Airbag control unit with part number 68247732AC

What does the airbag control unit 68247732AC do?

The airbag control unit 68247732AC is the control unit of the restraint system (SRS) for Dodge. It processes the signals from the crash sensors and makes the decision in a crash as to which airbags and seatbelt pretensioners are triggered. Beyond that, it monitors the system continuously.

If the unit detects a fault, it reports it via the airbag warning light in the instrument cluster. The signal is therefore the first visible sign.

After a crash, the unit stores crash data and locks itself. It connects the sensors with the triggering of the restraint devices.

Why does the control unit 68247732AC fail?

Stored crash data from an accident is the most common cause, even if no airbag has deployed. With the control unit 68247732AC, this data cannot be erased with a normal diagnostic tool; Airbag24 erases it during the repair. Other causes are aged electronics, cold solder joints, moisture and corrosion at plug connections, and voltage peaks.

Whether an airbag has deployed does not affect the storage. That is why, after an incident, it is worth thinking of the crash data first.

Aged electronic components and cold solder joints develop over time. Moisture and corrosion impair plug connections and thus the contact within the system.

Voltage peaks, for example from a weak battery or when starting with a jump-start, place additional stress on the control unit.

How can you tell that the 68247732AC is defective?

A defect in the 68247732AC shows up on the airbag warning light, which lights up permanently or intermittently. It is also accompanied by an error message in the instrument cluster. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

• Airbag warning light in the instrument cluster is on permanently or intermittently
• Error message in the instrument cluster
• Diagnostic tool cannot establish a connection to the control unit
• Fault memory cannot be cleared

These signs occur individually or together. Any one of them is reason enough to have the system checked.
