Airbag control unit with part number 95910-CL220

What does the airbag control unit 95910-CL220 do?

As the central control unit of the restraint system (SRS) for Hyundai, the airbag control unit 95910-CL220 processes the sensor values, evaluates accidents and controls the airbags and seatbelt pretensioners.

The decision on triggering is made within milliseconds. The electronics constantly monitor the wiring and components, and faults appear on the airbag warning light.

After an accident, the unit records crash data and then locks itself.

Why does the control unit 95910-CL220 fail?

The most common cause of the 95910-CL220 failing is crash data stored after an accident, even without a triggered airbag, which cannot be erased with a normal diagnostic tool. In general, aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes are also possible causes.

Crash data is an entry in the memory, not component damage. Airbag24 erases it during the repair, after the unit has been checked.

In addition, aged components, cold solder joints, and moisture and corrosion at contacts play a role. Voltage spikes, for example from a weak battery or jump-starting, put extra strain on the electronics.

How can you tell that the 95910-CL220 is defective?

A defect in the 95910-CL220 shows up through the airbag warning light, through error messages in the instrument cluster, through a missing connection to the diagnostic tool and through a fault memory that cannot be cleared. In that case, airbags and seatbelt pretensioners may possibly fail to deploy in a real emergency.

These signs at a glance:

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

As soon as one of these signs appears, a check is advisable.
