XENTRY computer diagnostics are a tool that allows you not only to see what the problem is but to see functional targets as well. The XENTRY system is designed to help guide the repair process, suggesting what needs to be done and how to perform post-repair checks to make sure problems are really resolved. Like other computer diagnostic tools, XENTRY also works to identify unknown problems so that they can also be handled before becoming a bigger issue.


OTIS is the diagnostic tool primarily used by the Volkswagen Group and is important for monitoring the condition of VW and other Volkswagen Group vehicles, as well as for finding unknown problems and getting repair and testing procedures from VW vehicle computers. OTIS is one of the more difficult systems for many mechanics to get, in part because it’s often not compatible with non-OEM scanning systems, so VW drivers who want to access their own vehicle’s computer codes may need an OTIS-specific scanner.


Autel is a bi-directional diagnostic and calibration tool that can provide a lot of useful information about a vehicle’s functioning, current, and future needs, and how to go about addressing problems. It’s also one of the faster systems, and able to process a lot of information quickly and provide the repair info you need on-screen. One of AUTEL’s strengths is that this system can provide live updates of data, so you’re getting a continuous picture instead of short snapshots of what’s going on and how the vehicle is performing.


OBD stands for On-Board Diagnostic, and there are both OBD and OBD2 scanners available. For the most part, these are universal scanners that can quickly identify and translate computer codes for faster problem identification when you’re getting an alert. These scanners are available for both professional and home use and are sufficient for the vast majority of car systems and problems.


Your vehicle’s check engine light is one of the more misunderstood alert systems included in your vehicle. It’s an indicator that something is wrong with the engine’s emissions system, and, depending on the nature of the problem, may flash, come on for a while and then turn off randomly, or come on and stay on until the problem is resolved. No matter how the check engine light appears, a code related to the problem will generate and be stored in your vehicle’s computer. The code is still available even after the check engine light goes out, which is part of how your mechanic or an auto parts store can tell what happened even if the light isn’t on. Check engine lights coming on aren’t always the end of the world, but they do mean you should get your vehicle to a mechanic soon, or at least pull out a scanner and see if you can fix the problem yourself. Is your check engine light on? Bring your vehicle to Precision Auto Care and we’ll be happy to diagnose and repair the problem. Call or email for your appointment, today.
