Airbag control unit with part number 68226174AE

What does the airbag control unit 68226174AE do?

The airbag control unit 68226174AE coordinates the restraint system (SRS) of Dodge. It reads the signals from the crash sensors, determines in an accident within milliseconds which airbags and seatbelt pretensioners fire, and checks the system continuously. After an accident it stores crash data and locks itself.

Diagnostics run in the background, and the unit passes faults on via the airbag warning light in the instrument cluster.

Because triggering takes only milliseconds, the control unit must work flawlessly at all times.

Why does the control unit 68226174AE fail?

Stored crash data after an accident is the most common cause with the 68226174AE, even if no airbag has deployed. Further causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

The crash data stays in the control unit, because a normal diagnostic tool cannot remove it. The problem therefore persists until the unit is repaired.

The other causes relate to ageing and the environment. Electronic components lose stability over time, cold solder joints can interrupt contacts, and moisture together with corrosion impairs plug connections. Voltage spikes, as occur with a weak battery or a jump start, can also harm the unit.

How can you tell that the 68226174AE is defective?

A defect in the 68226174AE can be recognised by the airbag warning light in the instrument cluster, which lights up permanently or intermittently. Added to that are a fault message, no connection established by the diagnostic tool, and a fault memory that cannot be cleared.

With any one of these signs, airbags and seatbelt pretensioners may not deploy in an emergency. The warning light is the clearest indication, because it reports a fault in the restraint system directly.

Even if the display only appears briefly, a check is worthwhile.

Which vehicles is the 68226174AE fitted in?
