Airbag control unit with part number 98820-JY30A

What does the airbag control unit 98820-JY30A do?

The airbag control unit 98820-JY30A is the control centre of the restraint system in Renault vehicles. It evaluates the signals from the crash sensors, decides within a very short time in an accident about airbags and seatbelt pretensioners, and monitors the entire system.

If it detects a fault, the airbag warning light in the instrument cluster lights up. After an accident it stores crash data and then locks itself.

Monitoring runs in the background.

Why does the control unit 98820-JY30A fail?

In the 98820-JY30A, crash data stored in memory from an accident is the most common cause, even without a triggered airbag. A normal diagnostic tool cannot remove it. In addition there are aged electronics, cold solder joints, corrosion at plug connections and voltage spikes.

Airbag24 removes the crash data as part of the repair. You do not have to remove the data yourself.

Aged electronics eventually develop intermittent contacts. Cold solder joints, moisture and rust on the connectors also belong to the causes, and a weak battery or a jump-start can cause voltage spikes as well.

How can you tell that the 98820-JY30A is defective?

On the 98820-JY30A, the airbag warning light in the instrument cluster stays on permanently or intermittently. In addition an error message appears in the instrument cluster, the diagnostic tool does not find the control unit, and a fault memory cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may not trigger. A lit warning light is therefore a reason to act promptly.

A plug or a cable can also cause these signs. Only the read-out of the fault memory gives clarity here.

You compare the part number with this page on the label of the removed unit; this only confirms that the unit fits. Have the fault memory read out beforehand, because only the log shows whether the control unit or a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 8200963406, 985106952R, 98820JY00A, 98820JY10A.

How does the repair of the 98820-JY30A work?

For the 98820-JY30A, first have the fault memory read out and enclose the log. Then disconnect the battery and only then remove the control unit. Afterwards create a repair order online and send in the unit well packed. Airbag24 checks it, replaces defective components, erases the crash data and carries out a function test.

The sequence is safety-relevant, so keep to it exactly.

Airbag24 needs 3–4 working days for inspection, repair and testing. After that your own unit goes back to you. 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.

How does the control unit 98820-JY30A get to Airbag24?

You send the control unit 98820-JY30A to Airbag24 as a parcel, or alternatively a UPS collection is booked for an extra charge. After the repair, Airbag24 returns it to you by UPS.

The printed repair order belongs in the parcel, and the control unit should be packed shock-proof.
