Airbag control unit with part number 68437719AD

What does the airbag control unit 68437719AD do?

The airbag control unit 68437719AD controls the restraint system (SRS) of Jeep. It checks the sensors, determines in a crash which airbags and seatbelt pretensioners trigger, and monitors the system permanently for faults.

The unit indicates faults it has found via the airbag warning light. The sensors are evaluated without any action by the driver.

After a crash, the control unit stores crash data and is then locked.

Why does the control unit 68437719AD fail?

Stored crash data after an accident is the most common cause, even if no airbag has deployed. This data cannot be erased with an ordinary diagnostic tool. Other possible causes are aged components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

The crash data is stored in the unit as soon as it has registered the event. Whether the airbag fired makes no difference to the storage.

The remaining causes lie in the electronics. Components age, solder joints can go cold, and moisture or corrosion disturb the contact in plug connections. Voltage spikes, for example from a weak battery or jump-starting, can also cause problems.

How can you tell that the 68437719AD is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently. An error message appears, the diagnostic tool cannot reach the control unit, and the fault memory cannot be cleared.

The warning light is the first sign of a defect. It shows that the control unit has detected a fault in the restraint system.

As long as the fault persists, airbags and seatbelt pretensioners may possibly fail to deploy in an emergency. Therefore have the system checked promptly.
