Airbag control unit with part number 86250-34640

What does the airbag control unit 86250-34640 do?

As the airbag control unit for SsangYong, the 86250-34640 coordinates the restraint system (SRS). It reads the impact sensors and determines within milliseconds which airbags and seatbelt pretensioners fire in an accident.

The unit monitors the system continuously. It indicates detected faults via the airbag warning light. After an accident, it stores crash data and locks.

The housing also carries the manufacturer's number Continental A2C96188400.

Why does the control unit 86250-34640 fail?

The most common cause in the 86250-34640 is stored crash data from an accident, even without a triggered airbag. An ordinary diagnostic tool cannot erase this data.

The other causes at a glance:

• ageing of the electronic components
• solder joints that become cold or brittle over time
• moisture and corrosion in plug connections
• voltage spikes, for example from a weak battery or jump-starting

The readout of the fault memory shows whether any of these causes applies.

How can you tell that the 86250-34640 is defective?

A defect in the 86250-34640 shows itself when the airbag warning light stays on permanently or intermittently. If a message also appears in the instrument cluster, that confirms the suspicion. In an emergency, the airbags and seatbelt pretensioners may then fail to trigger.

These signs can be noticed:

• airbag warning light stays on constantly or flickers
• warning message on the instrument cluster display
• reading tool does not find the control unit
• entries in the fault memory cannot be removed

Have such an indication checked promptly.
