Published on Mar 22, 2024 by Boulder Service Team

An Inside Look at Boulder Nissan's Diagnostic Service

Have you experienced unusual noises, warning lights, or performance issues? Unforeseen issues can arise that require diagnostic attention, regardless of diligent upkeep. In this article, we'll take you behind the scenes to explore steps Boulder Nissan takes to diagnose issues with your Nissan. 

Initial Assessment

You will enter our service department for your appointment. One of our service advisors will greet you and ask for details regarding your concern. The more information you can provide us, the better. These details will be noted and printed on the repair order for the diagnosing technician. 


It's important to note that our service department does charge for diagnosis; however, we recognize that each diagnostic situation is unique, so we offer variable pricing. 

Your advisor will gather information, recommend the best route of diagnostic tests, and authorize the cost with you before starting our diagnosis process. Our diagnosis charge reflects the expertise and time invested by our certified technicians in thoroughly assessing and identifying the root cause of any concerns with your Nissan. This charge covers the cost of pulling diagnostic codes, conducting comprehensive inspections, and dedicating the necessary time and resources to pinpoint the issues affecting your vehicle's performance. By investing in our diagnostic services, you're not only compensating our technicians for their skilled labor but also ensuring that your vehicle receives the attention it deserves. Ultimately, this upfront charge enables us to provide you with accurate diagnoses and tailored repair solutions, saving you time, money, and hassle in the long run. We believe in transparency and value our customer's trust, which is why we're upfront about our diagnosis charge and the valuable services it encompasses.

Diagnostic Testing

What happens once diagnosis time is authorized and the RO (repair order) is written and dispatched to the diagnosing technician? 


We start by connecting a computer named Consult to the onboard diagnostic port of the vehicle. OBD collects and stores information from the vehicle's sensors. Consult allows a technician to access stored codes and provide insight into the issue we are diagnosing. Codes do not always identify the problem but can point us in the right direction.

Visual Inspection

Following the retrieval of diagnostic codes, our technicians at Boulder Nissan proceed with a visual inspection and targeted testing based on the identified codes. This focused approach allows our technicians to hone in on specific areas of concern indicated by the codes. They meticulously examine the corresponding components of your Nissan vehicle, assessing for any visible signs of wear, damage, or irregularities that correlate with the reported symptoms.


Additionally, our technicians utilize specialized diagnostic tools and instruments to conduct further tests directly related to the codes retrieved. By integrating insights from both the visual inspection and targeted testing, we can efficiently identify which parts or components are contributing to the issue at hand and devise a precise repair plan to address them promptly. 

Consultation and Estimate

After completing the diagnosis process, our technician documents their findings and the recommended repairs to resolve the identified issue on the repair order. This includes detailing the specific parts or components that require attention and outlining the necessary steps to address the problem effectively. Once these recommendations are documented, the technician explains this to the service advisor to relay this information to the customer clearly and understandably. The service advisor acts as a bridge between the technical aspects of the diagnosis and the customer's understanding, ensuring that all recommended repairs and their implications are communicated accurately.

Additionally, the technician and service advisor work together to establish an estimate for the cost of repair, taking into account factors such as labor, parts, and any additional services required. By combining their expertise and insights, our team strives to provide transparent and comprehensive information to our customers. 


From the initial assessment and diagnostic code retrieval to the visual inspection and collaborative efforts between our skilled technicians and service advisors, every step is taken with care to ensure the accurate identification of issues affecting your Nissan.


We understand the importance of transparency and communication in the service experience, which is why we strive to keep our customers informed every step of the way. Whether you've encountered unusual noises, warning lights, or performance issues, you can trust Boulder Nissan to provide reliable diagnosis and tailored repair solutions to keep your Nissan running smoothly for miles to come. Thank you for joining us on this journey behind the scenes of our diagnosis process, and we look forward to serving you and your vehicle.
