Airbag control unit with part number 96818875

What does the airbag control unit 96818875 do?

For Daewoo and Chevrolet, the airbag control unit 96818875 controls the restraint system (SRS). It processes the signals from the crash sensors, selects the right airbags and seatbelt pretensioners within milliseconds in an accident, and monitors the system continuously. After an accident, it stores crash data and locks itself.

In normal operation, the unit checks the system continuously and reports faults via the airbag warning light in the instrument cluster. This light is the signal that the driver sees in the instrument cluster.

The sensors and the triggering are closely linked, so a fault in the restraint system affects the whole system.

Why does the control unit 96818875 fail?

The most common cause on the 96818875 is stored crash data from an accident, even if no airbag has triggered. Other causes are aged components, moisture and corrosion, and voltage spikes.

• aged electronic components
• cold solder joints on the circuit board
• moisture and corrosion at the plug connections
• voltage spikes, for example with a weak battery or a jump start

A normal diagnostic tool cannot remove the crash data.

Which of the other causes applies in an individual case is clarified by the check on the test bench.

How can you tell that the 96818875 is defective?

A defect on the 96818875 shows at the airbag warning light in the instrument cluster, which lights up permanently or intermittently. A fault message in the instrument cluster, a diagnostic tool without a connection to the control unit, or a fault memory that cannot be cleared also point to a defect.

• instrument cluster warning light is on permanently
• warning light comes on intermittently
• fault message in the instrument cluster
• no connection to the diagnostic tool
• fault memory cannot be cleared

Any one of these signs is reason enough for a check. In an emergency, airbags and seatbelt pretensioners may then be unable to trigger.
