Airbag control unit with part number 68346726AB

What does the airbag control unit 68346726AB do?

The airbag control unit 68346726AB coordinates the SRS restraint system of Dodge. It monitors the crash sensors, decides within milliseconds in the event of an impact whether airbags and seatbelt pretensioners are triggered, and checks the system continuously.

The sensors and the triggering elements are connected to the control unit. If it reports a fault, it creates a fault entry and displays it via the airbag warning light.

After an accident, the control unit stores crash data and then locks itself. This storage is part of the design of the system.

Why does the control unit 68346726AB fail?

Stored crash data are the most common cause, even if no airbag was deployed; a normal diagnostic tool cannot erase them. Added to this are aged electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes, for example from a weak battery or jump-starting.

The data are held in the control unit, regardless of whether the airbags deployed.

Electronic components are subject to ageing, and moisture or corrosion on plug connections can impair the contacts. Cold solder joints lead to intermittent connections.

Voltage spikes stress the electronics, whether they come from a weak battery or from a jump-start.

How can you tell that the 68346726AB is defective?

A defect is recognisable by the airbag warning light in the instrument cluster lighting up constantly or intermittently, accompanied by an error message in the instrument cluster. It also indicates a defect if the diagnostic tool cannot find a connection to the control unit or the fault memory cannot be cleared; then airbags and seatbelt pretensioners may not deploy in an emergency.

The light only reports that something in the system is wrong. Which cause lies behind it remains open at first and is narrowed down only by the read-out.

A fault memory that cannot be cleared is a further signal. It is not a coincidence but feedback from the system.

Before you send the unit in, these points are important. Comparing the part number on the label of the removed unit with this page ensures that it is the correct unit. Whether the control unit is defective or a connector or cable is the cause is shown only by the read-out fault memory, which is why you should have it read out in advance.

For the same vehicles, we also repair control units with the part numbers 0285015046, 56043128AC, 56043128AD, 68303217AA, 68303218AA, 68346712AA.

How does the repair of the 68346726AB work?

First have the fault memory read out and attach the log. Then disconnect the battery and only then remove the control unit; afterwards create a repair order online and send the carefully packed unit in. Airbag24 checks the unit on the test bench, replaces defective components, erases stored crash data and carries out a function test, after which the unit goes back to you.

The order is mandatory so that the removal takes place safely. Work on the control unit may only begin after the battery has been disconnected.

Processing at Airbag24 takes 3–4 working days and covers only checking, repairing and testing. Shipping and the steps before it are not included.

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.
