Airbag control unit with part number 98820-6JR1A

What does the airbag control unit 98820-6JR1A do?

The airbag control unit 98820-6JR1A coordinates the SRS in the vehicle of Infiniti. It processes the measured values from the crash sensors and decides in a collision within milliseconds which airbags and seatbelt pretensioners fire. Faults in the system are reported via the airbag warning light.

After an accident, the unit stores crash data and then remains locked. Only a repair lifts this lock.

The control unit runs throughout the entire journey and continuously checks its sensors for plausibility.

Why does the control unit 98820-6JR1A fail?

The most common cause is crash data stored after an accident, even if no airbag has opened. Other possible causes are ageing components, cold solder joints, moisture at plugs and voltage spikes.

Crash data cannot be removed with an ordinary diagnostic tool. Airbag24 deletes it as part of the repair.

Electronics age, and solder joints can go cold over time. Moisture and corrosion at plug connections can cause intermittent faults, as can voltage spikes, for example from a weak battery or when starting with an external power source.

How can you tell that the 98820-6JR1A is defective?

A defect shows up through the airbag warning light, which lights up permanently or intermittently, through a fault message in the instrument cluster, through a missing connection between the diagnostic tool and the control unit, and through a fault memory that cannot be cleared. Airbags and seatbelt pretensioners may then not trigger in an emergency.

The warning light in the instrument cluster is the most important hint your vehicle gives you.

• airbag warning light stays on permanently or comes on intermittently
• fault message in the instrument cluster
• diagnostic tool receives no connection to the control unit
• fault memory cannot be cleared

Have a lit warning light checked promptly.
