Airbag control unit with part number 13507217

What does the airbag control unit 13507217 do?

The airbag control unit 13507217 coordinates the restraint system (SRS) of Chevrolet. From the signals of the crash sensors it works out, within a fraction of a second in an accident, which airbags and seatbelt pretensioners are triggered. After an accident it stores crash data and locks itself.

During operation it monitors the entire system: wiring, sensors and firing circuits are checked continuously. If it detects a fault, it reports it via the airbag warning light in the instrument cluster.

Why does the control unit 13507217 fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered; a normal diagnostic tool cannot erase it. Other causes include ageing electronic components, cold solder joints, moisture and corrosion at connectors, and voltage spikes.

The crash data remains in the unit after the accident is over. The fact that no airbag fired changes nothing, because the control unit still records the event. Further failures arise from the ageing of the electronics, faulty solder joints on the circuit board, moisture or corrosion at plug connections, and voltage spikes, for example from a weak battery or a jump start.

How can you tell that the 13507217 is defective?

Typical signs are an airbag warning light that lights up permanently or intermittently, a fault message in the instrument cluster, no connection between the diagnostic tool and the control unit, and a fault memory that cannot be cleared. In these cases, airbags and seatbelt pretensioners may not trigger in an emergency.

The signs at a glance:

• Airbag warning light lights up permanently
• Airbag warning light lights up intermittently
• Fault message in the instrument cluster
• Diagnostic tool receives no connection to the control unit
• Fault memory cannot be cleared

Have the warning checked even if the vehicle otherwise drives normally.
