How do you reset the trouble codes on 2001 Neon?

To reset the trouble codes on a 2001 Dodge Neon, you can disconnect the negative battery terminal for about 15 minutes, which will clear the engine control module (ECM) memory. After reconnecting the terminal, the check engine light should turn off. Alternatively, you can use an OBD-II scanner to clear the codes directly if you have one available. Ensure to address any underlying issues before resetting, as the check engine light may return if problems persist.
