Engine light reset on 2000 grane cherokee?

To reset the engine light on a 2000 Grand Cherokee, you can disconnect the negative battery terminal for about 15 minutes. This will clear the onboard computer's memory and reset the check engine light. Alternatively, you can use an OBD-II scanner to clear the trouble codes directly, which will also turn off the light. However, ensure that any underlying issues causing the light to activate are resolved before resetting.
