Airbag control unit with part number YWC105230

What does the airbag control unit YWC105230 do?

The airbag control unit YWC105230 coordinates the SRS restraint system in MG vehicles. It reads the crash sensors, determines within split seconds which airbags and seatbelt pretensioners are triggered, and checks the system constantly.

It reports faults it finds via the airbag warning light. After an accident it stores crash data, and in this state it is locked.

Why does the control unit YWC105230 fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered. A diagnostic tool does not erase it; Airbag24 removes it during the repair. Aged electronics, moist or corroded plug connectors, cold solder joints and voltage spikes also play a role.

Cold solder joints can cause contact problems, and moisture attacks the contacts over time. Voltage spikes occur, for example, with a weak battery or a jump start. Which cause applies in an individual case is only clarified by the test.

How can you tell that the YWC105230 is defective?

Defects on the YWC105230 are noticeable from the airbag warning light that burns permanently or intermittently, from error messages in the instrument cluster, from a missing connection to the diagnostic tool, or from a fault memory that cannot be erased. Then a test is advisable.

Specifically, these points stand out:

• airbag warning light permanently or intermittently on
• error message in the instrument cluster
• diagnostic tool without a connection to the control unit
• fault memory cannot be erased

In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

• MG F 1st generation (1995-2002)
• MG TF (2002-2011)

A comparison of the part number on the label with this page confirms that you have the right unit, nothing more. Therefore have the fault memory read out beforehand, because only it shows whether the control unit or a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers YWC001600.

How does the repair of the YWC105230 work?

Have the fault memory read out first and enclose the printout. Then disconnect the battery and remove the YWC105230. You create a repair order online and send in the well-packed unit. Airbag24 needs 3–4 working days to process it as a rule.

There, the unit is examined on the test bench, defective components are replaced, the crash data is removed and a function test is carried out. Afterwards, your own unit is returned.

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 YWC105230 get to Airbag24?

You send the YWC105230 as a parcel or book a UPS collection for an extra charge. Airbag24 sends it back to you by UPS after the repair.

Print out the repair order and put it in the parcel. Pad the unit shock-proof.
