Airbag control unit with part number YWJ000241

What does the airbag control unit YWJ000241 do?

The airbag control unit YWJ000241 is the central control unit of the restraint system for MG. It evaluates the crash sensors, decides in a crash within milliseconds on the triggering of airbags and seatbelt pretensioners, and monitors the system continuously. After an accident it stores crash data and locks itself.

Monitoring runs in the background even when everything seems normal. If the unit reports a fault, it appears via the airbag warning light in the instrument cluster.

Why does the control unit YWJ000241 fail?

The most common cause on the YWJ000241 is crash data that stays stored after an accident, even without an airbag having deployed. A normal diagnostic tool cannot erase it. In addition, ageing electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes from weak batteries or jump-starting come into question.

Crash data is not wear, but entries in the memory of the unit.

The other causes develop over time. Solder joints can go cold, plug connections take up moisture, and the electronics age.

How can you tell that the YWJ000241 is defective?

A defect on the YWJ000241 manifests itself through the airbag warning light, which lights up permanently or intermittently, and through fault messages in the instrument cluster. If no connection to the control unit can be established, or the fault memory cannot be cleared, that is also an indication.

• Airbag warning light, permanently or intermittently
• Fault message in the instrument cluster
• No connection established by the diagnostic tool
• Fault memory cannot be cleared

With these signs, the airbags and seatbelt pretensioners may not be able to deploy in an emergency. Have the system checked promptly.

Comparing the part number on the label with this page only confirms that you have the right unit. It does not clarify the cause. Have the fault memory read out beforehand; the log shows whether the control unit or a plug or cable is affected.

For the same vehicles, we also repair control units with the part numbers YWC001171, YWC107010.

How does the repair of the YWJ000241 work?

For the YWJ000241, everything begins with reading out the fault memory, and you enclose its 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 usually needs 3–4 working days for testing, repair and function test.

On the test bench, Airbag24 checks the unit, eliminates defects in components, deletes the crash data and tests the function. Afterwards you get your own unit back.

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 YWJ000241 get to Airbag24?

You send the control unit YWJ000241 as a parcel, or book a UPS collection for an extra charge. Airbag24 returns it by UPS after the repair. The printed repair order goes into the parcel, and you pack the unit shock-proof.

Sturdy packaging ensures that the electronics survive the transport intact.
