Airbag control unit with part number 10457099

What does the airbag control unit 10457099 do?

The airbag control unit 10457099 runs the restraint system (SRS) in vehicles from MG. It reads the crash sensors, decides in a crash within milliseconds on the triggering of airbags and seatbelt pretensioners, and monitors the entire system. After an accident it stores crash data and locks itself.

Monitoring never stops, even if you notice nothing of it. If the unit detects a fault, it appears via the airbag warning light.

Why does the control unit 10457099 fail?

The most common cause on the 10457099 is stored crash data, even when no airbag has deployed; a normal diagnostic tool does not make it disappear. Other factors include ageing electronic components, cold solder joints, moisture and corrosion on plug connections, as well as voltage spikes from a weak battery or jump-starting.

Crash data sits in the control unit and cannot be removed with common tools. The other causes act on the electronics through everyday use.

How can you tell that the 10457099 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and a fault message appears there. The diagnostic tool finds no connection to the 10457099, and the fault memory cannot be cleared.

If these signs appear, the airbags and seatbelt pretensioners may not be able to deploy in an emergency. The light shows the finding clearly, so have the system checked promptly.
