Airbag control unit with part number 4848802AE

What is the function of Airbag Control Unit 4848802AE?

The airbag control unit with part number 4848802AE is the central control module of the occupant safety system (SRS) in specific Dodge Viper models. It processes data from acceleration and crash sensors in real time to precisely and rapidly deploy airbags and seatbelt pretensioners in the event of a collision.

As an original equipment manufacturer (OEM) part, this component ensures secure communication between all sensors and passive safety devices. Part number 4848802AE is a current version that replaces earlier numbers such as 4848802AB and is also compatible with additional identifiers like 56038963AF, 4865582AB, 4865582AC, or P04865582AB. Its primary task is to detect a collision, assess its severity, and activate the appropriate restraint systems to provide optimal protection for occupants.

Why does control unit 4848802AE fail?

The most common cause of failure for control unit 4848802AE is the storage of crash data after an accident, which results in permanent deactivation of the system. Other defects arise from water damage, corrosion on the circuit board, or purely electronic malfunctions due to failure of internal components.

Stored crash data is the primary reason for malfunction. After a collision, the control unit locks itself for safety reasons, preventing further airbag deployment. This lock is permanent and can only be lifted through specialized electronic repair that resets the stored data.

Another frequent source of failure is environmental factors such as water damage. Intruding moisture causes corrosion on the sensitive traces and electronic components of the circuit board, potentially leading to short circuits and total system failure.

Electronic malfunctions are also widespread. Internal components like capacitors or the microcontroller may fail due to age or voltage spikes. These issues often manifest as internal error messages or complete loss of communication with the vehicle, even when no accident has occurred. Such a defect disables the entire airbag system and poses a significant safety risk.

How do you recognize a fault in 4848802AE?

A fault in the airbag control unit 4848802AE is primarily indicated by a permanently illuminated SRS or airbag warning light on the instrument cluster. Another clear sign is that the control unit is no longer accessible via the OBD interface and cannot communicate with diagnostic tools.

The most noticeable symptom is the continuously lit airbag warning light. It does not turn off after starting the vehicle, signaling that the restraint system is disabled and offers no protective function in the event of a crash.

In the workshop, the fault often shows up as a communication failure. The diagnostic tool cannot establish a connection with the airbag control unit to read out error codes or perform a system diagnosis. Stored error codes indicating an “internal control unit fault” further confirm hardware damage.

In which Dodge Viper models is 4848802AE installed?

The airbag control unit 4848802AE is specifically designed for various generations and variants of the Dodge Viper. This includes second-generation models (SR II), later series (VX I, VX II), and their performance-oriented ACR and GTS versions.

How does the repair of 4848802AE proceed at Airbag24?

Repair at Airbag24 involves precise electronic diagnostics to identify the fault, deletion of crash data, and replacement of defective components. The control unit is then thoroughly tested for full functionality and ready for reinstallation without additional coding. We offer 2 years' statutory liability for defects on every repair.

After submission to Airbag24, the control unit undergoes a standardized, proven repair process. First, comprehensive diagnostics are performed using specialized software to pinpoint the exact cause of the issue—whether it’s stored crash data, faulty microcontrollers, or defective capacitors.

In the next step, professional electronic refurbishment takes place. Stored crash data is completely and securely erased. Defective components on the circuit board are identified and replaced with new, high-quality parts. Finally, the device is reprogrammed to restore factory settings.

After repair, each control unit undergoes a rigorous final test to verify the flawless operation of all systems. Since the original unit is repaired, there’s no need for time-consuming re‑coding in the vehicle. The control unit is “plug-and-play” and can be directly reinstalled.
