Airbag control unit with part number 13500674

What does the airbag control unit 13500674 do?

The airbag control unit 13500674 controls the restraint system (SRS) at Chevrolet. It analyses the signals from the crash sensors, determines within milliseconds in an accident which airbags and seatbelt pretensioners are triggered, and monitors the entire system. It indicates faults via the airbag warning light.

Between accidents the unit works quietly in the background, checking the connected components.

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

Why does the control unit 13500674 fail?

The most common cause: crash data from an earlier accident, which remains in the control unit 13500674 even if no airbag fired. A normal diagnostic tool does not erase it; Airbag24 removes it during the repair. Other causes arise from operation.

The remaining causes concern ageing and environmental influences. Electronic components age, and moisture or corrosion at plug connectors can disrupt the contact.

• Aged electronic components
• Cold solder joints
• Moisture and corrosion at plug connectors
• Voltage spikes, for example from a weak battery or after a jump start

How can you tell that the 13500674 is defective?

A defect on the 13500674 shows as the airbag warning light in the instrument cluster, lit permanently or intermittently. A fault message in the instrument cluster, a lack of contact with the diagnostic tool or a fault memory that cannot be cleared also indicates a problem.

The light indicates the defect as soon as the system detects it. A diagnostic tool then reads out the fault memory, and its contents are informative.

In an emergency, the airbags and seatbelt pretensioners may not be able to fire as long as the fault persists. Arrange a check promptly.
