Preferred On-Site Fleet Services of Texas understands the importance of your On-Board Diagnostics. Give us a call or stop by for a complete diagnostic check up:

Check Engine Light
No one likes to see their truck's "Check Engine" light come on. The light could mean a costly problem, like a bad catalytic converter, or it could be something minor, like a loose gas cap. At Preferred On-Site Fleet Services of Texas, we can pull the code and diagnose the problem for you. Give us a call at 903-630-7999 or stop by the shop for our expert assistance.

Computer Diagnostics
Modern fleets are fitted with at least one onboard computer. The computer's main function is to monitor and adjust the engine and transmission. Computer testing and diagnostics is an integral aspect to professional electronic work on modern fleets. Computer diagnostics help find the root causes of major and potential automobile problems. At Preferred On-Site Fleet Services of Texas, we have state of the art computer diagnostics equipment such as digital code readers, pressure test kits, circuit testers, digital tachometers and more. We use Texa diagnostics. Call 903-630-7999 or visit our fleet shop in Tyler, TX 75705 for all your truck's computer diagnostic needs.

Drivability
Drivability is the degree of smoothness and steadiness of your truck's acceleration. Most modern trucks are fitted with on-board computers that continuously check the readings from various sensors. In case of drivability problems, you will receive a warning message on your truck's dashboard. To have your truck diagnosed for drivability issues, visit Preferred On-Site Fleet Services of Texas in Tyler, TX 75705 today. At Preferred On-Site Fleet Services of Texas, we have the necessary tools, training, and technology to diagnose and address your truck's drivability issues.

Engine Controls
Basically, an engine control system is an on-board computer in your truck. Like all computers, the engine controls are composed of hardware and software. Automotive engine control systems are responsible for regulating exhaust emissions, and providing increased fuel economy. To get the best out of your truck's incredibly powerful technology, make sure engine controls are working properly. To check if your truck's engine controls are working properly, call Preferred On-Site Fleet Services of Texas today.

Friendly staff. Professional fast service. Don't take your truck to the dealer and wait two weeks for over priced repairs! Preferred has well qualified, knowledgeable, experienced mechanics that get the work done in less time at a lower cost. Their on-site repairs avoid towing delays and costs. I have been a customer for several years and have never been disappointed by the service received! Their new location has plenty of room for your truck and trailer and multiple bays to get the work done. Their driver waiting area has comfortable seating, tv, and free snacks as always. You get to talk with the mechanic doing the work if desired without a service advisor blocking direct communication. Drivers are treated with respect rather than as a burden. It's quite clear that the owner takes pride in delivering personal quality service to his customers.
