1. Prepare the Vehicle:
- Park your Acura MDX on level ground and turn off the engine.
- Put on any necessary safety gear, such as gloves and safety glasses.
2. Locate the OBD-II Port:
- The OBD-II port is usually located under the dashboard on the driver's side of the vehicle. Consult the vehicle's owner's manual if you have trouble finding it.
3. Connect OBD-II Scanner:
- Connect an OBD-II scanner to the vehicle's OBD-II port.
Make sure the scanner is compatible with your Acura MDX model and year.
4. Access Diagnostic Menu:
- Turn the key to the "ON" position, but do not start the engine.
- The OBD-II scanner should power up and display various diagnostic options.
5. Select "Read Codes":
- Navigate through the scanner's menu until you find the option to "Read Codes" or "View DTCs" (Diagnostic Trouble Codes).
Select this option.
6. Review Codes:
- The scanner will display a list of any active diagnostic trouble codes (DTCs) that are stored in the vehicle's computer.
These codes can provide you with information about the engine problem.
7. Clear Codes:
- Once you have reviewed the codes, select the option to "Clear Codes" or "Erase DTCs."
Confirm the action if prompted.
8. Disconnect Scanner:
- Disconnect the OBD-II scanner from the vehicle's OBD-II port.
9. Start and Test:
- Start the vehicle and let it run for a few minutes.
Drive it around for a short distance to check if the engine check light stays off.
10. Repeat if Light Returns:
- If the engine check light returns after some time, it indicates that the underlying issue has not been resolved. You might need further diagnostics or repairs.
Resetting the engine check light only temporarily clears the stored DTCs. If the root cause of the problem is not addressed, the light may turn on again. If the engine check light persists or if you notice other issues, it's recommended to consult with a qualified mechanic or an Acura dealership for proper diagnosis and repairs.
