1. Turn off the engine and open the hood.
2. Locate the negative battery terminal (usually marked with a "-" sign).
3. Use a wrench to loosen the nut or bolt that secures the negative battery cable.
4. Disconnect the cable from the terminal and move it aside.
Wait a few minutes:
5. This will allow the vehicle's electrical system to discharge.
6. After a few minutes, reattach the negative battery cable to the terminal.
7. Tighten the nut or bolt until it is snug.
Start the engine:
8. Start the engine and let it run for a few minutes.
9. The check engine light should now be reset.
10. If the light is still on, you may need to take your vehicle to a mechanic for further diagnosis and repair.
Note:
- Disconnecting the battery may erase some of your vehicle's settings, such as radio presets, so you may need to reprogram them after you reconnect the battery.
- Resetting the check engine light does not fix the underlying problem that caused it to come on. If the light comes back on after you reset it, you should have your vehicle diagnosed by a qualified mechanic.
