Airbag control unit with part number 13588099

What does the airbag control unit 13588099 do?

The airbag control unit 13588099 controls the restraint system (SRS) of Chevrolet. In an accident it calculates within milliseconds which airbags and seatbelt pretensioners will fire, and the system is monitored continuously in operation. After an accident it stores crash data and locks itself.

If the electronics detect a fault, they show it via the airbag warning light in the instrument cluster.

It works with a network of sensors and wires whose condition it monitors.

Why does the control unit 13588099 fail?

The most common cause is crash data that stays stored after an accident, even without an airbag deployment. Further causes are aged electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

• Ageing of components in the electronics
• Cold solder joints on the circuit board
• Corrosion and moisture at plugs
• Voltage spikes, for example when starting with external power

A standard diagnostic tool cannot remove the entry from memory. Which cause is actually present is shown only by reading out the fault memory.

How can you tell that the 13588099 is defective?

A defect manifests itself as the airbag warning light and as the error message in the instrument cluster. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

These signs occur together or individually:

• Airbag warning light on constantly or at times
• Error message in the instrument cluster
• Diagnostic tool does not find the control unit
• Fault memory cannot be cleared

The light checks its function after the ignition is switched on. If it stays on afterwards, have the fault memory read out.

Cable breaks or plug problems can also show these signs. Only the readout makes the difference visible.
