Airbag control unit with part number 98820-6RY0B

What does the airbag control unit 98820-6RY0B do?

The airbag control unit 98820-6RY0B controls the restraint system (SRS) of Nissan. It evaluates the signals from the crash sensors and decides in an accident which airbags and seatbelt pretensioners are triggered.

During operation, it monitors the system continuously. If it detects a fault, it reports it via the airbag warning light in the instrument cluster.

After an accident, the unit stores crash data and locks itself. Only the repair lifts this lock.

Why does the control unit 98820-6RY0B fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. Other triggers are aged components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes. Crash data cannot be removed with a normal diagnostic tool; Airbag24 removes it during the repair.

Crash data arises even when no airbag has deployed. It stays stored in the unit until Airbag24 removes it, so an attempt to erase it with the diagnostic tool does not help.

The other causes act more gradually: electronic components age, solder joints can go cold, and moisture attacks the contacts. Voltage spikes, for example with a weak battery or a jump start, can also cause damage.

Which of these applies to your unit is shown only by reading out the fault memory and by the check on the test bench.

How can you tell that the 98820-6RY0B is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently. In addition, there is a fault message in the instrument cluster, a missing connection from the diagnostic tool to the control unit, and a fault memory that cannot be cleared.

If these signs appear, the airbags and seatbelt pretensioners may not deploy in an emergency. Such a finding calls for a prompt check.

The signs at a glance:

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