Airbag control unit with part number 86250-35143

What does the airbag control unit 86250-35143 do?

The airbag control unit 86250-35143 is the central control unit of the restraint system (SRS) for SsangYong. It evaluates the signals of the crash sensors, decides on triggering in a collision and monitors the system continuously.

Detected faults are shown via the airbag warning light in the instrument cluster.

If an accident has happened, the control unit stores crash data and remains locked until the repair lifts the lock.

Why does the control unit 86250-35143 fail?

Crash data from an accident is the most common cause, even if no airbag was triggered, and a standard diagnostic tool cannot erase it from the 86250-35143. Other causes include aged electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes.

The crash data arises regardless of whether there is visible damage to the vehicle.

The remaining causes are generally known: electronics age, solder joints can be cold, moisture attacks contacts, and voltage spikes occur, for example, with a weak battery or when connected to jump-start cables.

How can you tell that the 86250-35143 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 gets no connection to the control unit 86250-35143, and the fault memory cannot be cleared.

These signs mean that airbags and seatbelt pretensioners may not trigger in an emergency.

The warning light shows the defect as soon as it is present.
