Airbag control unit with part number P04672603AH

What does the airbag control unit P04672603AH do?

The airbag control unit P04672603AH runs the restraint system (SRS) of Dodge. It captures the signals of the crash sensors, decides in an accident which airbags and seatbelt pretensioners are triggered, and shows faults via the airbag warning light.

It monitors the system continuously. After an accident, it stores crash data and locks itself.

The processes inside the unit remain invisible to the driver until a message appears.

Why does the control unit P04672603AH fail?

With the P04672603AH, the most common cause is stored crash data after an accident, even if no airbag has deployed. A normal diagnostic tool cannot delete it. Aged electronic components, cold solder joints, moisture and corrosion at plug connections, as well as voltage spikes, are also possible causes.

Crash data is deleted by Airbag24 during the repair; this step is a firm part of the process.

The other causes arise generally over a longer period. Electronics age, solder joints become brittle, and moisture and rust settle on the contacts. A voltage spike, for example from a weak battery or a jump start, can also impair the electronics.

How can you tell that the P04672603AH is defective?

A defect on the P04672603AH shows up as the airbag warning light in the instrument cluster, which either lights up permanently or flashes intermittently. In addition, there are fault messages in the instrument cluster, no connection of the diagnostic tool, and a fault memory that cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

The warning light has the task of reporting exactly such faults.

A fault memory that cannot be reset fits this picture and calls for a check.
