Airbag control unit with part number YWC001600

What does the airbag control unit YWC001600 do?

The airbag control unit YWC001600 forms the control unit of the restraint system (SRS) in MG. It processes the signals from the crash sensors, decides in an accident whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

The unit registers a fault itself and shows it via the airbag warning light in the instrument cluster. This light is therefore the first indication to you that something is wrong with the system.

After an accident, the unit stores crash data and locks itself. The lock ends only with the repair.

Why does the control unit YWC001600 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. Added to this are aged electronic components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes, for example from a jump start or a weak battery. At Airbag24, the YWC001600 is checked precisely for these points.

Crash data cannot be removed with common diagnostic tools. Airbag24 clears it during the repair.

The other causes concern the electronics themselves or their connections. Ageing works slowly, cold solder joints can interrupt contacts, and moisture causes corrosion on the plugs. Such faults develop gradually.

How can you tell that the YWC001600 is defective?

A defect in the YWC001600 can mainly be recognised by the airbag warning light in the instrument cluster, which lights up constantly or intermittently. This is often accompanied by fault messages or a diagnostic tool without a connection.

• Airbag warning light lights up constantly or intermittently
• Fault message in the instrument cluster
• Diagnostic tool does not establish a connection to the control unit
• Fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may possibly fail to deploy. For this reason, you should have these signs checked promptly.

Which vehicles is the YWC001600 fitted in?

The YWC001600 is fitted in these vehicles: MG F 1st generation (1995-2002).

The vehicles are assigned to this part number as follows:

• MG F 1st generation (1995-2002)

Comparing the part number on the label of the removed unit with this page only confirms that it is the correct unit. The fault memory answers the question about the defect. Have it read out before removal, because it 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 YWC105230.

How does the repair of the YWC001600 work?

First have the fault memory read out and attach the log, then disconnect the battery and only then remove the YWC001600. Next, create a repair order online and send the unit in well packed. Airbag24 needs 3–4 working days in total for testing, repair and function test.

Airbag24 examines the unit on the test bench, repairs defective components, deletes stored crash data and finishes with a function test. Your unit then comes 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 YWC001600 get to Airbag24?

A parcel or a UPS collection for an extra charge brings the YWC001600 to Airbag24. Returns after the repair are sent by UPS.

The printed repair order belongs in the parcel, and the control unit must be packed shock-proof.
