Airbag control unit with part number 06772-SR2-305

What is the function of the airbag control unit 06772-SR2-305?

The airbag control unit with part number 06772-SR2-305 is the central control module of the occupant restraint system (SRS) in the Honda Del Sol EH. Its primary task is to process sensor data so that, in the event of a crash, the airbags and seatbelt pretensioners are deployed precisely and promptly to protect the occupants.

This specific SRS module is precisely tailored to the vehicle architecture of the Honda Del Sol from model years 1992 to 1998. It continuously monitors the connected crash sensors and the functionality of the airbag components. Upon impact, the control unit determines within milliseconds which restraint systems need to be activated.

After deployment, the unit stores so‑called crash data. This storage serves as a safety feature that prevents further use without professional inspection and repair, locking the system until it can be fixed.

What defects occur in 06772-SR2-305?

The most common cause of failure for the control unit 06772-SR2-305 is stored crash data following an accident. Other typical defects include internal electronic faults leading to communication issues, or physical damage caused by water ingress and short circuits.

A central and very common issue is the permanent storage of crash data after airbags or seatbelt pretensioners have been deployed. Such data cannot be cleared using standard workshop diagnostic tools, blocking the entire SRS system and making repair unavoidable.

Electronic faults on the circuit board are also a frequent source of problems. These often manifest as an inability to communicate with the control unit via the diagnostic interface. Error codes such as U1XXX or B1XXX indicate these communication interruptions or internal hardware failures.

In some cases, the diagnostic tool directly reports an internal fault or that error codes cannot be erased. This points to a serious defect in the module’s memory or processing unit. External factors like water damage can also lead to corrosion and short circuits, rendering the control unit unusable.

How do you recognize a defect in 06772-SR2-305?

The clearest symptom of a defect in the control unit 06772-SR2-305 is the permanently illuminated airbag warning light on the dashboard. Additionally, diagnostic equipment may fail to establish communication with the control unit, or stored error codes may remain unerasable.

The constantly lit airbag warning light is the primary alert for the driver, indicating that the occupant restraint system is either non‑functional or only partially operational, potentially failing to deploy in the event of a crash.

Another clear sign is when workshop diagnostic tools cannot establish communication with the airbag control unit. The unit becomes unreachable for external queries, suggesting a severe internal fault or a power supply problem.

Even if communication is possible but error codes such as “Internal Fault” or “Control Unit Defective” appear and cannot be reset, this indicates a defect within the control unit itself—especially after a crash when crash data has been stored.

In which models is 06772-SR2-305 installed?

The airbag control unit with part number 06772-SR2-305 was specifically developed for the Honda Del Sol. At Airbag24, we repair this control unit for the following specific vehicle model, as new parts are no longer available from the manufacturer.

Honda: Del Sol EH (also known as CRX del Sol), model years 1992–1998

How is 06772-SR2-305 professionally repaired?

Professional repair at Airbag24 includes precise diagnostics, targeted elimination of the root cause—such as resetting crash data or replacing defective components—and a final functional test. We provide 2 years' statutory liability for defects on every repair.

Once the removed control unit arrives at Airbag24, it first undergoes a thorough incoming inspection. Using specialized diagnostic software, stored error codes are read out and crash data analyzed to pinpoint the exact cause of the fault.

The core of the repair depends on the findings: stored crash data is completely and safely reset using dedicated software; if an electronic fault is detected, faulty components on the circuit board are replaced with high‑quality new parts.

Subsequently, the refurbished control unit undergoes rigorous quality control and functional testing to ensure full operability. Only after successful verification is the unit approved for return shipment.

Is it worth repairing 06772-SR2-305?

Yes, repair is the most economically and technically sensible solution. Since new parts for the Honda Del Sol are no longer available from the manufacturer, repair is the only way to restore your vehicle’s full safety at a fraction of the cost of rare used parts.

A key advantage is the significant cost savings. Repair is often 30–50% cheaper than purchasing a used replacement part, whose history and functionality remain uncertain. Repair ensures that your original control unit functions perfectly once again.

Restoration restores the airbag system to full working order, which is crucial for safety and for passing the mandatory technical inspection (TÜV). In addition, you receive 2 years' statutory liability for defects on the completed repair.
