Airbag control unit with part number 10104458/01

What does the airbag control unit 10104458/01 do?

The airbag control unit 10104458/01 belongs to the restraint system (SRS) in MG. It evaluates the signals from the crash sensors and decides in an accident which airbags and seatbelt pretensioners are triggered. It also monitors the system continuously.

The unit shows faults via the airbag warning light in the instrument cluster, so that you receive a warning.

After an accident, it stores crash data and locks itself. Only a repair releases the lock again.

Why does the control unit 10104458/01 fail?

Stored crash data after an accident is the most common cause, even if no airbag has deployed. Other causes are aged electronic components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes, for example with a weak battery or a jump start.

Crash data does not disappear by simply reading it out; it is removed only during the repair at Airbag24. The 10104458/01 is therefore examined specifically on the test bench.

The other causes act in different ways. Ageing and moisture attack slowly, while voltage spikes occur suddenly, for example during a jump start.

How can you tell that the 10104458/01 is defective?

The airbag warning light in the instrument cluster lights up constantly or intermittently and indicates a defect in the 10104458/01. A fault message may be added, as may a diagnostic tool without a connection to the control unit. The fault memory then cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may not deploy. A defect that the warning light reports should therefore be checked promptly.
