Airbag control unit with part number 98820-6HA0A

What does the airbag control unit 98820-6HA0A do?

The airbag control unit 98820-6HA0A manages the restraint system (SRS) in the Infiniti. It evaluates the signals from the crash sensors, decides in an accident on triggering airbags and seatbelt pretensioners, and checks the system continuously.

The unit stores faults it detects in the fault memory and displays them via the airbag warning light.

After an accident, it writes crash data and locks itself. Without a functioning control unit, the restraint system cannot perform its task.

Why does the control unit 98820-6HA0A fail?

The most common cause for the 98820-6HA0A is crash data stored after an accident, even if no airbag was triggered. Further causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

• outdated electronic components
• cold solder connections
• moisture and corrosion on the contacts
• voltage spikes, for example with a weak battery or jump leads

Crash data cannot be erased with a usual diagnostic tool. Airbag24 removes it during the repair.

Which of these causes applies in an individual case is only shown by reading out the fault memory.
