Airbag control unit with part number 68371578AB

What does the airbag control unit 68371578AB do?

The airbag control unit 68371578AB coordinates the restraint system (SRS) in vehicles of Dodge. It checks the signals from the crash sensors and decides in an accident which airbags and seatbelt pretensioners are triggered.

It monitors the entire system continuously. It indicates a detected fault via the airbag warning light, and after an accident it stores crash data and locks itself.

Why does the control unit 68371578AB fail?

Stored crash data from an accident is the most common cause, even if no airbag has triggered; a normal diagnostic tool does not remove it. Other causes are ageing components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

The crash data is created by the accident itself. An airbag having triggered is not a prerequisite for it.

Electronic components age over time, and solder joints can become cold or brittle. Moisture and corrosion attack the contacts, so signal transmission can be disrupted.

Voltage spikes arise, for example, from a weak battery or when starting with jump-start cables, and then affect the control unit.

How can you tell that the 68371578AB is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently. This is accompanied by an error message in the instrument cluster, the diagnostic tool finds no connection to the control unit, and the fault memory cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may then possibly not trigger, which is why the warning must be taken seriously.

A light that comes on only intermittently should also be checked promptly.
