Airbag control unit with part number 98820-5HR0A

What does the airbag control unit 98820-5HR0A do?

The airbag control unit 98820-5HR0A is the central control unit of the restraint system for Nissan. It evaluates the signals from the crash sensors, decides in the event of an accident within milliseconds on the triggering of airbags and seatbelt pretensioners, and monitors the system permanently during operation. After an accident it stores crash data and locks itself.

While driving, the unit continuously checks the components of the restraint system. If it detects a fault, it creates an entry in the fault memory and shows the fault via the airbag warning light in the instrument cluster.

The crash data record how an accident proceeded and remain stored in the control unit.

Why does the control unit 98820-5HR0A fail?

The most common cause is crash data stored after an accident, which cannot be erased with a normal diagnostic tool. Further causes are aged electronic components, cold solder joints, moisture and corrosion on plug connections, as well as voltage spikes, for example from a weak battery or jump-starting.

Crash data is present even if no airbag has triggered, because the control unit registered the event. A normal diagnostic tool cannot reach these entries, which is why the fault remains after the accident.

The other causes can arise from ageing and environmental influences. Cold solder joints and corrosion on plug connections lead to contact problems, and voltage spikes can stress the electronics.

How can you tell that the 98820-5HR0A is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and a fault message appears in the instrument cluster. The diagnostic tool cannot find the control unit, and a fault memory cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

• The airbag warning light in the instrument cluster lights up permanently or intermittently
• A fault message appears in the instrument cluster
• The diagnostic tool has no connection to the control unit
• The fault memory cannot be cleared

The warning light gives the clearest indication that the system has detected a fault. You should take it seriously and have the vehicle checked promptly.

Even if the warning light comes on only intermittently, it is a sign of a detected fault.
