You are required to have a emission inspection performed on your vehicle if you are planning on registering it in the state of Texas. We can perform this state inspection and provide you with the needed paper work to register your vehicle. You will need to show proof of insurance at the time of the inspection. If your vehicle has a Check Engine Light on your vehicle will fail inspection and will need to be diagnosed by the technician and additional diagnosis fees will apply. Your service consultant will advise you if this is the case. The most common misconception we hear about regarding Check Engine Lights (or Service Engine Soon lights) is that you must pull the car over right away and stop driving.
This is not entirely true. The check engine light is an emissions-related light that indicates a potential problem with your car. The ECU (vehicle’s computer system) stores over 200 different codes that could set off that light. The proper way of diagnosing the light is to hook the vehicle up to a diagnostic scanner such as what we use here, a Snap-On Modis. This scanner communicates with your vehicle’s ECU and retrieves that particular code(s). That code is just the beginning of a diagnostic flowchart which we must follow to test certain parameters of a part or sensor. You can still drive the car, but get it checked out soon. Texas Law now automatically fails your annual inspection if this light is on.
