Airbag control unit with part number 68226172AD

What does the airbag control unit 68226172AD do?

The airbag control unit 68226172AD controls the restraint system of Dodge. In the event of a crash, it checks the sensor signals within milliseconds and triggers the appropriate airbags and seatbelt pretensioners.

In the background, it monitors the system permanently and shows faults via the airbag warning light in the instrument cluster.

If an accident has occurred, the unit stores crash data and then locks itself.

Why does the control unit 68226172AD fail?

The most common cause of the 68226172AD failing is crash data stored after an accident, even if no airbag was deployed. A usual diagnostic tool cannot remove this data. Aged components, cold solder joints, moisture and corrosion, as well as voltage spikes, are also possible causes.

Aged electronic components lose reliability over time. On plug connections, moisture and corrosion can disrupt contacts.

Voltage spikes, for example from a weak battery or a jump start, can also affect the control unit.

How can you tell that the 68226172AD is defective?

A defect in the 68226172AD shows up mainly in the instrument cluster. The unit also signals a fault if the diagnostic tool cannot make contact.

• Airbag warning light is on permanently or intermittently
• Fault message in the instrument cluster
• Diagnostic tool receives no connection to the control unit
• Fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may then fail to deploy.
