Airbag control unit with part number 13505714

What does the airbag control unit 13505714 do?

The airbag control unit 13505714 manages the restraint system (SRS) of Chevrolet. In an accident it checks the crash sensors and selects, within milliseconds, which airbags and seatbelt pretensioners fire. During operation it monitors the system and reports faults via the airbag warning light.

After an accident the unit stores crash data and locks itself. This lock is part of how this control unit works.

Why does the control unit 13505714 fail?

The most common cause lies in crash data stored after an accident, even if no airbag was triggered. Added to this are aged electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage peaks.

The further causes at a glance:

• aged electronic components
• cold solder joints
• moisture and corrosion on the plug connections
• voltage peaks, for example from a weak battery or a jump start

A normal diagnostic tool does not remove the crash data.

How can you tell that the 13505714 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently, an error message appears, the diagnostic tool gets no connection to the control unit, and the fault memory cannot be cleared. Then airbags and seatbelt pretensioners may not fire in an emergency.

These indications can appear as follows:

• a warning light that stays on permanently or intermittently
• a message in the instrument cluster
• a diagnostic tool without connection to the control unit
• a fault memory that remains

The light shows the fault. Do not wait long before checking, because that is exactly what it is there for.
