Airbag control unit with part number 98820-9PE0A

What does the airbag control unit 98820-9PE0A do?

The airbag control unit 98820-9PE0A coordinates the restraint system (SRS) in Nissan. It evaluates signals recorded during an impact, decides within milliseconds on airbags and seatbelt pretensioners, and continuously monitors the condition of the system.

Detected faults are shown via the airbag warning light in the instrument cluster, and the fault memory records them.

If an accident happens, crash data is stored and the unit locks itself.

Why does the control unit 98820-9PE0A fail?

Stored crash data from an earlier accident is the most common cause on the 98820-9PE0A, even if no airbag was deployed. A standard diagnostic tool cannot erase it. Aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes are also possible causes.

The unit also records crash data when no airbag deploys.

Old electronics and cold solder joints cause faults that only show up intermittently.

Moisture and corrosion at plug connections impair the contact, and voltage spikes from the vehicle electrical system, for example with a weak battery or jump-starting, put additional strain on the unit.

How can you tell that the 98820-9PE0A is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently on the 98820-9PE0A. An error message in the instrument cluster, a diagnostic tool without a connection and a fault memory that cannot be cleared come on top. In that case airbags and seatbelt pretensioners may not deploy in an emergency.

The light is the direct sign that the system has detected a fault.

An error message also calls for a prompt check, so that the cause is identified.

Which vehicles is the 98820-9PE0A fitted in?

This selection of vehicles is known to us for this part number:

• Nissan Pathfinder R52 Facelift (2016-2021)
• Nissan Pathfinder R52 (2013-2016)

First compare the part number on the label of the removed unit with this page; that only confirms that it is the right unit. Have the fault memory read out before removal, because only the result shows whether the control unit is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 285013305, 98820-9PC5A, 98820-9WD1A.

How does the repair of the 98820-9PE0A work?

For the 98820-9PE0A, the sequence is as follows: read out the fault memory and enclose the log, then disconnect the battery and only then remove the control unit. Next, create a repair order online and send in the well-packed unit; processing at Airbag24 usually takes 3–4 working days.

At Airbag24 the unit is checked on the test bench, defective components are repaired, the crash data is erased and a function test is run. You then get your own unit back.

The 3–4 working days only concern the work at Airbag24. 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 98820-9PE0A get to Airbag24?

You send the 98820-9PE0A control unit as a parcel or book a UPS collection for an extra charge. After the repair, Airbag24 sends your own unit back by UPS.

Put the printed repair order into the parcel; for the unit, choose shock-resistant packaging.
