Airbag control unit with part number 86250-38080

What does the airbag control unit 86250-38080 do?

For SsangYong, the airbag control unit 86250-38080 controls the restraint system (SRS). It reads the crash sensors, determines in an accident which airbags and seatbelt pretensioners are triggered, and checks the system continuously. After an accident it stores crash data and locks itself.

In the vehicle, the unit works unobtrusively in the background. If it finds a fault, the airbag warning light comes on and the fault is stored in the fault memory.

All protection provided by airbags and seatbelt pretensioners depends on this control unit working correctly.

Why does the control unit 86250-38080 fail?

The most common cause on the 86250-38080 is crash data stored after an accident, even if no airbag has deployed, and a normal diagnostic tool cannot erase it. Other causes are aged electronic components, cold solder joints, moisture on plug connections and voltage spikes.

Airbag24 erases crash data during the repair. The other causes are examined on the unit.

Voltage spikes, for example from a weak battery or a jump start, can strain the electronics. Cold solder joints and damp plug connections lead to contact problems.

How can you tell that the 86250-38080 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and this means that the 86250-38080 has a fault. Add to this an error message in the instrument cluster, a missing connection to the diagnostic tool and a fault memory that cannot be cleared.

The light and the message show that the system has detected a fault, and they should be taken seriously.

In that case, airbags and seatbelt pretensioners may not deploy in an emergency.
