How to Read and Clear Lamborghini Fault Codes
Owning and driving a Lamborghini sure is fun, but the sight of the illuminated check engine light can send shivers down the spine of even the most seasoned Lamborghini owner. There are plenty of warning lights, such as ABS, SRS, transmission temperature, oil pressure, battery charging, differential, and tract control. But fear not; this guide will equip you with the knowledge and tools to read and erase these cryptic codes and restore your beloved vehicle to its top.
Procedure
All Lamborghini since 1996 have OBD-II. Huracán, Aventador, Diablo, Gallardo, Urus, Centenario, and others are common models. Here are the steps on how to read DTCs or Fault codes:
- Gather the necessary tools: Equip yourself with a Professional-Grade OBD-II Scanner compatible with your Lamborghini. Click Here for our Professional-Grade YOUCANIC Scanner
- Access the OBD-II Port: This port is usually found near the steering column under the dashboard. The OBD-II port is the gateway to your car’s diagnostic information. Turn the ignition key to the “ON” position without starting the engine to make a connection with the vehicle’s computer. If your Lamborghini has a START/STOP feature, press the button without pressing the brake pedal. Do not start the engine. If you are unsure of the OBD-II port of your vehicle, you can always check the Car Owner’s Manual.
- Access the Diagnostic Menu: On the YOUCANIC scanner’s display, navigate to the “Diagnostic” or “Scan” menu. This menu allows you to access various diagnostic functions for your Lamborghini.
- Select ‘Lamborghini’ as the Vehicle Make: This ensures the scanner effectively communicates with the Lamborghini On-Board Diagnostic system and effectively scans the fault codes.
- Select option for model selection: The scanner has various options for model selection. You can choose SmartVIN to detect your vehicle automatically. However, you choose Manual Selection if SmartVIN does not work as intended.
- Select the Specific Model and Chassis: After selecting the vehicle make, scroll through the available models and select the correct one for your Lamborghini. Choose the corresponding chassis or body type to properly sync the scanner to your vehicle.
- Select Control Units: Once you have selected the model and chassis, the scanner will let you choose between “Quick scan” or “Control Modules”. Control Modules display a list of control units or modules in your vehicle. Examples include the engine control module (ECM), transmission control module (TCM), and ABS control module. Choose the specific module you want to diagnose. Otherwise, you can also choose the “Quick Scan” to check everything.
- Interpret the Codes: Once the YOUCANIC scanner completes the code retrieval process, the displayed codes will provide information about specific issues detected by the control unit. Take note of these codes for further analysis and diagnosis. Each DTC consists of a letter and four numbers. The letter indicates the system affected, while the numbers describe the issue more specifically. Click here to learn more about fault codes.
- Erase Codes: After the problem has been repaired, return to the scanner’s menu and select the option to “Erase Codes” or “Clear Codes.” This action removes the stored fault codes from the control unit’s memory, indicating that the problem has been resolved. Please note that you may or may not erase a code when the issue is not fixed.

When should I scan?
Regularly scanning your Lamborghini for DTCs is akin to giving your vehicle a check-up. It’s recommended to scan your car at least once a year, or more frequently, if you notice any performance issues or warning lights illuminating, which includes SRS, ABS, Differential, Transmission, Traction control, etc.

Why doesn’t clearing the codes always work?
Once you’ve identified the DTCs, you may be tempted to clear them, hoping to continue driving your Lamborghini, and the problem magically disappears. While clearing the codes can temporarily remove the “Check Engine” light, it doesn’t address the underlying issue. It will always come back. Here are also some lists of why you cannot clear the codes of your Lamborghini:
- Use a Professional-Grade Scanner: Ditch the generic scanner and upgrade to a professional-grade one like the YOUCANIC scanner. Generic scanners are like trying to open a Ferrari with a Ford key – it won’t work! YOUCANIC, on the other hand, is like the master key to your Lamborghini’s diagnostics, unlocking hidden diagnostic powers and letting you clear codes that would otherwise remain stubborn and hidden.
- Underlying Issues: Before clearing fault codes, remember to address the underlying issue that triggered them in the first place. Clearing codes is like patching a leaky pipe without fixing the cracked valve – it’s just a temporary fix. The ‘check engine’ light will surely come back and haunt you.
- Continuous Fault Monitoring: Like the SRS system, certain fault codes may be cleared by disconnecting the battery (like a reset). They will reappear even after clearing until the root cause is resolved. It is a persistent reminder to fix the problem, not just mask it.
- Proper Clearing Procedure: Following the correct steps outlined in your diagnostic scanner’s user manual is essential to clear fault codes effectively. If unsure about the clearing procedure, consult a professional for guidance specific to your scanner and Lamborghini model.
What do historical, current, and stored DTCs do?
- History: These codes indicate past issues that have resolved themselves or are no longer causing the “Check Engine” light to illuminate. They typically do not require immediate attention.
- Current Codes: These codes represent the current or active problems that require immediate diagnosis. It indicates a present issue or malfunction in a specific system or component of the vehicle that needs to be addressed. They will remain displayed until the underlying issue is resolved.
- Stored Codes: These codes are inactive but remain stored in the computer’s memory, recording previous issues. These can provide additional information about past issues as a historical reference for previous faults. While they may not be active, they can offer insights into the vehicle’s history and aid in the diagnostic process.

What is the purpose of Live Data and Freeze data?
Live data allows you to monitor real-time sensor readings, providing valuable insights into the car’s operation. On the other hand, Freeze frame data captures a snapshot of vehicle conditions when a fault code is triggered. Analyzing this data provides context and aids in pinpointing the root cause of the issue.
Frequently Asked Questions
Can I clear DTCs myself?
Yes! While clearing DTCs can temporarily turn off the “Check Engine” light, it doesn’t address the underlying issue. It’s recommended to have a qualified mechanic diagnose and repair the problem first before you clear all the codes. You can also ask for professional assistance.
How Often should I check for DTCs?
Regularly checking for DTCs can help you identify potential issues early on, preventing more serious problems. You can also use it whenever a check engine light illuminates to diagnose or check why your car is acting up.
What are the benefits of using a professional-grade scanner?
Professional-grade scanners provide more detailed information, manufacturer-specific codes, guided diagnostics, and component testing capabilities, making them a valuable tool for accurate diagnosis and repair.
