Airbag control unit with part number 86250-36170

What does the airbag control unit 86250-36170 do?

The airbag control unit 86250-36170 manages the restraint system (SRS) in SsangYong vehicles. It evaluates the crash sensors, decides in an accident within milliseconds on the triggering of airbags and seatbelt pretensioners, and monitors the system continuously.

The manufacturer number Continental A2C13582600 is additionally printed on the housing.

The sensors continuously deliver measured values, from which the unit derives the location of an impact. If it detects a fault, it reports it via the airbag warning light. After a crash, it stores crash data and locks itself.

Why does the control unit 86250-36170 fail?

The most common cause is stored crash data after an accident, even without an airbag triggering, which a diagnostic tool cannot erase. Further causes are aged components, cold solder joints, moisture at connectors and voltage spikes.

Crash data are stored in the unit after an accident, and this also applies without an airbag having triggered. A normal diagnostic tool cannot clear them.

Aged electronic components, cold solder joints and moisture at connectors are further sources of faults. Corrosion on the contacts intensifies the problem.

Voltage spikes, for example from a weak battery or jump-starting, additionally stress the electronics. Whether one of these causes is actually present is shown by the inspection.

How can you tell that the 86250-36170 is defective?

The airbag warning light in the instrument cluster, which stays on constantly or intermittently, is the first sign of a defect. Fault messages in the instrument cluster and a diagnostic tool that cannot connect are added. In an emergency, airbags and seatbelt pretensioners may then not trigger.

When the light comes on, have the fault memory read out to see the stored messages.

A fault memory that cannot be cleared is also a finding that needs further clarification.

Typical signs at a glance:

• Airbag warning light constantly on
• Airbag warning light intermittently on
• Fault message in the instrument cluster
• Fault memory cannot be cleared

Which vehicles is the 86250-36170 fitted in?

The control unit 86250-36170 is fitted in these vehicles: SsangYong Rexton Y450 (from 2021) and Y400 (2017-2020). The information comes from the assignment to this part number.

The assignment looks like this:

• SsangYong Rexton Y450 (from 2021)
• SsangYong Rexton Y400 (2017-2020)

Two things matter before you send it in. Compare the part number on the label of the removed unit with this page, because that only confirms that it is the right unit. Also have the fault memory read out, because only that shows whether the control unit itself is defective or a connector or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 86250-38040.

How does the repair of the 86250-36170 work?

First have the fault memory read out and enclose the log, then disconnect the battery before you remove the control unit. Then create a repair order online and send the well-packed unit. At Airbag24, inspection, repair and testing usually take 3–4 working days.

Airbag24 inspects the unit on the test bench, repairs defective components and erases the crash data. The functional test completes the process.

Your own unit then goes back 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 86250-36170 get to Airbag24?

Either you send the control unit as a parcel, or you book a UPS collection for an extra charge. The return after repair is handled by Airbag24 via UPS.

Enclose the printed repair order with the parcel and pack the unit shock-resistant.
