If you're seeing a code that looks like "93" on your Cadillac's dashboard, it's likely:
* A manufacturer-specific code: Cadillac, like other manufacturers, might use codes outside the standard OBD-II range for their own internal diagnostic purposes. These codes require looking up in a Cadillac-specific diagnostic manual or using a professional-grade scan tool that can interpret Cadillac's proprietary codes.
* A misreading: Double-check the code displayed on your vehicle's dashboard to ensure you're reading it correctly. Even a single incorrect digit will lead to an incorrect interpretation.
* A problem with the diagnostic system itself: There's a chance there's a malfunction within your vehicle's onboard diagnostics system, leading to an erroneous code being displayed.
To get the correct diagnosis:
1. Get the full code: Make absolutely sure you have the complete code displayed.
2. Use an OBD-II scanner: A scan tool, preferably one that can read Cadillac-specific codes (more advanced scanners often have this capability), will give a more accurate and detailed description of the problem.
3. Consult a Cadillac mechanic: A qualified mechanic will have the tools and knowledge to properly diagnose and fix the issue. Simply providing a code like "93" is insufficient for accurate troubleshooting.
