Airbag control unit with part number 86250-34541

What does the airbag control unit 86250-34541 do?

The airbag control unit 86250-34541 controls the restraint system (SRS) of SsangYong. It evaluates the signals from the crash sensors, triggers the appropriate airbags and seatbelt pretensioners in the event of an accident, and monitors the system continuously. After an accident, it stores crash data and locks itself.

The housing also carries the manufacturer number Continental A2C85905200.

The triggering decision must be made within milliseconds. To this end, the unit constantly checks its connections and circuits during operation and reports faults via the airbag warning light in the instrument cluster.

Why does the control unit 86250-34541 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed; an ordinary diagnostic tool cannot delete it. In addition, aged electronic components, cold solder joints, moisture and corrosion at plug connections, as well as voltage spikes, for example from a weak battery or jump-starting, come into consideration.

The unit itself creates crash data and keeps it until it is deleted. Airbag24 deletes it during the repair.

The other causes mainly concern the electronics. Components age, solder joints can break, and moisture attacks the contacts at plug connections. How this affects the unit in an individual case only becomes clear during the examination.

How can you tell that the 86250-34541 is defective?

A defect in the 86250-34541 shows itself through the airbag warning light in the instrument cluster, which is on permanently or intermittently, through fault messages in the instrument cluster, through a lack of contact from the diagnostic tool to the control unit, and through a fault memory that cannot be cleared.

The typical signs at a glance:

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

In such a case, airbags and seatbelt pretensioners may possibly not trigger in an emergency. The warning light is therefore not a trivial matter but a reason to act promptly.

Compare the part number on the label of the removed unit with this page, which ensures that you have the right unit. Also have the fault memory read out before you remove the control unit, because only the log shows whether the control unit is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 86250-34140, 86250-34180, 86250-34580, 86250-34780, 8625034540.

How does the repair of the 86250-34541 work?

First have the fault memory read out and enclose the log. Then disconnect the battery, and only then remove the control unit. Next, create a repair order online and send in the well-packed unit. Airbag24 generally needs 3–4 working days to process the unit.

After removal, pack the control unit carefully, enclose the repair order and send it in.

At Airbag24, the unit is examined on the test bench, defective components are replaced, stored crash data is deleted, and a function test is carried out. The unit then returns to you.

Our repairs come with 2 years' statutory liability for defects.

The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.

How does the control unit 86250-34541 get to Airbag24?

You send the control unit 86250-34541 as a parcel or book a UPS collection for an extra charge. After the repair, Airbag24 returns it by UPS. Put the printed repair order into the parcel and pack the unit shockproof.

Fill the box with enough padding material so that the unit does not knock against the walls during transport.
