Understanding Diagnostic Trouble Codes (DTCs)

DTCs are codes that the car’s computer system generates to indicate a problem. They consist of a five-digit alphanumeric code.

For example, the code P0301 means:

P: Powertrain (Engine, Transmission, or Emissions)
0301: Cylinder 1 Misfire Detected

Understanding DTCs can help you pinpoint the source of your car troubles and take appropriate action.

Common Issues and Troubleshooting

While the Craftsman OBD2 47156 is generally reliable, you might encounter some issues:

Scanner won’t power on: Check the connection to the OBD2 port and ensure the ignition is on.

Tips for Using the Craftsman OBD2 47156

Always consult your car’s service manual in conjunction with the information provided by the scanner.
