Airbag control unit with part number 68480707AC

What is the function of the airbag control unit 68480707AC?

The airbag control unit with part number 68480707AC is the central control module for the passive safety system in the third-generation Chrysler Voyager (1995–2000). It processes signals from crash sensors and determines whether to deploy airbags and seatbelt pretensioners, providing optimal protection for occupants during a collision.

As the “brain” of the restraint system, this module continuously monitors all connected components—from impact sensors at the front of the vehicle to individual airbag modules and seatbelt pretensioners.

In the event of a collision, it analyzes incoming data within milliseconds. When predefined thresholds are exceeded, it sends ignition pulses to the appropriate pyrotechnic charges, activating the protective systems promptly.

Why does the control unit 68480707AC fail?

A failure of the 68480707AC control unit is usually caused by crash data being stored after an accident, which prevents further functionality. Other causes include internal electronic faults, water damage, or voltage surges that can lead to complete module failure.

The most common reason for replacement or repair is airbag deployment. After a crash, the control unit permanently writes crash data into its internal memory—a manufacturer‑imposed safety measure designed to prevent reuse without professional inspection and restoration.

In addition, purely electronic malfunctions may occur. Defective components on the circuit board, cold solder joints, or memory errors can result in internal malfunctions detected by the system itself and indicated by the illuminated airbag warning light.

External factors such as moisture ingress through a leaking body panel or voltage spikes in the vehicle’s electrical system—such as during jump-starts—can also cause permanent damage to the sensitive electronics.

Technically identical or similar functions are also found in control units with related part numbers 4686602AI, 03620433B, and 68000020AI, which were likewise installed in the third generation of the Chrysler Voyager.

How do you recognize a defect in the 68480707AC?

A defective 68480707AC control unit typically manifests as a constantly lit or flashing airbag warning light on the instrument cluster. Often, communication with a diagnostic tool becomes impossible, or specific fault codes such as 65535 or B1000 appear, indicating an internal malfunction.

The clearest sign is the airbag warning light that fails to turn off after the engine starts. This indicates a fault in the restraint system, compromising occupant safety since proper airbag deployment cannot be guaranteed in the event of a crash.

Another clear symptom occurs when the workshop’s diagnostic equipment can no longer access the airbag control unit. The module does not respond to queries, making precise fault diagnosis on the vehicle impossible.

The fault memory often contains non‑erasable error codes. Codes like 65535, B1000, or 93F9 directly point to an irreparable internal fault in the control unit. Messages such as “Driver/Passenger airbag resistance too high” may also stem from a faulty control unit, even if the airbags themselves remain intact.

In which vehicles is the 68480707AC control unit installed?

The part number 68480707AC is specific to models of the third-generation Chrysler Voyager produced between 1995 and 2000. This includes the standard version as well as the Voyager S and Voyager AS variants. Other vehicle generations use different part numbers.

At Airbag24, we repair the airbag control unit with part number 68480707AC for the following Chrysler Group models:

Chrysler Voyager, third generation (model years 1995–2000, GH/GS platform)

Chrysler Voyager S

Chrysler Voyager AS

It is important to note that earlier or later generations of the Chrysler Voyager utilize different control units with their own part numbers. Repairs must always correspond to the exact part number to ensure full compatibility and safety.

Is repairing the 68480707AC worthwhile?

Yes, repairing the 68480707AC is an economically and technically sensible alternative to costly new purchases. It offers savings of up to 90% compared to a new unit, restores full functionality, and comes with 2 years’ statutory liability for defects.

The biggest advantage is the substantial cost reduction. A new factory‑original control unit can cost up to €750, whereas a repair represents only a fraction of that expense. The refurbished, tested unit then performs just like a brand‑new component.

Professional refurbishment restores the original factory specifications. Stored crash data is completely erased, and any hardware defects are repaired, ensuring the safety system functions flawlessly once again.

Unlike used control units, whose origin and condition are often unclear and which may pose challenges due to vehicle-specific coding, the refurbished original part is immediately ready for use in your own vehicle.

2 years’ statutory liability for defects is provided on every repair performed, offering added assurance and confidence in the quality of our work.

How does the repair process at Airbag24 work?

The repair process at Airbag24 is simple and transparent: you send us the removed control unit 68480707AC, our technicians conduct a detailed diagnosis, restore it to factory settings, repair any hardware issues, and return it to you after a successful functional test.

In the first step, the defective airbag control unit is removed from the vehicle by you or your workshop. It is recommended to read out the fault memory before removal to document the symptoms.

Upon submission to Airbag24, the device undergoes a professional analysis. Our technicians check whether crash data is stored or if there is an electronic defect on the circuit board.

The actual repair involves securely erasing crash data or restoring the hardware through expert soldering and replacing faulty components. The goal is to reinstate the original factory condition.

Finally, each repaired control unit undergoes a comprehensive functional test to ensure proper operation. We provide 2 years' statutory liability for defects on all our repairs.
