Airbag control unit with part number 98820-5RM0C

What does the airbag control unit 98820-5RM0C do?

The airbag control unit 98820-5RM0C manages the airbags and seatbelt pretensioners in the restraint system (SRS) of Nissan. In a crash, it uses the crash sensors to determine which restraint devices must be triggered, and it checks the system while the vehicle is in operation. Faults are shown by the airbag warning light, which you can see in the instrument cluster.

Triggering takes place within milliseconds, which is why the electronics work without delay.

After an accident, the unit stores crash data and locks itself.

Why does the control unit 98820-5RM0C fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered; a normal diagnostic tool cannot erase it. Other possible causes are ageing electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes.

Moisture and corrosion mainly affect the plug connections. Cold solder joints and ageing components are hard to spot from the outside.

Voltage spikes also belong here, for example when the battery is weak or when a jump start is given.

How can you tell that the 98820-5RM0C is defective?

The clearest sign is an airbag warning light in the instrument cluster that stays on permanently or comes on intermittently. Other signs include fault messages in the instrument cluster, no connection to the diagnostic tool and a fault memory that cannot be cleared.

The signs at a glance:

• Airbag warning light on permanently or intermittently
• Fault message in the instrument cluster
• Diagnostic tool receives no connection to the control unit
• Fault memory cannot be cleared

While such a fault exists, airbags and seatbelt pretensioners may not trigger in an emergency. If you see any of these signs, have the system checked quickly.
