Airbag control unit with part number 98820-5CK0A

What does the airbag control unit 98820-5CK0A do?

The control unit 98820-5CK0A controls the restraint system of Infiniti as the SRS control unit. It evaluates the signals of the crash sensors and decides in a collision, within milliseconds, which airbags and seatbelt pretensioners are triggered.

Between accidents the unit monitors the entire system continuously. If it finds a fault, it reports it via the airbag warning light, which is visible in the instrument cluster.

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

Why does the control unit 98820-5CK0A fail?

The most common cause for the 98820-5CK0A is crash data stored after an accident, even if no airbag has deployed. A normal diagnostic tool does not delete it. Other causes include aged components, cold solder joints, moisture and corrosion, and voltage spikes.

Crash data is stored in the unit, and removing it is part of the repair. The further causes at a glance:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or jump-starting

Which of these applies is revealed only by the read-out fault memory.

How can you tell that the 98820-5CK0A is defective?

A defect on the 98820-5CK0A shows itself through an airbag warning light that is on constantly or intermittently, and through fault messages in the instrument cluster. In addition, the diagnostic tool gets no connection to the control unit, and the fault memory cannot be cleared. Then airbags and seatbelt pretensioners may possibly fail to deploy in an emergency.

In detail, the following signs occur:

• airbag warning light is on constantly or intermittently
• fault message in the instrument cluster
• no connection between diagnostic tool and control unit
• fault memory cannot be cleared

The warning light makes the state of the system visible. Have a fault cleared promptly, even if the vehicle runs normally in everyday use.
