Types of Auto Diagnostic Scanners

A vehicle's dashboard contains a multitude of warning lights. This includes a general "Check Engine" light, as well as malfuction indicators for antilock brakes, tire pressure monitoring sensors, and air bags. Each of these CMS600A B-Ultrasound Diagnostic Scanner 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 hook up to the same outlet in a vehicle.Using an on-board diagnostics (OBD) code reader depends on the year a vehicle was manufactured. 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 B-Ultrasound 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 broken.

Some scanners may be compatible with other diagnostic systems, 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 Sonoline C Pocket Fetal Doppler , it is wise to consider the vehicles it can be used with and make certain the hardware is compatible.Tire pressure monitoring systems (TPMS) are not widely used as OBD-II codes, but soon will be. The Department of Transportation has mandated that all cars manufactured after 2008 be equipped with TPMS sensors. Although these monitors are no substitute for regularly checking tire pressure by hand, they can give a driver ample warning that there is a problem with a tire, which can help avoid a flat or a blowout. A TPMS scanner works very much the same way as OBD-II and ABS code readers. It interacts with a vehicle's computer, reads the trouble code, and can lead to a diagnosis.

Air bags operate under the supplemental restraint system (SRS). Diagnostic tools for SRS trouble codes are scarcer than ABS readers. Of the few that are available, they tend to be specific to manufacturers, like BMW. Also, like the braking system, if there is a problem with air bags, it's best to leave the repair work to a trained professional. Air bags can require complex maintenance and be costly to fix, so reverse engineering a casual mistake can become expensive.CMS600E B-Ultrasound Diagnostic Scanners with a laptop allows for easier updating and upgrading as coding changes.Technology develops at a pace that favors integration. Some day, diagnostic code scanners may become all-in-one tools. So instead of owning several readers, a home mechanic would have one tool for OBD, ABS, TPMS and other trouble codes. There are already several scanners that can multitask. Actron's CP9580 Auto Scanner, for example, can read both OBD and ABS codes. Presently, the more expensive the piece of hardware, the more access to vehicle diagnostics. Also, there is a way to bypass scanners altogether. A home mechanic can buy and download software packages and turn a laptop into a multilingual scan tool. However, a diagnostic cable with both a USB and a 16-pin data link connector would have to be purchased separately.

No matter the diagnostic system, interfacing with a vehicle's diagnostic system requires access to the data link connection (DLC) in a vehicle. The only exception to this is with certain SRS CMS600B-3 B-Ultrasound Diagnostic Scannerscanners that require opening the vehicle's hood and locating a special 20-pin outlet. 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 code.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.
