Airbag control unit with part number 68492237AD

What does the airbag control unit 68492237AD do?

The airbag control unit 68492237AD is the central control of the restraint system (SRS) in Dodge. It evaluates the crash sensors and decides in a crash, within milliseconds, which airbags and seatbelt pretensioners to trigger.

It monitors the system continuously, and faults appear via the airbag warning light.

After a crash, the unit stores crash data and locks itself.

Why does the control unit 68492237AD fail?

After a crash, stored crash data is the most common cause in the 68492237AD, even if no airbag has deployed. A normal diagnostic tool cannot erase it. Other causes include aged electronics, cold solder joints, moisture and corrosion, and voltage spikes.

The crash data sits in the unit itself, independent of plugs and cables.

Ageing, moisture and corrosion attack the components, and voltage spikes from a weak battery or a jump start put additional strain on the electronics.

How can you tell that the 68492237AD is defective?

The airbag warning light lights up permanently or intermittently when the 68492237AD has a fault. Accompanying signs are an error message in the instrument cluster, no connection to the diagnostic tool, and a fault memory that cannot be cleared.

Such a fault means that the airbags and seatbelt pretensioners may not deploy in an emergency.

The instrument cluster shows the warning clearly, so have the condition checked promptly.
