Airbag control unit with part number 15796967

What does the airbag control unit 15796967 do?

For Chevrolet, the airbag control unit 15796967 manages the triggering of airbags and seatbelt pretensioners. In a crash it evaluates the crash sensors and decides within an instant whether to trigger. At the same time it checks the system continuously.

The monitoring runs in the background. If it finds a fault, the instrument cluster displays it via the airbag warning light.

After an accident the unit stores crash data and locks itself.

Why does the control unit 15796967 fail?

Crash data from an earlier accident is considered the most common cause, even without a deployed airbag; it cannot be erased with a normal diagnostic tool. Ageing components, moisture and voltage spikes also play a role.

Crash data is therefore the first point the read-out clarifies.

The other triggers develop more gradually: electronic components age, solder joints can be cold, and moisture attacks plug connections. A voltage spike, for example from a weak battery, can also damage the unit.

Whether any of these causes applies is shown only by the fault memory log.

How can you tell that the 15796967 is defective?

The airbag warning light in the instrument cluster lights up constantly or only intermittently. Further signs point to a defect as well. In an emergency, airbags and seatbelt pretensioners may then not be able to trigger.

• Fault message in the instrument cluster
• Diagnostic tool without a connection to the control unit
• Fault memory that cannot be cleared

The warning light shows the defect as soon as the control unit detects it.

Whether the control unit or the wiring is the cause is clarified only by the diagnosis.
