Airbag control unit with part number 86250-36561

What does the airbag control unit 86250-36561 do?

The airbag control unit 86250-36561 controls the restraint system (SRS) in SsangYong. It evaluates the crash sensors, determines in a crash which airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

Faults are reported via the airbag warning light in the instrument cluster. In a crash, the decision has to be made within milliseconds.

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

Why does the control unit 86250-36561 fail?

Stored crash data from an accident is the most common cause with the control unit 86250-36561, even when no airbag has fired. Other causes include aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

A standard diagnostic tool cannot remove this crash data. Airbag24 erases it during the repair.

Voltage spikes occur, for example, with a weak battery or when jump-starting. Such voltage spikes place additional strain on the electronics.

How can you tell that the 86250-36561 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently. In addition, an error message may appear, the diagnostic tool may fail to connect to the control unit, or the fault memory cannot be cleared. Such signs point to a defect in the 86250-36561.

As long as the fault persists, airbags and seatbelt pretensioners may not trigger in an emergency, so a prompt check is advisable.

The fault memory, which a specialist workshop or you can have read out with a diagnostic tool, shows whether the control unit or only a wire is affected.
