Airbag control unit with part number 95910-2E300

What does the airbag control unit 95910-2E300 do?

The airbag control unit 95910-2E300 is the central control unit of the restraint system (SRS) in Hyundai vehicles. It evaluates the signals from the crash sensors and decides which airbags and seatbelt pretensioners are triggered in an accident.

The evaluation takes place in milliseconds. At the same time, the control unit monitors the entire system and shows faults via the airbag warning light.

After an accident it stores crash data and locks itself.

Why does the control unit 95910-2E300 fail?

Stored crash data is the most common cause when the control unit 95910-2E300 fails, even if no airbag has deployed. A normal diagnostic tool cannot erase it. Aged components, cold solder joints, moisture and corrosion, and voltage spikes also play a role.

This data remains in the unit even if nothing noticeable is found on the vehicle apart from the accident. At Airbag24 it is erased during the repair.

Other causes lie more in the electronics and the connections. Moisture and corrosion attack plug connectors, and voltage spikes arise, for example, from a weak battery or when starting with jump leads.

How can you tell that the 95910-2E300 is defective?

A defect on the 95910-2E300 shows up mainly through the airbag warning light in the instrument cluster. It lights up permanently or intermittently, and further signs may be added:

These signs indicate a fault in the control unit or in its connection.

• Fault message in the instrument cluster
• The diagnostic tool receives no connection to the control unit
• The fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may then not deploy.
