Airbag control unit with part number 68346752AB

What does the airbag control unit 68346752AB do?

The airbag control unit 68346752AB belongs to the restraint system (SRS) of Dodge. In an accident it assesses sensor signals within milliseconds, determines which airbags and seatbelt pretensioners are triggered, and monitors the entire system permanently.

If the electronics detect a fault, they report it via the airbag warning light in the instrument cluster. After an accident the unit stores crash data and locks itself; the lock is lifted only by a repair.

Why does the control unit 68346752AB fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed, and which common diagnostic tools cannot erase. Further causes are aged electronics, cold solder joints, moisture and corrosion, and voltage spikes.

Electronics change over the years, and malfunctions can therefore occur. A unit that has been in use for a long time can therefore fail for this reason.

Cold solder joints as well as moisture and corrosion at plug connections impair the electrical contact. Voltage spikes, for example from a weak battery or jump-starting, additionally stress the electronics.

How can you tell that the 68346752AB is defective?

The airbag warning light in the instrument cluster gives the hint when it lights up at times or constantly. In addition there are fault messages in the instrument cluster, no connection to the diagnostic tool, or a fault memory that cannot be cleared.

As long as these signs persist, airbags and seatbelt pretensioners may fail to deploy in an emergency. The light is therefore no detail that can be ignored.
