Airbag control unit with part number 86250-35510

What does the airbag control unit 86250-35510 do?

The airbag control unit 86250-35510 forms the central control unit of the restraint system (SRS) of SsangYong. It evaluates the crash sensors, decides within milliseconds in an accident on airbags and seatbelt pretensioners, and monitors the system permanently.

In addition, the manufacturer number Continental A2C89785701 is printed on the housing. The unit stores faults in the fault memory and displays them via the airbag warning light in the instrument cluster.

After an accident the unit stores crash data and locks itself. Only the repair lifts the lock.

Why does the control unit 86250-35510 fail?

Stored crash data from an accident is the most common cause, even if no airbag has deployed; a normal diagnostic tool cannot erase it. Aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes from a weak battery or jump-starting are also possible causes.

Airbag24 removes the crash data during the repair.

Whether any of the other causes applies can only be determined by a test. A supposition alone is not sufficient for that.

How can you tell that the 86250-35510 is defective?

A defect shows itself on the 86250-35510 when the airbag warning light in the instrument cluster lights up, fault messages appear in the instrument cluster, the diagnostic tool does not establish a connection, or the fault memory cannot be cleared.

• Airbag warning light lights up permanently
• Airbag warning light lights up intermittently
• Fault message in the instrument cluster
• No connection between the diagnostic tool and the control unit
• Fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may then possibly fail to deploy. Therefore, take this warning seriously.
