Airbag control unit with part number P68147712AA

What does the airbag control unit P68147712AA do?

The airbag control unit P68147712AA is the central control unit of the restraint system (SRS) of Dodge. It evaluates the signals from the crash sensors, decides in an accident within milliseconds whether airbags and seatbelt pretensioners are triggered, and monitors the system permanently.

If it detects a fault, the airbag warning light comes on. After an accident, the unit records crash data and is then locked.

Why does the control unit P68147712AA fail?

The most common cause is crash data stored in the unit after an accident, even if no airbag has triggered. A normal diagnostic tool cannot remove them from memory. In addition, aged electronic components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes can be the cause.

The memory keeps the data even when the vehicle drives normally again afterwards.

The other causes develop gradually. Electronics age, solder joints lose their hold over the years, and moisture attacks plug contacts. Voltage spikes, for example from a weak battery or a jump start, additionally stress the circuit.

How can you tell that the P68147712AA is defective?

The airbag warning light in the instrument cluster burns or flickers, a fault message appears in the instrument cluster, the diagnostic tool cannot reach the control unit, or the fault memory cannot be erased. Then airbags and seatbelt pretensioners may not trigger in an emergency.

The warning light reports the fault itself, which makes it the most important sign. Have the system checked promptly, because in an emergency airbags and seatbelt pretensioners may not trigger.
