1. Park your car in a safe location and turn off the engine.
2. Locate the Diagnostic Trouble Codes (DTC) connector, which is usually a black, 16-pin connector found under the dashboard or in the engine bay. Refer to your vehicle's owner's manual for the exact location.
3. Locate a paper clip or a suitable tool to use as a jumper wire.
4. Insert one end of the jumper wire into the "TE1" terminal of the DTC connector and the other end into the "E1" terminal.
5. Turn the ignition switch to the "ON" position without starting the engine. This will power up the diagnostic system.
6. Observe the 'Check Engine' light. It might blink several times, indicating the diagnostic codes. Each series of blinks represents a two-digit code, with a pause in between each series.
7. Note down the diagnostic trouble codes by counting the blinks and using the following format:
- A single blink represents the number "1"
- Two blinks represents the number "2"
- And so on
8. Once you have retrieved all the codes, disconnect the jumper wire from the DTC connector and restart the engine.
9. The "Engine" light should turn off if the codes are cleared successfully.
However, it is important to mention that the 'Check Engine' light usually illuminates in response to a detected issue or malfunction within the vehicle's engine or emission system. If the light turns back on or if it remains on continuously, it is recommended to have your vehicle inspected by a qualified mechanic or automotive technician to identify and address the underlying problem.
