Airbag control unit with part number 98820-6JR0A

What does the airbag control unit 98820-6JR0A do?

The airbag control unit 98820-6JR0A is the central control unit of the restraint system (SRS) for Infiniti. It evaluates the crash sensors and decides in an accident, within milliseconds, which airbags and seatbelt pretensioners are triggered.

The unit monitors the system continuously. It shows faults via the airbag warning light in the instrument cluster.

After an accident it stores crash data and locks itself. Only the repair lifts the lock.

Why does the control unit 98820-6JR0A fail?

The most common cause is crash data stored after an accident, even if no airbag has fired; a normal diagnostic tool cannot remove it. Other causes are aged electronic components, cold solder joints, moisture and corrosion on plug connectors, and voltage spikes.

Stored crash data is the trace of an accident in the control unit. Airbag24 erases it during the repair.

Aged electronic components and cold solder joints lead to malfunctions over time. Moisture and corrosion on the plug connectors impair signal transmission.

Voltage spikes, for example from a weak battery or a jump start, can also stress the electronics.

How can you tell that the 98820-6JR0A is defective?

A defect in the control unit 98820-6JR0A shows itself through the airbag warning light, which lights up constantly or intermittently, through fault messages in the instrument cluster, through no connection to the diagnostic tool, or through a fault memory that cannot be cleared.

The warning light is the clearest sign. It signals that the restraint system has detected a fault.

In this case airbags and seatbelt pretensioners may not deploy in an emergency. Arrange an inspection promptly.
