Airbag control unit with part number 98820-6JR3A

What does the airbag control unit 98820-6JR3A do?

The airbag control unit 98820-6JR3A is the central control unit of the SRS for Infiniti. It processes the crash sensor data and, in the event of an impact, decides within milliseconds whether the airbags and seatbelt pretensioners are triggered.

It monitors the entire system continuously and indicates detected faults via the airbag warning light.

After an accident, it stores crash data and locks itself.

Why does the control unit 98820-6JR3A fail?

The most common cause with the 98820-6JR3A is stored crash data after an accident, even if no airbag has triggered. Other causes are ageing components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

An ordinary diagnostic tool cannot clear this data; the erasure takes place at Airbag24 as part of the repair.

The remaining causes concern the electronics and the power supply. Ageing components and cold solder joints lead to unreliable contacts, moisture and corrosion attack the plug connections, and voltage spikes occur, for example, with a weak battery or jump-starting.

How can you tell that the 98820-6JR3A is defective?

A fault in the 98820-6JR3A shows up through the airbag warning light, error messages in the instrument cluster, a missing connection to the diagnostic tool, or a fault memory that cannot be cleared.

The airbag warning light in the instrument cluster reliably indicates the fault. It lights up permanently or intermittently, and an accompanying error message may appear as well.

If the diagnostic tool remains without connection or the fault memory cannot be emptied, this is a further sign. Airbags and seatbelt pretensioners may then possibly not trigger in an emergency.

How does the repair of the 98820-6JR3A work?

First have the fault memory read out and enclose the log. Then disconnect the battery and only then remove the 98820-6JR3A. Create the repair order online, then pack the unit well for dispatch. Processing at Airbag24 normally takes 3–4 working days.

Airbag24 examines the unit on the test bench, replaces defective components, erases the crash data and carries out a function test. Only then does your own unit come back to you.

The 3–4 working days apply exclusively to testing, repairing and checking at Airbag24; your steps and the dispatch are to be considered separately.

Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
