In this article, we embark on a journey into the world of Lancia, where we’ll unveil the techniques to read and clear fault codes from all Lancia models. Moreover, we’ll explore the intricate task of diagnosing issues across control units such as the Engine Control Module (ECM), Transmission Control Module (TCM), Anti-Lock Braking System (ABS), and many more – a vital process to decode those cryptic dashboard warnings and ensure your Lancia continues to grace the road with its Italian excellence. So, fellow Lancia enthusiasts and troubleshooters, let’s dive into deciphering your beloved vehicle’s secrets, one control unit at a time.
Reading Lancia DTCs/Fault Codes
OBD stands for “On-Board Diagnostic”. Most modern vehicles now include an OBD port, which can be utilized by a scanner that communicates to your vehicle. It is plugged in by an OBD-II scanner into the socket designed to help automotive technicians interpret faults and other issues that your Lancia may be experiencing or have recorded. 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 Lancia. 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 Lancia 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.
- Turn on the ignition, but do not start the engine.
- 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 Lancia.
- Select ‘Lancia’ as the Vehicle Make: This ensures the scanner effectively communicates with the Lancia 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 Lancia. 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.

I can’t clear the Fault codes.
Once you’ve identified the DTCs, you may be tempted to clear them, hoping to continue driving your Lancia, 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 Lancia:
- Use a Professional-Grade Scanner: Ditch the generic scanner and upgrade to a professional-grade like YOUCANIC. 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 Lancia’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 ABS, 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 Lancia model.
What Happens When I Ignore Fault Codes?
Ignoring DTCs can lead to a cascade of issues.
- Performance: Over time, unaddressed faults can lead to decreased performance, reduced fuel efficiency, and increased emissions.
- Safety Hazard: Ignored DTCs can pose safety risks, particularly related to critical systems like brakes or airbags.
- Costly Repairs: Putting off repairs can result in more extensive damage, such as damage to your transmission, leading to higher repair costs in the long run.
