Airbag control unit with part number 68303594AD

What does the airbag control unit 68303594AD do?

The unit 68303594AD is the SRS control unit of Dodge, that is, the central control unit of the restraint system. It evaluates sensor signals, decides in a crash within milliseconds whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

If the system detects a fault, it reports it via the airbag warning light.

After an accident the control unit stores crash data and locks itself.

Why does the control unit 68303594AD fail?

Stored crash data from an accident is the most common cause, even if no airbag was triggered. A normal diagnostic tool cannot erase this data. Aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes are also possible causes.

Which of these causes affects the individual unit, and how strongly, is shown by the fault memory that is read out.

Voltage spikes arise, for example, when the battery is weak or a jump start was needed. Cold solder joints and moisture on the contacts can cause connection problems.

How can you tell that the 68303594AD is defective?

Typical signs are an airbag warning light that is lit permanently or intermittently, a fault message in the instrument cluster, a diagnostic tool without connection to the control unit, and a fault memory that cannot be cleared.

If you notice one of these signs, a check of the restraint system is advisable. In an emergency, airbags and seatbelt pretensioners may not trigger.

The cable or plug can also be the cause.
