Airbag control unit with part number 98820-5R10A

What does the airbag control unit 98820-5R10A do?

The airbag control unit 98820-5R10A controls the SRS restraint system of Nissan. It checks the signals from the crash sensors and determines within milliseconds in a crash which airbags and seatbelt pretensioners fire. It also monitors all components of the system.

If it detects a fault, the airbag warning light comes on. After an impact it stores crash data and then remains locked.

Why does the control unit 98820-5R10A fail?

The most common cause is crash data stored in the control unit after an accident, even if no airbag has deployed; common diagnostic tools cannot remove it. In addition there are aged electronics, cold solder joints, moisture and corrosion on plugs, as well as voltage spikes.

The data remain in the memory, regardless of how the vehicle continues to run afterwards.

Other causes act gradually: ageing and moisture affect the electronics. Cold solder joints can lose contact, and voltage spikes, for example from a weak battery or jump-starting, strain the circuit.

How can you tell that the 98820-5R10A is defective?

The airbag warning light in the instrument cluster lights up or flashes, an error message appears, the diagnostic tool does not find the control unit, or the fault memory cannot be cleared. Airbags and seatbelt pretensioners may then fail to deploy in an emergency.

The warning light is the clearest indication the vehicle gives. Have the system checked promptly so that the fault can be identified.
