Since 1996, all Ford Contours have been equipped with the OBD-II system, allowing you to diagnose vehicle issues by reading diagnostic trouble codes (DTCs) using an OBD-II code reader. This article provides a detailed guide on how to retrieve these codes, interpret them, and understand what they mean for your vehicle's health.
The On-Board Diagnostics II (OBD-II) system is a standardized system in vehicles that monitors various engine and vehicle functions. When a problem is detected, the system triggers the Malfunction Indicator Light (MIL), commonly known as the check engine light. The OBD-II system then stores a diagnostic trouble code (DTC) that can be read using a code reader or scanner.
The DLC is typically found under the driver's side dashboard near the steering wheel. It is trapezoid-shaped, and you can identify it by matching it with the plug on your code reader.
Insert the OBD-II scanner into the DLC. Turn the ignition key to the "key-on/engine-off" position, which is two clicks clockwise. This powers up the scanner without starting the engine.
Once connected, the scanner will power up using the vehicle's battery. Follow the onscreen menu, which usually includes an "enter" button and up/down scrolling buttons.
Scroll through the menu until you find the "read codes" option. Press the enter button. The scanner will display the codes or indicate how many codes were found. Follow the onscreen instructions to read all the trouble codes, including pending ones.
Write down the error codes displayed by the scanner. Use an OBD-II DTC chart to interpret these codes. Note that not all codes will pinpoint the exact problem; further investigation may be required.
While the OBD-II system is highly effective, it may not always provide a clear diagnosis. Some issues may require professional evaluation or specific repairs. For more detailed information, you can refer to OBD-II Codes for a comprehensive list of trouble codes and their meanings.
Retrieving and interpreting OBD-II trouble codes on your Ford Contour is a straightforward process that can save you time and money. By following this guide, you can diagnose potential issues early and take appropriate action. For more detailed diagnostics, consider consulting a professional mechanic.
