Types of Auto Diagnostic Scanners Mechanics have specialized computers and usually charge diagnostic fees. A vehicle's dashboard contains a multitude of warning lights. This includes a general"Check Engine"light, as well as malfunction indicators for antilock brakes, tire pressure monitoring sensors, and air bags. Each of these diagnostic systems issues a trouble code once a problem is detected. Accessing these codes requires diagnostic hardware, and professional mechanics have a computer for this purpose. For the general public, however, there are smaller diagnostic code readers available. Each of these tools hooks up to the same outlet in a vehicle. On-Board Diagnostics OBD-II covers most engine systems. Using an on-board diagnostics (OBD) code reader depends on the year a vehicle was manufactured autel mx-sensor 315MHz. Vehicles manufactured after 1996 go by OBD-II codes, whereas earlier cars and trucks go by OBD-I codes, and those codes can vary by manufacturer. OBD scanners cover a lot of areas in the vehicle, but particularly the engine and the fuel system. The fault codes can go from the drastic to the easy fix; parts of your engine may need more than routine maintenance or your gas cap might be Always diagnose brake problems immediately. Some scanners may be compatible with other diagnostic systems OBD2 Scanner, but many of the cheaper ones are not. A basic OBD-II scanner will not read codes for antilock braking systems (ABS). While OBD-II scanners cover most vehicles manufactured after 1996, many of the ABS code readers cover only certain vehicles. When researching a possible code reader purchase, it is wise to consider the vehicles it can be used with and make certain the hardware is Pressure Monitoring System Maintaining the right tire pressure will enhance gas mileage. The regular DLC port's location, however, can vary by make and model of the vehicle but is usually located on the driver's side of the vehicle beneath the dashboard between the gas pedal and the trunk release. Once a diagnostic tool is attached, the hardware and the vehicle need to be turned on. The scanner will do the rest and automatically retrieve any awaiting trouble Trouble Codes A scanner's user manual should contain all the generic trouble code definitions as outlined by the Society of Automotive Engineers. Some codes, however, may be specific to a vehicle manufacturer, and definitions will likely not be available in a vehicle's owner manual. There are many websites on the Internet that can assist with finding code definitions, if you have lost your manual or cannot find the information you need.
