Airbag control unit with part number 68425814AF

What does the airbag control unit 68425814AF do?

The airbag control unit 68425814AF evaluates the signals of the crash sensors within the restraint system (SRS) of Jeep. In an accident, it triggers the appropriate airbags and seatbelt pretensioners within milliseconds. After an accident, it stores crash data and locks itself.

During operation, the unit checks the system for faults continuously. It records any deviations it finds in the fault memory and displays them.

The display in the instrument cluster is therefore the most important feedback from the system to the driver.

Why does the control unit 68425814AF fail?

The most common cause is crash data from an accident, even if no airbag has deployed; normal diagnostic tools cannot erase it. Other causes include aged components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Airbag24 erases the crash data as a fixed part of the repair.

Components age over time, and solder joints can go cold. Moisture and corrosion attack the contacts, and voltage spikes come, for example, from a weak battery or a jump-start.

How can you tell that the 68425814AF is defective?

A fault makes itself known through error messages in the instrument cluster and an airbag warning light that stays on permanently or intermittently. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

• Airbag warning light staying on permanently
• Airbag warning light coming on intermittently
• Error message in the instrument cluster
• No connection to the diagnostic tool
• Fault memory cannot be cleared

If any of these signs occurs, have the fault memory read out before taking any further steps.

You make the label check using the part number on the removed control unit; it only shows that it is the right unit. Have the fault memory read out beforehand, because this result reveals whether the control unit is defective or whether a plug or cable is the cause.

How does the repair of the 68425814AF work?

First, read out the fault memory and enclose the log, then disconnect the battery. Only after that remove the control unit, create a repair order online and send in the well-packed unit.

Airbag24 checks the unit on the test bench, replaces defective components, erases the crash data and carries out a function test. The unit then goes back to you.

Processing at Airbag24 usually takes 3–4 working days, and this time covers testing, repair and function testing only. 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 68425814AF get to Airbag24?

You send the unit to Airbag24 as a parcel or book a UPS collection for an extra charge. The return after the repair is made by UPS.
