Airbag control unit with part number 68358974AB

What does the airbag control unit 68358974AB do?

In Chrysler, the airbag control unit 68358974AB controls the restraint system (SRS). It receives the signals from the crash sensors, decides in an accident within milliseconds which airbags and seatbelt pretensioners are triggered, and monitors the system continuously. It indicates faults via the airbag warning light.

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

While driving, it constantly evaluates measured values.

Why does the control unit 68358974AB fail?

The most common cause is crash data from an accident, even if no airbag has deployed. Further causes are aged components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

These data cannot be removed with a usual diagnostic tool. The remaining causes lie in the electronics and at the connections: components age, cold solder joints are possible, and moisture or corrosion at plugs disrupts the contact.

Voltage spikes, for example from a weak battery or after a jump start, can contribute to the failure. Airbag24 deletes the crash data during the repair.

How can you tell that the 68358974AB is defective?

You recognise a fault by the airbag warning light in the instrument cluster, which stays on permanently or intermittently. In addition there may be a fault message in the instrument cluster, no connection to the diagnostic tool, and a fault memory that cannot be cleared.

While this condition persists, airbags and seatbelt pretensioners may fail to deploy in an emergency. An inspection is therefore sensible, even if the vehicle otherwise runs without any abnormality.

Whether the defect lies in the control unit itself or in the wiring can be clarified through the fault memory.

First read out the fault memory and attach the log. Then disconnect the battery, remove the control unit and create a repair order online. Afterwards send the unit in, well packed.

Airbag24 tests the unit on the test bench, deletes stored crash data, replaces defective components and carries out a function test. Afterwards your own unit comes back to you.

Processing at Airbag24 usually takes 3–4 working days and covers only inspection, repair and testing. Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.

How does the control unit 68358974AB get to Airbag24?

The unit goes to Airbag24 as a parcel, or you book UPS collection for an extra charge. After the repair, Airbag24 sends it back by UPS.

Packed securely against shocks, with the printed repair order in the parcel, the unit is well prepared.
