Using an Autel check engine light diagnostic unit is a straightforward process. Follow these steps to diagnose your vehicle’s problems:
3.1. Step 1: Connect the Diagnostic Unit
Locate the OBD2 port in your vehicle. It is typically located under the dashboard on the driver’s side. Plug the Autel diagnostic unit into the OBD2 port.
3.2. Step 2: Power On the Diagnostic Unit
Turn the ignition key to the “ON” position, but do not start the engine. The Autel diagnostic unit should power on automatically.
3.3. Step 3: Select Vehicle Information
Enter your vehicle’s make, model, and year into the diagnostic unit. Some Autel units can automatically detect the vehicle information.
3.4. Step 4: Read Diagnostic Trouble Codes (DTCs)
Select the “Read Codes” or “Diagnostic” option in the menu. The Autel unit will scan your vehicle’s computer and display any stored DTCs.
3.5. Step 5: Interpret the DTCs
Use the built-in DTC library or search online to understand the meaning of each code. The DTC definitions will help you identify the potential problems.
Example DTCs and Their Meanings:
| DTC | Description | Possible Causes |
|---|---|---|
| P0171 | System Too Lean (Bank 1) | Vacuum leak, faulty oxygen sensor, dirty fuel injectors, low fuel pressure |

If available, view the freeze frame data associated with the DTCs. This data provides a snapshot of the vehicle’s operating conditions when the fault occurred.
3.7. Step 7: Clear the DTCs (Optional)
After you have identified and repaired the problem, you can clear the DTCs using the “Clear Codes” or “Erase Codes” option. Note that clearing the codes will also reset the vehicle’s monitors, so you may need to drive the vehicle for a while to allow the monitors to complete their tests.
3.8. Step 8: Perform a Test Drive
After clearing the codes, perform a test drive to ensure the problem has been resolved and the check engine light does not reappear.
