2. How Does the Craftsman OBD2 Scanner Model 47156 Work?

The Craftsman 47156 works by accessing the vehicle’s onboard computer system. When a problem is detected, the computer stores a DTC, which the scanner retrieves and displays. The scanner uses standardized protocols to communicate with the vehicle, ensuring compatibility across different makes and models.

2.1 The OBD2 Protocol

The OBD2 (On-Board Diagnostics II) protocol is a set of standards for monitoring and diagnosing vehicle systems. Mandated in the United States since 1996, it ensures that all vehicles provide standardized diagnostic information. The OBD2 system monitors various components, including the engine, transmission, and emissions systems, and reports any detected issues through DTCs. According to the EPA, the OBD2 system helps reduce emissions and improve fuel efficiency by enabling early detection and repair of vehicle problems.

2.2 Connecting the Scanner

Connecting the Craftsman 47156 to your vehicle is straightforward.

1. Locate the OBD2 port, usually found under the dashboard on the driver’s side.
2. Plug the scanner into the port.
3. Turn the ignition to the “on” position without starting the engine.
4. The scanner will power on and begin communicating with the vehicle’s computer.

2.3 Reading and Interpreting Codes

Once connected, the scanner will display any stored DTCs. Each code consists of five characters: a letter followed by four numbers. The letter indicates the system affected (e.g., P for powertrain, B for body, C for chassis, and U for network). The numbers provide more specific information about the problem.

For example, a code like P0300 indicates a random or multiple cylinder misfire. The Craftsman 47156 typically provides a brief description of the code, but you can also consult online databases or repair manuals for more detailed information.

5. Advanced Features and Functions of the Craftsman 47156

Beyond basic code reading, the Craftsman 47156 offers advanced features that can aid in more complex diagnostics.

5.1 Freeze Frame Data Analysis

Freeze frame data captures the vehicle’s operating conditions when a DTC is triggered. This information can help identify the specific circumstances that led to the problem. For example, if a misfire code is triggered at high RPM, the freeze frame data will show the engine speed, load, and other relevant parameters at the time of the misfire. This can help you narrow down the potential causes.

5.2 Live Data Stream Monitoring

Live data stream monitoring allows you to observe real-time data from various sensors. This is particularly useful for diagnosing intermittent problems or monitoring the performance of specific components. By graphing the data, you can identify trends and anomalies that may not be apparent from a static reading. For instance, monitoring the oxygen sensor readings can help diagnose fuel mixture issues, while tracking the coolant temperature can reveal problems with the cooling system.

5.3 Component Testing

Some advanced scanners, including certain models of the Craftsman 47156, offer component testing capabilities. This allows you to activate or deactivate specific components, such as fuel injectors or solenoids, to verify their functionality. This feature requires a good understanding of the vehicle’s systems and should be used with caution to avoid damaging components.

5.4 OBD2 Mode 6 Data

OBD2 Mode 6 data provides detailed information about the performance of individual sensors and components. This data is often used by advanced technicians to diagnose subtle issues that may not trigger a DTC. Accessing and interpreting Mode 6 data requires specialized knowledge and tools, but it can be invaluable for diagnosing complex problems.
