Airbag control unit with part number P04672603AG

What does the airbag control unit P04672603AG do?

The airbag control unit P04672603AG controls the restraint system (SRS) for Dodge. It evaluates the crash sensors, decides in an accident, within milliseconds, which airbags and seatbelt pretensioners are triggered, and checks the system for faults continuously.

Faults are reported via the airbag warning light. After an accident, the unit stores crash data and locks itself; the lock is only lifted by the repair.

During normal driving, the control unit remains unobtrusive in the background. It is usually only noticed when a warning appears in the instrument cluster.

Why does the control unit P04672603AG fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. Further causes in brief:

Crash data remains in the memory even if the vehicle drives normally again. A normal diagnostic tool cannot erase it, so the system continues to report a fault. Airbag24 erases the crash data during the repair.

The other causes are:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connectors
• voltage spikes, for example from a weak battery or jump-starting

How can you tell that the P04672603AG is defective?

Typical signs are the airbag warning light in the instrument cluster, which stays on permanently or intermittently, an error message in the instrument cluster, a missing connection between the diagnostic tool and the control unit, and a fault memory that cannot be cleared.

• The airbag warning light stays on permanently or intermittently.
• An error message appears in the instrument cluster.
• The diagnostic tool finds no connection to the control unit.
• The fault memory cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may fail to deploy. The warning light indicates the defect, so you should follow up on the warning.
