Airbag control unit with part number 68480710AC

What does the airbag control unit 68480710AC do?

The airbag control unit 68480710AC is the central control unit of the restraint system (SRS) of Chrysler. It evaluates the signals from the crash sensors, decides in the event of an accident within milliseconds whether to trigger airbags and seatbelt pretensioners, and monitors the system continuously. It reports faults via the airbag warning light.

In everyday use, the control unit works unnoticed in the background. It continuously checks the connections to the sensors and the triggering elements, and if it detects a deviation, it creates an entry in the fault memory, which a diagnostic tool reads out later.

After an accident, the unit stores crash data and locks itself. The warning light and the fault memory are the most important indicators of the condition of the system.

Why does the control unit 68480710AC fail?

Stored crash data after an accident is the most common cause, even if no airbag was triggered; a normal diagnostic tool cannot erase it. Other causes include aged electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes, for example from a weak battery or a jump start.

The crash data stays in the unit until it is erased during the repair.

The other causes tend to develop gradually, for example when a solder joint gives way under vibration or moisture gets into a plug over a long period. Voltage spikes, by contrast, occur suddenly, for example when a jump start is connected.

How can you tell that the 68480710AC is defective?

Typical signs are an airbag warning light in the instrument cluster that stays on permanently or flickers, and an error message there. In addition, a diagnostic tool cannot connect to the control unit, and the fault memory cannot be cleared.

With such a finding, airbags and seatbelt pretensioners may not trigger in an emergency. That is why you should take the warning seriously and not wait until your next workshop appointment.

The warning light is the first place where the fault shows. A look at the instrument cluster after switching on the ignition is enough to spot it, even without a diagnostic tool.

On the one hand, it is worth comparing the part number on the label of the removed unit with this page. This only confirms that it is the correct unit. On the other hand, have the fault memory read out before removing the control unit; the result shows whether the control unit itself is defective or whether a plug or a cable is the cause.
