Airbag control unit with part number 68437715AD

What does the airbag control unit 68437715AD do?

The airbag control unit 68437715AD is the central control unit of the restraint system for Jeep. It processes the signals from the impact sensors and decides in a crash, within milliseconds, whether the airbags and seatbelt pretensioners are triggered.

The system is monitored continuously, and faults are reported via the airbag warning light in the instrument cluster.

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

Why does the control unit 68437715AD fail?

Stored crash data is the most common cause on the 68437715AD, even if no airbag has triggered. A normal diagnostic tool cannot delete this data; Airbag24 removes it during the repair. Other possible causes are aged components, cold solder joints, moisture at plug connectors and voltage spikes.

Crash data stays in the memory even when nothing conspicuous shows on the vehicle. It is therefore a finding that only diagnosis makes reliably visible.

The remaining causes concern the electronics. Components age, solder joints can go cold, and moisture causes corrosion in plugs. Voltage spikes, for example from a weak battery or jump-starting, also place a load on the unit.

How can you tell that the 68437715AD is defective?

On the 68437715AD, a defect shows through the airbag warning light in the instrument cluster, which stays on permanently or intermittently. In addition, a fault message appears in the instrument cluster, the diagnostic tool gets no connection to the control unit, and a fault memory that cannot be cleared is also a sign.

In an emergency, airbags and seatbelt pretensioners may then fail to trigger. A check is therefore advisable as soon as the warning light comes on.
