Airbag control unit with part number 7088878

What is the function of Airbag Control Unit 7088878?

The airbag control unit with part number 7088878 is the central control module for the occupant protection system (SRS) in the Daewoo Kalos T200. It continuously analyzes data from the acceleration sensors to precisely deploy the airbags and seatbelt pretensioners in the event of a crash. It is also known by the alternative part number 27120503.

This control unit, often referred to as the SRS module (Supplemental Restraint System), serves as the brain of the passive safety system. It monitors all connected components, including crash sensors, seat occupancy detectors, seatbelt pretensioners, and the airbag modules themselves.

Its primary task is to interpret signals received from the sensors. When values indicate a collision, it sends ignition pulses to the appropriate restraint systems. Following such an event, the unit permanently stores the crash data, often necessitating repair or a reset.

Why does Control Unit 7088878 fail?

The most common cause of failure for Control Unit 7088878 is the storage of crash data after an accident. This data locks the unit’s functionality and cannot be cleared using standard diagnostic tools. Other causes include internal electronic malfunctions, water damage, or issues with the power supply.

After a collision—even minor ones—the control unit is locked for safety reasons. This lock ensures that the system is inspected by a qualified workshop following a potentially damaging event. Resetting this crash data requires specialized equipment and technical expertise.

In addition to crash-related failures, electronic malfunctions can occur. These include defects in internal circuit board components or errors caused by external factors such as moisture. Fluctuating vehicle voltage—often due to a faulty battery—can also lead to sporadic malfunctions or complete system failure.

How do you recognize a fault in 7088878?

A defect in Airbag Control Unit 7088878 primarily manifests as a constantly illuminated or flashing SRS warning light on the instrument panel. Often, communication between the control unit and a diagnostic tool is no longer possible. In this state, the entire airbag system is disabled and offers no protection.

The activated airbag warning light is the clearest indicator. It signifies that the system has detected a critical error and is no longer operational. Ignoring this warning poses a significant safety risk.

In the workshop, the fault is often evident when access to the SRS module’s fault memory is denied. Stored error codes—especially those indicating “internal error” or “crash data stored”—cannot be erased using standard diagnostic tools.

In which vehicles is 7088878 installed?

Part number 7088878 is the original airbag control unit for the Daewoo Kalos T200 model, manufactured between 2002 and 2011. This model was also marketed under the Chevrolet brand. Airbag24 offers specialized repairs for this specific control unit and its variants.

How is Control Unit 7088878 professionally repaired?

Professional repair at Airbag24 includes a detailed analysis, targeted clearing of stored crash data, and restoration of defective electronic components. After a successful functional test, the control unit is fully operational again. We provide 2 years' statutory liability for defects on all repairs.

Following proper removal—which, according to regulations, should be performed by a certified workshop—the control unit is sent to Airbag24. Our technicians first conduct a comprehensive diagnosis to pinpoint the exact source of the fault.

The core of the repair involves erasing crash data at the hardware level using specialized programming tools. If physical damage to components is identified during analysis, these parts are expertly replaced.

Finally, each repaired control unit undergoes a simulation test. After reinstallation and return to the vehicle, only the fault memory needs to be cleared to deactivate the warning light.

Is repairing 7088878 worthwhile?

Yes, repairing Control Unit 7088878 is both economically and technically sensible. You save significantly compared to purchasing a new unit, which can cost up to €750. Moreover, the repaired unit is immediately ready for installation, without requiring time-consuming reprogramming of the vehicle.

A new control unit from the manufacturer is not only expensive but often requires vehicle-specific coding, which incurs additional workshop costs. Repairing your original unit bypasses this issue, as the vehicle’s original configuration remains intact.

With over 20 years of experience, Airbag24 offers a proven and reliable solution. You’ll receive your own refurbished control unit back and can count on restored safety, backed by 2 years’ statutory liability for defects.
