Saab, a Swedish automaker known for its innovative and stylish vehicles, utilizes Diagnostic Trouble Codes (DTCs) to identify and diagnose potential issues within its vehicles. These codes, standardized by the Society of Automotive Engineers (SAE), provide valuable insights into the health of various vehicle systems, enabling technicians to effectively troubleshoot and repair faults.
When these glitches or malfunctions arise, your Saab’s engine may start showing warning lights such as ABS, SRS, Transmission temperature, Oil pressure, battery charging, Differential, Traction control, check engine light, etc. Now these lights mean something, they are saved in your vehicle’s On-Board Diagnostic where an OBD-II Scanner is used to interpret and ready the codes. Fear not, for this guide will illuminate the path to deciphering these perplexing codes and unlocking the knowledge of fault codes and how to access them.
Understanding and addressing these codes is crucial for maintaining your Saab’s top form and ensuring a smooth ride down the road.

Reading and clearing your Saab’s codes
- Gather the necessary tools: Equip yourself with a Professional-Grade OBD-II Scanner that is compatible with your Saab. Click Here for our Professional-Grade YOUCANIC Scanner
- Access the OBD-II Port: This port is usually found under the dashboard, near the steering column, 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 Saab 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 Saab.
- Select ‘SAAB’ as the Vehicle Make: This ensures the scanner effectively communicates with Saab’s 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 Saab. Additionally, 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 opt to 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 take note that you may or may not erase a code when the issue is not fixed.

OBD stands for “On-Board Diagnostic”. Most modern vehicle now includes 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 Saab may be experiencing or have recorded. All Saab have an OBD-II port, some common models include 9-5, 900, 9-4x, 9-3, 9-7x, 9-2x, and many more.
DIY as an Enthusiast or consult a mechanic, make the right choice
Whether to tackle DTCs yourself or seek professional assistance depends on your mechanical aptitude and the issue’s complexity. If you’re a seasoned DIY enthusiast with a well-stocked toolbox, you might be able to handle minor issues. However, for more intricate problems, it’s wise to entrust your Saab to the expertise of authorized Saab technicians.
Decoding the Enigma of DTCs
DTCs are standardized codes that follow a specific format, providing valuable insights into the nature of the problem. The first character indicates the type of system (P for powertrain, B for body, C for chassis, and U for network comm.), followed by four digits. The first digit identifies the system, the second digit denotes the subsystem, and the last two digits pinpoint the specific fault.
For instance, a DTC starting with P01 would indicate a powertrain issue related to fuel or air metering. Further, a code like P0171 would point to a lean air-fuel mixture.
Why Should I Scan My Vehicle?
Regular scanning offers several benefits:
- Early Detection of Issues: DTCs can alert you to potential problems before they cause noticeable symptoms, allowing for timely intervention.
- Improved Fuel Efficiency: Addressing underlying issues can enhance fuel economy, saving you money at the pump.
- Extends the Vehicle Lifespan: Promptly addressing faults can prevent further damage and prolong your Saab’s lifespan.
Regular scanning as a preventive checkup for your Saab is like going to your doctor’s visit annually. Your Saab deserves regular attention to keep it running smoothly and safely. If you want to learn more about the Check engine light of your Saab, click here.
I can’t clear the error codes of my Saab, why?
Once you’ve identified the DTCs, you may be tempted to clear them, hoping to continue driving your Saab 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 Saab:
- Use a Professional-Grade Scanner: Ditch the generic scanner and upgrade to a professional-grade one 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 Saab’s diagnostics, unlocking hidden diagnostic powers and letting you clear codes that would otherwise remain stubborn and hidden.
- Underlying Issues: Before you go 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: Certain fault codes, like the SRS system may be cleared by disconnecting the battery (like a reset). They will reappear even after clearing until the root cause is resolved. Think of it as 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 Saab model.
