Steering Angle Sensor (DAS) calibration is a critical procedure for many modern vehicles, especially those equipped with advanced driver-assistance systems (ADAS). The 2017 Infiniti Q50, with its innovative Direct Adaptive Steering (DAS) technology, is no exception. This article delves into the intricacies of DAST calibration on the 2017 Infiniti Q50, highlighting its importance and the role of a professional scan tool in ensuring accurate execution.

Understanding DAST and Its Calibration Needs
The 2017 Infiniti Q50’s Direct Adaptive Steering (DAST) system represents a significant leap in automotive steering technology. Unlike conventional systems that rely on mechanical linkages, DAST utilizes electronic signals to transmit steering inputs from the driver to the wheels. This results in a more responsive and customizable driving experience. However, this sophisticated system necessitates precise calibration to ensure optimal performance and safety.
DAST calibration involves aligning the steering angle sensor with the vehicle’s electronic control unit (ECU). This alignment process ensures that the ECU accurately interprets the driver’s steering inputs and translates them into precise wheel movements. Several factors, including wheel alignment, suspension modifications, or even software updates, can necessitate DAST calibration.
When Does Your 2017 Infiniti Q50 Need DAST Calibration?
Recognizing the signs of miscalibration is crucial for maintaining your vehicle’s handling and safety. Common indicators include:
- Illuminated Warning Lights: A persistent illumination of warning lights related to the steering system, traction control, or vehicle dynamic control (VDC) may signal a DAST calibration issue.
- Steering Wheel Off-Center: If you notice the steering wheel is not centered when driving straight ahead, it’s a strong indication that DAST calibration is required.
- Erratic Steering Response: Experiencing inconsistent steering feedback, such as the vehicle pulling to one side or feeling unstable during turns, may warrant immediate attention and potential DAST calibration.
- Recent Servicing: Any work performed on the steering system, suspension components, or wheel alignment necessitates a subsequent DAST calibration to maintain proper system communication.
The Importance of Using a Scan Tool for DAST Calibration
While some minor calibration adjustments might be possible without specialized equipment, attempting to calibrate the DAST system on a 2017 Infiniti Q50 without a professional-grade scan tool is strongly discouraged. Here’s why:
- Precision and Accuracy: DAST calibration involves intricate adjustments that require a high degree of precision. Professional scan tools provide the necessary accuracy to ensure the steering angle sensor is perfectly aligned with the ECU, preventing potential safety hazards.
- Access to Advanced Functions: Scan tools designed for vehicles like the Infiniti Q50 offer access to manufacturer-specific functions and data streams essential for DAST calibration. These tools can read and clear diagnostic trouble codes (DTCs) related to the steering system, providing valuable insights into the calibration process.
- Streamlined Procedure: Utilizing a scan tool simplifies the DAST calibration procedure, guiding technicians through a step-by-step process and minimizing the risk of errors.
- Software Updates and Compatibility: Regular software updates are crucial for scan tools to remain compatible with the latest vehicle models and their evolving technologies. Ensuring your scan tool is up-to-date guarantees access to the most recent calibration procedures and data parameters for your 2017 Infiniti Q50.

Finding the Right Scan Tool for 2017 Infiniti Q50 DAST Calibration
Selecting the appropriate scan tool is paramount for successful DAST calibration. Consider these factors when making your choice:
- Vehicle Compatibility: Ensure the scan tool explicitly states its compatibility with the 2017 Infiniti Q50 and its specific systems, including DAST.
- Functionality: Opt for a scan tool that offers comprehensive functionality beyond basic code reading and clearing. Look for features such as bi-directional control, live data streaming, and access to manufacturer-specific functions for the Infiniti Q50.
- User-Friendliness: Choose a scan tool with an intuitive interface and user-friendly software that simplifies the calibration process and makes it accessible to both professionals and experienced DIYers.
- Updates and Support: Regular software updates are crucial for scan tools. Opt for a reputable brand that provides ongoing software updates to ensure compatibility with the latest vehicle models and technologies.
Conclusion
DAST calibration is not a procedure to be taken lightly. It is crucial for the safe and optimal performance of your 2017 Infiniti Q50. While the allure of DIY solutions may be tempting, using a professional-grade scan tool is the only way to ensure accuracy, safety, and long-term reliability. By understanding the importance of DAST calibration and choosing the right equipment, you can confidently maintain your vehicle’s performance and enjoy a smooth, responsive driving experience.
FAQs
1. How often should I calibrate the DAST system on my 2017 Infiniti Q50?
Infiniti recommends DAST calibration after any service involving the steering system, suspension, or wheel alignment. It is also good practice to have it checked annually or if you notice any of the warning signs mentioned above.
2. Can I drive my 2017 Infiniti Q50 if the DAST system needs calibration?
While you might be able to drive for a short distance, it is strongly advised against continuing to drive with a miscalibrated DAST system. Doing so can compromise vehicle handling, potentially leading to safety hazards.
3. How long does the DAST calibration process typically take?
The duration can vary depending on the specific scan tool and the technician’s experience. However, it generally takes less than an hour to complete the procedure.
