Airbag control unit with part number 86250-36270

What does the airbag control unit 86250-36270 do?

For SsangYong, the airbag control unit 86250-36270 controls the restraint system (SRS). It processes the signals from the crash sensors, selects in a crash within milliseconds the airbags and seatbelt pretensioners that trigger, and monitors the system continuously. After a crash, it stores crash data and locks itself.

The manufacturer number Continental A2C13682601 is additionally printed on the housing.

The unit indicates faults via the airbag warning light in the instrument cluster.

Why does the control unit 86250-36270 fail?

Stored crash data from an accident is the most common cause on the control unit 86250-36270, even without a triggered airbag. An ordinary diagnostic tool cannot remove these. Further causes are ageing, contact problems at plugs, moisture and voltage spikes.

The further causes in detail are:

• Ageing of the electronics
• Weak solder joints
• Moisture and corrosion at plugs
• Brief voltage spikes in the vehicle electrical system

How can you tell that the 86250-36270 is defective?

The airbag warning light in the instrument cluster indicates a fault on the control unit 86250-36270: it lights up permanently or intermittently. In this state, airbags and seatbelt pretensioners may possibly not trigger.

These signs occur:

• A fault indication in the instrument cluster
• No connection between the diagnostic tool and the control unit
• A fault memory that cannot be reset

Have the fault memory read out as soon as one of these signs appears.
