Airbag control unit with part number 86250-35153

What does the airbag control unit 86250-35153 do?

The airbag control unit 86250-35153 is the SRS control unit of SsangYong. It evaluates the crash sensors, determines within milliseconds which airbags and seatbelt pretensioners fire, and monitors the entire system. Faults are shown via the airbag warning light.

The control unit works in the background and continuously checks sensors, wiring and actuators for irregularities.

After an accident it stores crash data and then locks itself.

Why does the control unit 86250-35153 fail?

Most often the cause is crash data stored after an accident, even if no airbag has been triggered; a normal diagnostic tool cannot erase it. Aged electronic components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes are also among the causes.

The crash data stays stored until the repair removes it. Common tools cannot reach it.

The other triggers act gradually: electronics age, solder joints go cold, moisture attacks plug contacts.

Voltage spikes also belong here. A weak battery or jump-starting can cause them.

How can you tell that the 86250-35153 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and fault messages appear. In an emergency, airbags and seatbelt pretensioners may fail to deploy. Connection problems with the diagnostic tool are also a sign.

• Airbag warning light lights up permanently or intermittently
• Fault message in the instrument cluster
• Diagnostic tool finds no connection to the control unit
• Fault memory cannot be cleared

The light is the clearest warning signal. Do not ignore such a warning sign, because it shows that the system is disturbed.
