Airbag control unit with part number 86250-34010

What does the airbag control unit 86250-34010 do?

The airbag control unit 86250-34010 is the control centre of the restraint system (SRS) in SsangYong. It checks the signals from the crash sensors and decides in an accident within milliseconds which airbags and seatbelt pretensioners are triggered. After a crash it stores crash data and locks itself.

During operation the unit monitors the entire restraint system continuously. If it detects a fault, it shows this via the airbag warning light in the instrument cluster, together with an error message.

This way the state of the system stays visible to the driver at all times, without the driver having to start a check.

Why does the control unit 86250-34010 fail?

The most common cause is crash data stored after an accident, even if no airbag was deployed; a normal diagnostic tool cannot erase it. Other possible causes are aged electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes, for example from a weak battery or when a jump start is used.

The data is stored even when an accident turned out mildly and no airbag was triggered. That is why an accident without deployment is no sign that the unit has remained undamaged.

Which cause applies in an individual case only the examination of the unit shows. Components and connections can hardly be judged from the outside.

How can you tell that the 86250-34010 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and an error message appears in the instrument cluster. The diagnostic tool cannot connect to the control unit, and the fault memory cannot be cleared.

These signs can occur singly or together. A defect in the control unit can therefore make itself noticed in more than one way, and each of these indications deserves a check.

As long as the control unit is disturbed, the airbags and seatbelt pretensioners may not deploy in an emergency. For that reason do not ignore the light, even if the car continues to drive.

On the one hand, compare the part number on the label of the removed unit with this page; this only ensures that it is the right unit. On the other hand, have the fault memory read out beforehand, because only this result shows whether the control unit is defective or whether a plug or cable is the cause.
