Airbag control unit with part number 98 237 414 80

What is the function of Airbag Control Unit 98 237 414 80?

The Airbag Control Unit 98 237 414 80 is an original OEM component from Continental, serving as the central controller for the Supplemental Restraint System (SRS). It processes signals from crash sensors, deploys airbags and seatbelt pretensioners in the event of a collision, thereby protecting occupants.

As the “brain” of the passive safety system, this component continuously monitors all connected sensors and actuators. The control unit, featuring SPC560P50 memory type, evaluates data from acceleration and pressure sensors in real time. In the event of a crash, it makes the critical decision on which restraint devices should be deployed and at what intensity.

At the same time, the unit logs the system status and stores fault codes essential for workshop diagnostics. Proper functionality is crucial to ensure occupant protection at all times.

Why does Control Unit 98 237 414 80 fail?

The most common cause of failure for Control Unit 98 237 414 80 is the storage of crash data after an accident, which effectively locks the unit hardware‑wise. Other causes include internal electronic malfunctions, water damage, power supply defects, or issues with wiring to the SRS system.

Following a traffic accident in which airbags or seatbelt pretensioners have been deployed, the control unit permanently stores so‑called crash data. This lockout is a manufacturer‑imposed safety measure designed to force a full system check. Without professional repair that clears these stored data, the control unit remains non‑functional and displays a persistent error code.

Additionally, environmental factors such as moisture ingress can lead to corrosion and short circuits on the circuit board. Internal electronic faults—such as those related to the power supply (notably PSA error code 34)—or complete communication failure with diagnostic tools are also typical defects indicating hardware damage inside the unit.

External factors like broken wires, incorrect wiring, or loose connectors can likewise impair SRS functionality, sometimes falsely suggesting a control unit defect. A thorough professional diagnosis is therefore essential. Note that the frequently interchangeable part number 98 237 413 80 may present similar symptoms.

How do you recognize a defect in 98 237 414 80?

A defective Airbag Control Unit 98 237 414 80 primarily manifests as a constantly illuminated SRS warning light on the instrument cluster. Often, communication with the control unit via an OBD diagnostic tool becomes impossible, complicating fault analysis.

The most obvious symptom is the red‑lit airbag warning light, which fails to extinguish after starting the vehicle, signaling a serious fault in the restraint system that endangers occupant safety.

Another clear indication occurs when the workshop’s diagnostic equipment can no longer access the control unit. The message “No Communication” often points to a total internal electronics failure, preventing the retrieval of fault codes needed to further narrow down the issue.

In some cases, specific fault codes can be read out, directly indicating an internal defect within the control unit. For example, PSA error code 34 suggests a problem with the unit’s internal power supply.

In which vehicles is Control Unit 98 237 414 80 installed?

Control Unit 98 237 414 80 is primarily used in vehicles manufactured by the PSA Group. It is commonly found in models such as the Peugeot 2008 II and the Peugeot Rifter I. Compatible Citroën models like the Berlingo or Jumper may also utilize this unit.

At Airbag24, we repair Control Units with part number 98 237 414 80 for the following vehicle models:

Peugeot: 2008 II (model years 2020–2023, including facelift versions from 2023 onward), Rifter I (model years 2018–2024, including facelift versions from 2024 onward)

Due to the manufacturer’s platform strategy, this part number may also appear in other Citroën models such as the Berlingo or Jumper. Verifying the part number on the removed unit is always required for successful repair.

How is Control Unit 98 237 414 80 professionally repaired?

Professional repair of Control Unit 98 237 414 80 involves detailed fault analysis, elimination of internal defects, and clearing of stored crash data. After component‑level restoration and a final system test, the unit is fully operational again without requiring reprogramming.

After you send the removed control unit to Airbag24, the repair process begins with a thorough diagnosis. Our technicians read out the fault memory and inspect the hardware for visible and electronic damage.

The core of the repair lies in eliminating the root cause of the fault. For stored crash data, a special “crash-data-clearing” procedure is applied. In cases of electronic defects, the faulty components on the circuit board are identified and replaced with new, high-quality parts.

Subsequently, the refurbished control unit undergoes an extensive final test on the simulator to ensure proper functionality across all system areas. Since the original vehicle configuration is preserved, the unit operates like a brand-new component after reinstallation and requires no additional coding or programming. We provide 2 years' statutory liability for defects on all repairs.
