Airbag control unit with part number 5WY67123-95160

What is the function of the airbag control unit 5WY67123-95160?

The part number 5WY67123-95160 refers to an OEM airbag control unit (SRS ECU), primarily installed in models such as the Daewoo Gentra T250. It continuously monitors crash sensors, determines whether to deploy airbags and seatbelt pretensioners, and stores all relevant fault and crash data in non-volatile memory.

As the central control unit of the passive safety system (SRS – Supplemental Restraint System), this module interprets signals from acceleration and pressure sensors throughout the vehicle. In the event of a crash, it decides within milliseconds which restraint systems—such as front or side airbags and seatbelt pretensioners—should be activated to provide optimal occupant protection.

All system faults, such as a defective sensor or faulty connection, are logged in the fault memory and trigger activation of the SRS warning light. Following deployment, irreversible crash data is also stored, preventing further use of the control unit without proper repair.

An alternative, verified OEM part number for this unit is 94 833 085. Compatibility is guaranteed only when the numbers match exactly.

Why does the control unit 5WY67123-95160 fail?

The most common causes of failure for the control unit 5WY67123-95160 are the storage of crash data after airbag deployment and internal hardware defects on the circuit board, resulting in error codes such as “Internal Error.” Other causes include damage from moisture, overvoltage, or issues with external wiring.

After a crash involving airbag deployment, the control unit stores so‑called crash data—a safety measure that locks the module and prevents reuse without professional inspection and repair. The device itself may not be technically defective but remains disabled for operation.

More frequently, however, failures stem purely from electronic issues on the circuit board. Defective SMD components—such as MOSFETs, resistors, capacitors, or voltage regulators—can fail. Cracked solder joints or corroded traces can also lead to total failure or communication problems.

External factors like penetrating moisture, surge damage from jump-starts, or mechanical damage to the housing or connectors can likewise destroy the complex electronics of the control unit.

How do you recognize a defect in the control unit 5WY67123-95160?

A defective airbag control unit 5WY67123-95160 typically manifests as a permanently illuminated SRS warning light on the instrument cluster. Often, the control unit can no longer be read by diagnostic equipment, or specific error codes such as “Internal Control Unit Error” are stored and cannot be cleared.

The most obvious sign is the active airbag warning light (SRS lamp). It fails to turn off after starting the vehicle, indicating a fault in the system’s self‑test and signaling that airbags might not deploy in the event of a crash.

Another clear symptom is complete loss of communication. The workshop cannot connect to the airbag control unit using diagnostic tools to read or clear errors; the module becomes unreachable to the vehicle’s onboard network.

If diagnostic logs display error codes like “Internal Error” or memory errors, this directly points to an irreparable hardware defect inside the control unit. Such errors cannot be resolved simply by clearing them and require electronic repair.

In which vehicles is the control unit 5WY67123-95160 installed?

The airbag control unit with part number 5WY67123-95160 and its alternative number 94 833 085 is specifically designed for certain vehicle models. At Airbag24, we primarily repair this control unit for the Daewoo Gentra T250 series, produced between approximately 2006 and 2017.

At Airbag24, we service the control unit with part number 5WY67123-95160 for the following model:

Daewoo: Gentra T250 (circa model years 2006–2017)

For successful repair, exact matching of the part number is essential. Even minor discrepancies can indicate different software versions or pin configurations, leading to incompatibility with the vehicle.

How is the repair of the control unit 5WY67123-95160 carried out?

After being sent to Airbag24, the control unit 5WY67123-95160 undergoes a professional diagnosis, during which fault and crash data are retrieved. This is followed by electronic repair at the component level, including handling of crash data. Final functional tests confirm full operability, backed by 2 years' statutory liability for defects.

The repair process at Airbag24 follows a proven, technical procedure. Upon receipt of the package, the control unit undergoes a visual inspection and its part number is verified. Next, the fault memory is read out to document the exact cause of the error.

In the next step, electronic refurbishment is performed on the circuit board. Our technicians locate and replace defective components such as voltage regulators or memory chips using professional rework equipment. Stored crash data that prevents proper functionality is carefully reset during the repair process.

Following the repair, the control unit is thoroughly tested on a specialized test bench. This simulates flawless communication and operation across all relevant functions. Only after a successful final test is the unit approved for return shipment.

You naturally receive 2 years' statutory liability for defects on the completed repair.
