2017-2020 Ferrari GTC4Lusso Airbag Module: V12 vs. V8 Fitment and Crash Data Secrets
This guide covers the critical differences between GTC4Lusso and GTC4Lusso T modules, recall information, and how to handle programming and crash data when replacing this vital safety component.
- The GTC4Lusso (V12) and GTC4Lusso T (V8) use different, incompatible airbag modules. You must match the OEM part number exactly.
- Modules from crashed cars contain 'crash data' and are locked. They must be replaced or sent to a specialist for a reset service, as a normal scanner cannot clear these codes.
- A replacement module (new or used) will require a 'Proxy Alignment' procedure at a Ferrari dealer or specialist to be recognized by the car.
- A major recall exists for the passenger airbag *inflator* on 2017-2018 models; this is separate from the control module but is a critical safety repair.
Vehicle-Specific Known Issues and Recalls
Major Safety Recall: Passenger Airbag Inflator
The 2017-2018 Ferrari GTC4Lusso and GTC4Lusso T are included in a major safety recall concerning the passenger-side frontal airbag. This is part of the widespread Takata airbag recalls that affected millions of vehicles from various manufacturers.
Recall Details:
- NHTSA Recall Number: 19V006000
- Ferrari Recall Number: 65
- The Defect: The airbag's inflator module may explode during deployment due to propellant degradation after long-term exposure to temperature fluctuations and humidity. An inflator explosion can result in sharp metal fragments striking vehicle occupants, potentially causing serious injury or death.
- The Remedy: Ferrari dealers will replace the passenger frontal airbag assembly free of charge.
Important: This recall involves the airbag inflator itself, not the electronic control module. However, it is a critical safety issue for all owners. You can check if your specific vehicle is affected by entering your VIN on the NHTSA website.
Potential Module Fault (Australia Recall)
An Australian recall for 2017-2018 GTC4Lusso and GTC4Lusso T models noted a potential power supply failure within the TRW-made airbag ECU (control module). This could cause the airbags and seatbelt pre-tensioners to malfunction. While this was a regional recall, it points to a potential, albeit rare, manufacturing issue with the module itself.
Critical Fitment Warning: GTC4Lusso (V12) vs. GTC4Lusso T (V8)
The most significant challenge when replacing this part is ensuring you have the correct module for your specific GTC4Lusso model. The V12 and V8 versions use different airbag control modules.
Warning: The airbag control module for the GTC4Lusso (with the V12 engine) is NOT compatible with the GTC4Lusso T (with the V8 engine). The modules are programmed differently to account for the unique characteristics and safety systems of each powertrain. Installing the wrong module will result in a system malfunction and an illuminated airbag light.
Before purchasing a replacement, you must visually inspect your original module and exactly match the OEM part number. The two known OEM part numbers are 315396 and 340216. Do not order a part based on your vehicle's model name alone; physical verification is mandatory.
Symptoms of a Failing Airbag Module
A faulty airbag module will almost always make its presence known immediately.
- Airbag Warning Light: The most common symptom is an illuminated airbag warning light on your instrument cluster. This indicates the SRS system has detected a fault and has been disabled. The system will not function in an accident while this light is on.
- Failure to Communicate: A professional scan tool may be unable to establish communication with the airbag module, pointing to a complete internal failure.
- Fault Codes Stored: A scan will reveal specific Diagnostic Trouble Codes (DTCs). Common codes for module failure include internal errors, communication loss, or crash data storage.
- U0151: Lost Communication With Restraints Control Module
- B1015 / B1620: Internal Control Unit Error
- B1193: Crash Data Stored / Memory Full
Buying a Used Air Bag Control Module
Due to the high cost of a new OEM module from Ferrari, a used part is a practical option. However, you must be an informed buyer to avoid common pitfalls.
Step 1: Understand "Crash Data"
When a vehicle is in an accident that causes the airbags or seat belt pre-tensioners to deploy, the airbag module records this event as "crash data" or "hard codes". This data permanently locks the module, rendering it inoperable. This is a safety feature to ensure the vehicle is properly inspected after a crash.
- This crash data cannot be cleared with a standard OBD-II scanner or even most professional shop scanners.
- A module with crash data will cause the airbag light to stay on, and the safety system will not work.
Step 2: Choose Your Purchasing Strategy
You have two main options when buying used:
- Buy a Guaranteed "Clean" Module: Purchase a module from a reputable auto recycler that guarantees the part was sourced from a non-wrecked vehicle and is free of crash data. This is the most straightforward option but may cost more.
- Buy Any Used Module and Have It Reset: You can purchase a module from any source (even one from a crashed car) and mail it to a specialized service that resets airbag modules. These services use specific tools to connect directly to the module's internal chip and wipe the crash data, returning it to factory condition. This is often the most cost-effective path.
Pro Tip: If possible, the best option is to have your vehicle's original module reset. This avoids any potential programming or VIN mismatch issues, as the module is already coded to your car. You only need a replacement module if the original is physically damaged by water, fire, or impact.
Step 3: Physical Inspection
When you receive the used module, inspect it carefully for:
- Corrosion: Check the pins on the electrical connectors for any green or white crust, which indicates water damage.
- Physical Damage: Look for cracks in the casing or bent mounting tabs.
- Burn Marks: Any sign of scorching or melting points to a severe internal electrical failure.
Installation and Programming Requirements
Module Location
The airbag control module is typically located in the center of the vehicle for maximum protection and accurate sensor readings. In the Ferrari GTC4Lusso, it is found under the center console, bolted to the vehicle's transmission tunnel. Access requires careful removal of interior trim panels.
Programming and Calibration
A replacement airbag module, whether new or a cleared used unit from another vehicle, will likely need to be programmed to your car's specific configuration. In the Ferrari world, this procedure is often called a "Proxy Alignment."
- A proxy alignment is a process that allows all the vehicle's computers (ECUs) to recognize the new module and synchronize with it.
- This procedure requires a dealer-level diagnostic tool, such as the Ferrari DEIS or a compatible high-end scanner. Most independent shops and DIY mechanics will not have this capability.
- Failure to perform a proxy alignment will result in a flashing odometer and a persistent airbag warning light.
A visit to a Ferrari dealership or a specialist independent shop with the proper equipment is almost always required after installing a replacement module.

Frequently Asked Questions (FAQ)
Does a used GTC4Lusso airbag module need to be programmed?
Yes, almost certainly. If you install a module from another car (even a used one that has been reset), it will need to be synchronized with your vehicle's other computers via a "proxy alignment" procedure. This requires a dealer-level scan tool. The only way to potentially avoid this is by having your car's original module reset and reinstalling it.
What is "crash data" and can I clear it myself?
Crash data is a permanent record of a collision stored in the airbag module. It locks the module for safety reasons. You cannot clear this data with a standard OBD-II scanner. It requires specialized equipment to directly access the module's memory chip. You must send the module to a professional reset service.
Where is the airbag module located on the 2017-2020 GTC4Lusso?
The airbag control module is located under the center console, bolted to the floor/transmission tunnel. This central location helps it accurately detect impact forces and protects it from damage.
Is it safe to drive with the airbag light on?
No. While the car will still drive, an illuminated airbag light means the entire Supplemental Restraint System (SRS) is disabled. In the event of an accident, the airbags and seat belt pre-tensioners will not deploy, significantly increasing the risk of serious injury. The issue should be diagnosed and repaired immediately.
