Airbag control unit with part number 98820-1ME0A

What does the airbag control unit 98820-1ME0A do?

The airbag control unit 98820-1ME0A is the control unit of the restraint system (SRS) for Infiniti. It processes the signals from the crash sensors, selects in a crash the airbags and seatbelt pretensioners that are to trigger, and monitors the system continuously.

It displays faults via the airbag warning light. After an accident it stores crash data and locks itself.

The control unit is therefore the switching point on which the entire restraint system relies.

Why does the control unit 98820-1ME0A fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed; with a normal diagnostic tool it cannot be erased. Further causes are:

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

The unit creates crash data as soon as the sensors identify an impact as relevant. That such data exists does not mean that an airbag has deployed.

Airbag24 takes care of the erasure as part of the repair, because it is not possible with a normal diagnostic tool.

How can you tell that the 98820-1ME0A is defective?

The airbag warning light lights up permanently or intermittently, an error message appears in the instrument cluster, or the diagnostic tool receives no connection to the control unit. A fault memory that cannot be cleared also belongs to this. In that case airbags and seatbelt pretensioners may not trigger in an emergency.

The airbag warning light in the instrument cluster indicates the fault as soon as the control unit has detected it. Whether it lights up permanently or only intermittently is not decisive for the check.

In addition there are error messages in the instrument cluster, as well as problems connecting to the diagnostic tool. A fault memory that remains despite an attempt to clear it is a further indication.

Please have the finding checked promptly, because airbags and seatbelt pretensioners may not trigger in an emergency.

Which vehicles is the 98820-1ME0A fitted in?

The control unit 98820-1ME0A is fitted in these vehicles: Infiniti M37 Y51 (2010-2013). You determine whether your car is included by make and model.

• Infiniti M37 Y51 (2010-2013)

Compare the part number on the label of the removed unit with this page. That only ensures that it is the right unit. Beforehand, have the fault memory read out, because only this 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 98820-1MA1C.
