To reset the check engine light on a 1996 GMC truck, you can disconnect the battery by removing the negative terminal for about 15 minutes. This will clear the vehicle's computer memory and reset the light. Alternatively, you can use an OBD-II scanner to erase the trouble codes, which will also turn off the check engine light.
