself.

The sensor evaluation runs without interruption, so that the decision does not lose time in an emergency.

Why does the control unit 98820 5X10A fail?

The most common cause is a memory entry from an accident: crash data remains stored, even if no airbag has deployed. Further causes in brief:

• Aged electronic components
• Cold solder joints
• Moisture and corrosion on plug connections
• Voltage spikes, for example from a weak battery or a jump start

A normal diagnostic tool cannot access the crash data.

Which of these points applies in the individual case is determined only by fault finding.

How can you tell that the 98820 5X10A is defective?

A defect first shows up as the airbag warning light in the instrument cluster, or as an error message there. If no connection can be made to the diagnostic tool, or the fault memory cannot be cleared, that is a further finding. In an emergency, airbags and seatbelt pretensioners could possibly fail to trigger as a result.

The warning light shows when the system itself has detected a deviation. It is therefore a direct indication, not a chance finding.

Even a finding that does not occur constantly deserves a check, because faults can recur in operation.
