Airbag control unit with part number 68437716AD

What does the airbag control unit 68437716AD do?

The airbag control unit 68437716AD is the control centre of the restraint system (SRS) at Jeep. It checks the sensors continuously and decides in a crash which airbags and seatbelt pretensioners are triggered. It detects faults itself and shows them via the airbag warning light.

The sensor signals are evaluated so quickly that triggering in an emergency happens without delay. The control unit keeps working without interruption throughout.

After an accident it stores crash data and locks itself.

Why does the control unit 68437716AD fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered. A normal diagnostic tool cannot erase it. Ageing components, cold solder joints, moisture and voltage spikes are also possible causes.

Crash data stays in the memory until it is specifically removed. Airbag24 does this during the repair, so the unit can be checked without this entry.

Electronic components age, and their solder joints can lose contact over time. Moisture and corrosion at plug connectors lead to faulty contacts, which the control unit then reports.

Voltage spikes, for example from a weak battery or jump-starting, also belong to the possible causes.

How can you tell that the 68437716AD is defective?

A permanently or intermittently lit airbag warning light in the instrument cluster is the clearest sign, accompanied by a fault message in the instrument cluster. The diagnostic tool gets no connection to the control unit, and the fault memory cannot be cleared.

If you notice these signs, the airbags and seatbelt pretensioners may fail to trigger in an emergency. The light reports the defect, so it is the indication itself and not merely the check.

How pronounced the signs are does not matter for the decision. The light alone is reason enough to have the system examined.
