Airbag control unit with part number 68105510AC

What does the airbag control unit 68105510AC do?

The airbag control unit 68105510AC is the control unit of the restraint system in Chrysler vehicles. From the values of the crash sensors, it works out which airbags and seatbelt pretensioners are triggered in an accident, within a few milliseconds.

The unit also continuously checks the wiring and the connected components. If it detects a fault, the airbag warning light in the instrument cluster lights up.

After an accident, it writes crash data into its memory and then remains locked.

Why does the control unit 68105510AC fail?

The most common cause with the 68105510AC is crash data from an earlier accident, even if no airbag has deployed. A standard diagnostic tool does not remove these entries. Aged electronics, cold solder joints, moisture and corrosion on plug connectors, and voltage spikes are also possible causes.

Even small changes at solder joints or contacts can cause a malfunction. Whether one of them is present must be shown by the inspection.

Airbag24 erases crash data during the repair. Only the examination of the unit can say anything about the other causes.

How can you tell that the 68105510AC is defective?

A defect on the 68105510AC first shows up as the airbag warning light, which burns permanently or intermittently. Fault messages in the instrument cluster, a missing connection to the diagnostic tool or a fault memory that cannot be emptied may also appear. In an emergency, airbags and seatbelt pretensioners may then not deploy.

The warning light is the system's own feedback about itself and shows a fault directly.

A fault memory that cannot be emptied, even after an attempt to clear it, points to a fault that is still present.
