Airbag control unit with part number 95910-CW300

What does the airbag control unit 95910-CW300 do?

The airbag control unit 95910-CW300 coordinates the restraint system (SRS) of Hyundai. From the signals of the crash sensors, it calculates in a fraction of a second during an accident which airbags and seatbelt pretensioners are triggered.

During operation it monitors the entire system. It records any faults it detects in the fault memory and shows them via the airbag warning light in the instrument cluster.

After an accident the unit stores crash data and locks itself. A failure of the control unit therefore affects the entire protection of the occupants.

Why does the control unit 95910-CW300 fail?

For 95910-CW300, the most common cause after an accident is stored crash data, even when no airbag has deployed. Other causes are ageing electronics, cold solder joints, moisture and corrosion at plugs, and voltage spikes.

Crash data stays in memory, even when nothing has been triggered at the airbags. A normal diagnostic tool cannot erase it. Airbag24 removes it during the repair.

Ageing electronic components and cold solder joints also lead to faults. Moisture and corrosion at plug connections are a further source.

Voltage spikes, for example from a weak battery or when jump-starting, put additional strain on the electronics.

How can you tell that the 95910-CW300 is defective?

A defect in the 95910-CW300 shows up through a lit airbag warning light, a fault message in the instrument cluster, a missing connection to the diagnostic tool and a fault memory that cannot be cleared.

• The airbag warning light in the instrument cluster lights up permanently or intermittently
• Fault message in the instrument cluster
• The diagnostic tool gets no connection to the control unit
• The fault memory cannot be cleared

With these signs, airbags and seatbelt pretensioners may not deploy in an emergency. A prompt check is therefore advisable.
