Airbag control unit with part number 13587444

What does the airbag control unit 13587444 do?

The airbag control unit 13587444 controls the restraint system (SRS) for Chevrolet. In a crash it evaluates the signals from the crash sensors and determines which airbags and seatbelt pretensioners are triggered. After an accident it stores crash data and locks itself.

During operation it monitors all components of the system. If it detects a fault, the airbag warning light in the instrument cluster comes on.

In an emergency the evaluation has to succeed within a very short time, which is why the control unit is firmly integrated into the safety architecture.

Why does the control unit 13587444 fail?

The most common cause is a memory entry: crash data stored after an accident, even if no airbag was triggered. A normal diagnostic tool does not erase this data; during repair, Airbag24 erases it. Aged components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes also play a role.

Several other influences may also come into consideration:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connectors
• voltage spikes, for example from a weak battery or jump starting

Only testing the electronics shows which of these causes is actually present.

How can you tell that the 13587444 is defective?

The airbag warning light in the instrument cluster indicates the defect, either permanently or intermittently. There are also other signs that point to a malfunction.

• airbag warning light permanently on
• airbag warning light intermittently on
• fault message in the instrument cluster
• diagnostic tool has no connection to the control unit
• fault memory cannot be cleared

If you see any of these indications, the airbags and seatbelt pretensioners may not trigger in an emergency.

In this case, a prompt check of the system is the right step.
