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 John's Automotive, we can pull the code and diagnose the problem for you. Give us a call at 818-705-2288 or stop by the shop for our expert assistance.

Computer Diagnostics
Modern vehicles 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 cars. Computer diagnostics help find the root causes of major and potential automobile problems. At John's Automotive, we have state of the art computer diagnostics equipment such as digital code readers, pressure test kits, circuit testers, digital tachometers and more. Call 818-705-2288 or visit our auto shop in Tarzana, CA 91335 for all your vehicle's computer diagnostic needs.
