Airbag control unit with part number 95AG14B056CG

What is the function of the airbag control unit 95AG14B056CG?

The airbag control unit with part number 95AG14B056CG is an original Ford OEM safety module (SRS), primarily installed in the Ford Escort. Its main task is to monitor the entire occupant protection system. It processes signals from collision sensors and, in the event of a crash, controls the deployment of airbags as well as the storage of relevant crash data.

As the central control unit of the passive safety system, this module—also known as the SRS module—is responsible for analyzing data sent by the vehicle’s acceleration sensors. It determines within milliseconds whether an impact exceeds the predefined thresholds for airbag deployment.

An additional key function is the continuous recording of crash data after deployment or a significant accident. For safety reasons, this data locks the control unit, requiring professional repair to reset it so the system can function again.

What defects occur in the 95AG14B056CG?

The most common cause of failure for the 95AG14B056CG control unit is the accumulation of crash data that locks the module after an accident. Other defects arise from aging electronic components, moisture ingress, or internal faults in the deployment circuitry. Repairs focus on erasing crash data and restoring the internal electronics.

Stored crash data is the primary reason these control units are sent in for repair. After a crash, the module intentionally locks itself to prevent reuse without professional diagnostics. This condition is often logged as an internal fault in the error memory.

Due to the vehicle’s age, hardware failures caused by aging are also common. Internal components on the circuit board, such as the deployment circuits, may fail, potentially triggering specific error codes like B0028, which indicates a problem in the front airbag circuit.

Moisture that penetrates the vehicle interior over time can also lead to corrosion on the circuit board and subsequent malfunctions. Before removal, it’s crucial to verify that the issue does not stem from external wiring or sensors. Similar part numbers, such as 95AG14B056CE, exist, underscoring the need to confirm the exact part number when repairing or replacing the unit.

How do you recognize a defect in the 95AG14B056CG?

A defective 95AG14B056CG control unit typically manifests as a permanently illuminated airbag warning light on the instrument panel. Often, communication between the control unit and a diagnostic tool via the OBD-II interface is also lost. Stored error codes like B0028 further indicate an internal problem.

The clearest symptom is the persistently lit airbag warning light. It fails to extinguish after starting the vehicle, signaling that the entire restraint system is disabled and would not deploy in the event of a crash.

Another frequent sign is complete loss of communication with the diagnostic tool. The workshop cannot read any error codes because the control unit no longer responds to requests through the OBD-II port—clear evidence of a serious internal malfunction.

If communication remains possible, specific error codes are stored in the memory. For example, error code B0028 directly points to a problem in the front airbag deployment circuit, often originating within the control unit itself.

In which models is the 95AG14B056CG installed?

The airbag control unit 95AG14B056CG is specifically used in various Ford Escort models, including the Ford Escort Mk4 and the Ford Escort 7, also known as the Escort ’95, produced between 1995 and 2000. At Airbag24, we repair this control unit for all compatible vehicle variants.

At Airbag24, the control unit with part number 95AG14B056CG is professionally refurbished for the following Ford models:

Ford Escort Mk4

Ford Escort 7 ’95 (model years 1995–2000)

Compatibility extends to variants such as the Escort ’95, Express/CE14, and body styles like GAL and Berlina Turnier. The primary model-year range for using this control unit spans from 1990 to 1998. Verifying the printed part number on the original component is essential to ensure compatibility.

How does the repair of the 95AG14B056CG proceed at Airbag24?

Upon receipt of the 95AG14B056CG control unit at Airbag24, our technicians conduct a thorough analysis to identify the precise cause of the fault. The repair includes professionally erasing stored crash data and fixing any defective electronic components. Final functional tests confirm full operability, backed by 2 years' statutory liability for defects.

Ideally, your workshop should generate a fault log before removal and include it with the package. Upon submission to Airbag24, the unit will first undergo an incoming inspection, during which, if possible, the fault memory will be read out.

The central step of the repair is the safe and complete reset of the crash data. This process restores the control unit to operational readiness. If additional hardware defects are present in electronic components such as the trigger circuits, these will be professionally repaired.

Subsequently, each repaired control unit undergoes a final functional test on a specialized test bench. This simulates vehicle operation and ensures that all functions have been fully restored. Of course, every repair comes with 2 years' statutory liability for defects.
