Airbag control unit with part number 96818877

What does the airbag control unit 96818877 do?

For Daewoo and Chevrolet, the airbag control unit 96818877 works as the control unit of the restraint system (SRS). In an accident, it uses the crash sensors to decide which airbags and seatbelt pretensioners are triggered. If it detects a fault, it shows this via the airbag warning light.

This evaluation runs continuously, because the decision has only a short time. The connections to sensors and seatbelt pretensioners are monitored as well.

After an accident, the unit stores crash data and locks itself. The following sections explain causes, recognition and the process.

Why does the control unit 96818877 fail?

Stored crash data from an accident is the most common cause, even without airbag deployment. A normal diagnostic tool cannot remove it. Further causes are ageing electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Airbag24 removes the crash data during the repair.

Further causes at a glance:

• ageing of the electronic components
• solder joints that may be cold
• moisture or corrosion at plug connections
• voltage spikes from a weak battery or jump-starting

Which cause is present in an individual case is established by the examination.

How can you tell that the 96818877 is defective?

The airbag warning light, which lights up permanently or intermittently in the instrument cluster, is the most important sign. Fault messages in the instrument cluster, no connection for the diagnostic tool and a fault memory that cannot be cleared also come into play. In an emergency, airbags and seatbelt pretensioners may therefore fail to deploy.

The light warns of a fault in the restraint system, so it must not be overlooked.

A check of the fault memory shows which fault is present.
