Airbag control unit with part number 6S65-14B056-EP

What does the airbag control unit 6S65-14B056-EP do?

The airbag control unit 6S65-14B056-EP coordinates the restraint system (SRS) in the Ford vehicle. It evaluates the crash sensors and decides in an accident which airbags and seatbelt pretensioners are triggered.

The decision is made in milliseconds, so the unit is constantly on standby. In operation it also checks the system and shows faults via the airbag warning light in the instrument cluster.

After an accident it stores crash data and then locks itself.

Why does the control unit 6S65-14B056-EP fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. Further causes at a glance:

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

Crash data cannot be removed with a normal diagnostic tool. The other causes cannot be reliably detected from the outside and only show up in the fault memory.

How can you tell that the 6S65-14B056-EP is defective?

A defect shows itself through the airbag warning light, which lights up permanently or intermittently, and through fault messages. A missing contact to the diagnostic tool and a fault memory that cannot be cleared are also signs.

These signs in detail:

• airbag warning light on permanently or intermittently
• fault message in the instrument cluster
• diagnostic tool receives no connection
• fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may not trigger. Therefore have the finding clarified promptly.
