Airbag control unit with part number 6S6T-14B056-LC

What does the airbag control unit 6S6T-14B056-LC do?

The control unit 6S6T-14B056-LC is the central control unit of the restraint system (SRS) for Ford. It evaluates the signals from the crash sensors and decides in an accident within milliseconds which airbags and seatbelt pretensioners are triggered.

While driving, the unit monitors the entire system without interruption. If it detects a fault, it shows this via the airbag warning light in the instrument cluster.

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

Why does the control unit 6S6T-14B056-LC fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. A normal diagnostic tool cannot erase them. Other causes include ageing electronic components, cold solder joints, moisture and corrosion on plug connectors, and voltage spikes.

Crash data remain stored in the control unit after an accident, even when no external damage is visible. Removing them is therefore part of the repair at Airbag24 and cannot be done on the side.

The other causes concern the electronics and their surroundings. Components age over time, solder joints can become cold, and moisture can cause corrosion on plugs. Voltage spikes arise, for example, with a weak battery or when a jump start is connected.

How can you tell that the 6S6T-14B056-LC is defective?

A defect shows up through the airbag warning light in the instrument cluster, which lights up permanently or intermittently. In addition there may be a fault message on the display, the diagnostic tool may have no connection to control unit 6S6T-14B056-LC, and a fault memory that cannot be cleared. In that case airbags and seatbelt pretensioners may not deploy in an emergency.

The light is the visible message that the system has detected a fault. A glance at the instrument cluster is therefore enough to establish the condition.

Have a fault investigated promptly, even if the car drives normally in everyday use. The diagnostic tool is the first step before you change anything on the unit itself.
