Airbag control unit with part number 1495658080

What is the function of Airbag Control Unit 1495658080?

The airbag control unit with part number 1495658080 is the central control module of the occupant safety system (SRS), primarily installed in models such as the Peugeot 806 and Citroën C8. It is often manufactured by Autoliv and is responsible for processing sensor data and activating the airbags and seatbelt pretensioners in the event of a crash.

As the “brain” of the safety system, this module continuously processes information from various crash sensors distributed throughout the vehicle. When it detects a collision strong enough to warrant activation, it sends critical ignition signals to the appropriate airbags and pyrotechnic seatbelt pretensioners within milliseconds.

A notable feature of this control unit is its compatibility with several related part numbers, including 1400596980, 6547.R6, 1480999080, PSA 8200656329, and Temic L4V2M13AE72. This highlights its widespread use across PSA, Fiat, and Lancia vehicle platforms of that era.

Why does control unit 1495658080 fail?

Failures of control unit 1495658080 are often due to internal electronic defects that can occur even without an accident. The main causes include component aging, damage caused by moisture ingress, or secondary damage resulting from improper repair attempts. These defects typically lead to complete communication failure or persistent internal malfunctions.

A common symptom is the failure of electronic components on the circuit board, which may involve processors, memory chips, or other peripheral parts essential for proper operation. Such defects usually develop gradually and ultimately disable the entire airbag system.

Moisture is another critical factor. Water ingress—whether through body panel leaks or condensation—can cause corrosion on the circuit board and short circuits, potentially damaging the control unit.

It is also not uncommon for units to be returned after unsuccessful repair attempts. Incorrect soldering techniques or the replacement of unsuitable components can exacerbate the original fault and complicate subsequent professional repairs.

How do you recognize a defect in control unit 1495658080?

A defective control unit 1495658080 typically manifests as a permanently illuminated airbag warning light on the dashboard that cannot be turned off. Communication with diagnostic equipment is often impossible, and error messages such as “Airbag malfunction” or “Refer to manual” appear on the display.

The most obvious sign is the persistently lit airbag warning light, indicating that the entire restraint system is inoperative and will not deploy in the event of a crash. Such a vehicle would fail the mandatory technical inspection (TÜV/VU).

Another clear symptom is the loss of communication with the control unit. Workshops can no longer access the module using diagnostic tools to read or clear fault codes, as the device simply stops responding to requests.

In addition, specific error messages may appear on the instrument cluster or onboard computer, including general warnings like “Airbag malfunction,” more detailed alerts such as “Crash sensor/seat airbag malfunction,” or messages related to the “fuel shut-off valve,” all pointing to an internal issue within the SRS module.

In which vehicles is control unit 1495658080 installed?

Control unit 1495658080 is mainly used in the first generation of the Peugeot 806 and Citroën C8. Due to collaborations at the time, it is also compatible with and found in similar models such as the Fiat Ulysse, Lancia Zeta, and Peugeot 807.

At Airbag24, we repair part number 1495658080 for the following specific models and series:

Peugeot: 806 I (model years 1994–1998) and the facelifted version (1998–2002), as well as the compatible Peugeot 807.

Citroën: C8 I (model years 2002–2008) and the facelifted model (2008–2014).

Fiat & Lancia: The control unit is also installed in the Fiat Ulysse and Lancia Zeta, which share the same technical platform.

How does the repair process work at Airbag24?

The repair process at Airbag24 begins with the secure shipping of your removed control unit to us. Our technicians perform a thorough diagnosis and resolve the electronic fault at the component level. Following successful repair and a final functional test, we return the unit to you with 2 years' statutory liability for defects.

After removing the unit—often located behind the glove compartment or under the driver’s seat—please pack it securely for transport and send it to us along with the completed repair form.

In our workshop, the control unit undergoes a thorough inspection to pinpoint the exact cause of the fault. Repairs are carried out directly on the circuit board, which may involve re-soldering connections, replacing defective microchips, or addressing moisture damage.

Following repair, the control unit is tested on a specialized test bench to ensure it functions like new and all features operate flawlessly. Only after this quality check is the unit shipped back to you. Of course, you receive 2 years' statutory liability for defects on the completed repair.

Is repairing control unit 1495658080 worthwhile?

Yes, repair is the most economical and sensible solution. A new unit often costs over 500 euros and is rarely available for these older vehicle models. Professional refurbishment is significantly cheaper, restores full functionality, and comes with 2 years' statutory liability for defects.

The key advantage is the substantial cost savings compared to purchasing a new unit. You typically save more than half the price of a new control unit, without compromising safety or performance.

Since this is the original unit from your vehicle, its original configuration remains intact. This avoids compatibility issues that can arise when using used parts from scrapyards, which are often sold without any warranty.

Repair is also a sustainable choice. By refurbishing existing electronics, we conserve valuable resources and help reduce electronic waste.
