How do you extract the diagnose code on a check engine light 2001 Hyundai with out using computer?

To extract the diagnose code on a check engine light 2001 Hyundai without using a computer, you can perform a self-diagnostic test using the instrument cluster. Here's how to do it:

1. Turn the ignition switch to the "ON" position without starting the engine.

2. Press and hold the "Trip" or "Odometer" button on the instrument cluster for at least 3 seconds until you see the diagnostic trouble codes (DTCs) appear on the display.

3. The DTCs will be displayed as a series of 4-digit codes. Each code represents a specific diagnostic trouble area.

4. If multiple codes are displayed, write down each code and research them separately to determine their meaning and severity.

5. Once you have identified the DTCs, you can use a repair manual or online resources to find the possible causes and solutions for each code.

It's important to note that this method may not retrieve all DTCs and is less comprehensive compared to using a diagnostic scanner. If you're unable to identify or resolve the issue using this method, it's recommended to have the vehicle diagnosed by a qualified mechanic or automotive technician.
