How to Connect My Scan Tool

Vehicles are equipped with an internal computer module. When a component begins to fail within your vehicle, the computer sends a code to illuminate the “Check Engine” light on the instrument panel. This alerts the driver that there is a problem that must be addressed immediately. To learn what code is causing the problem and what the code stands for, you must have a scan tool. The scan tool hooks up to the computer connector and reads the codes. It’s important to learn how to properly connect the scan tool to ensure you can diagnose and fix your vehicle.

1.Plug the connection cable into the scan tool. The cable comes with the tool and plugs into the bottom of the unit.

2.Locate the vehicle DLC connector. The connector is found under the vehicle dash on the driver side of the steering wheel column for regular vehicles. For heavy-duty vehicles, the connector is found behind the driver side kick panel. Lift the kick panel out towards you and you will see the connector.

3.Plug the cable from the scan tool into the connector. You will hear the cable click into place. The scan tool is now connected and ready for use. Follow the manufacturer’s instructions on using the specific scan tool.

How to Reset the Error Message on a Mercedes Benz

Error codes on your Mercedes allows you to find specific issues on the vehicle that should be fixed. Sometimes after the device has been fixed you may have error codes won’t erase. Removing the battery terminal to reset the error message will not fix the problem and may cause strain on your fuses. Purchasing a code scanner from your local auto supplies store or website will help manually remove the error code. If you erase the error code before the problem is fixed, the error code may return at a later time.

1.Purchase a 16pin OBD11 scanner, which will connect to your Mercedes and list current error codes. If your Mercedes was manufactured before 1994, you may have a 38 pin socket, which requires you to purchase a 38 pin scanner instead. Code scanners can be found on sites like eBay, Amazon and

2.Connect the OBD11 scanner into the port which should be located near the steering wheel by the dash. Each model Mercedes-Benz may have the connector port in different locations so refer to your owner’s manual.

How to Select a Professional Mechanic OBD2

OBD2 readers are available as simple handheld readers with basic features and professional scan tools with advanced functions. While the simple readers are adequate for car owners who just want to understand their vehicles better, the professional mechanic needs a tool that will identify problems quickly, accurately and with as much detail as possible.

Select Your OBD2 From Available Categories
1.Select professional mechanic software for desktop and laptop computers. Among the advantages of using a computer as an OBD2 scan tool is the large amount of space available to save the Diagnostic Trouble Codes, a large screen for easy viewing, relatively low cost, reprogramming capability, the ability to upgrade easily and a large selection of OBD2 software. The main disadvantage is that these computers will be difficult to carry around the car while you work.

2.Use your Pocket PC as an OBD2 reader. The portable nature of this type of OBD2 reader, as well as its low battery power consumption, will enable the professional mechanic to work around the car with the diagnostic information in hand. There is OBD2 software for Palm handheld computers also.

3.Increase productivity with a wireless interface. OBD2 scan tools equipped with wireless cards eliminate the need for cables and make it possible for the mechanic to scan the car from a distance.

4.Select a stand-alone, handheld scanner. This type of OBD2 reader obtains the Diagnostic Trouble Codes quickly and, in some cases, will display the definition of the codes on the screen. Unlike computer-based OBD2 readers, there is no need to install a program or learn to use the equipment.

Select the Features of an OBD2 Reader
1.Choose a professional OBD2 reader that can clear the codes. Once the problem has been determined, most readers can erase the report from the car’s system and turn off the warning light on the dashboard.

2.Select a professional grade OBD2 reader that can read freeze frames.

3.Consider a reader that will work on as many car models as possible. OBD2 readers are designed to use one or more of the five communication protocols that are specific to certain types of cars. These protocols are: SAE J1850 PWM used for cars manufactured by Ford Motors, SAE J1850 VPW used by General Motors, ISO 9141-2 used in Chrysler cars as well as in Asia and Europe, the ISO 14230 KWP2000 and the ISO 15765 CAN.

4.Choose a reader that can perform most of the diagnostic functions. These functions include the ability to read and clear codes, display code definitions and part identification numbers, auto-scan, perform an actuator test and perform programming functions.

How to Wire a Volt Meter in a Car

Driving a car requires an immense amount of responsibility. Keeping your eyes on the road and being aware of the traffic is only half of the job. A driver also needs to monitor the vehicle’s performance. Interpreting what the engine is saying to you through its movements and sounds is also a function of a responsible driver. Fortunately, there are a few quality aftermarket suppliers that help make engine monitoring easier. For example, a good way to find out the status of your car’s charging system is to wire a volt meter into the system.

Apply the parking brake. Open the hood. Remove the battery ground cable by loosening the retaining bolt with a wrench.

Mount the gauge. Open your gauge package and inspect the contents. You will have the volt meter gauge, the gauge housing (mounting bracket), mounting hardware, wire and the directions. Read the directions on mounting the gauge. Find a location to place the gauge where it can be easily seen (along the bottom of the dash is often the best). Hold the housing against the dash and place a self-tapping screw through the mounting hole. With a screwdriver bit locked into the drill motor, drive the screw in until it is tight. Repeat this process for the other mounting hole.

Wire the positive side of the gauge. Run the positive wire from the gauge through the fire wall. The fire wall is the part of the vehicle’s body that separates the passenger compartment from the engine bay (underneath the dash board). Slide the wire through an existing grommet and connect it to the positive battery terminal by stripping the end of the wire with a wire stripper and crimping on a terminal end (included in the mounting kit). Connect this terminal to the positive battery post and tighten with a wrench.

Wire the ground side of the gauge. Run the ground wire from the gauge to the engine block. Run the wire through the same grommet in the fire wall and strip the end of the wire with the stripper. Crimp a terminal end onto the wire with the crimping pliers. Fasten this wire to the engine block by loosening a bolt, inserting the terminal on the bolt and tightening it with your wrench.

Reconnect the battery. Place the negative cable back onto the battery and tighten it with a wrench. Close the hood.Want to learn more knowledge, you can come

How to: Auto Diagnostic Testing

The advent of On Board Diagnostics (OBD) in the automobile manufacturing industry 15 years ago has made diagnosing car trouble much easier for the layperson. Now every new car is equipped with a readable OBD system that delivers information as a series of codes. When a trouble code comes up, the “check engine” light will ignite on the dashboard, indicating to the owner that the car has a problem. With a bit of research, you can use your car’s computer diagnostics to diagnose and fix car problems.

Borrow an OBD-II scanner from your local auto parts store. Most national auto parts companies, such as Murray’s and O’Reilly’s, will lend OBD-II scanners. You’ll need to leave collateral like a driver’s license or credit card while you take the scanner out to work on your car in the parking lot.

Plug the OBD-II scanner into your car’s Data Link Connector (DLC). The DLC is usually located below the driver’s-side dash, just left of center. It has 16 connection points and should match the cord included with the OBD-II scanner. If you cannot find it, refer to your car owner’s manual or contact the manufacturer. Your car must be on, but don’t start the engine.

Turn on the scanner and follow the on-screen instructions. The scanner may generate generic codes and manufacturer’s specific codes. Generic codes are the same for every automobile. Consult the online guide for generic OBD codes to determine the problem. The OBD-ll scanner can’t read manufacturer’s codes .If your car is showing a manufacturer code, take it to your local dealership shop to determine the specific problem.

Consult with your mechanic once you’ve retrieved your car’s trouble codes. She can discuss the various repairs needed for your car’s problem.
