2005 Lincoln Town Car Service Engine Light Reset

If the service engine light is on in your 2005 Lincoln Town Car, it means that the engine control module (ECM) has detected a problem with the engine. The ECM will store a code in its memory that indicates the problem. You can retrieve the code by using a code reader or by taking the car to a mechanic. Once you have the code, you can use it to diagnose the problem and repair it.

Once you have repaired the problem, you can reset the service engine light by following these steps:

1. Turn the ignition key to the “off” position.
2. Disconnect the negative battery terminal.
3. Wait 10 minutes.
4. Reconnect the negative battery terminal.
5. Turn the ignition key to the “on” position, but do not start the engine.
6. Press the gas pedal all the way down and hold it for 10 seconds.
7. Release the gas pedal and start the engine.

The service engine light should now be reset.
