Need to reset the check engine light on a 1989 Dodge Dakota tried unhooking battery any help out there?

To reset the check engine light on a 1989 Dodge Dakota without disconnecting the battery, you can perform a key-on/key-off reset. Here's how to do it:

1. Turn the ignition key to the "ON" position, but do not start the engine.

2. Wait at least 10 seconds in the "ON" position.

3. Turn the ignition key to the "OFF" position.

4. Wait at least 5 seconds in the "OFF" position.

5. Repeat steps 1 to 4 three times in total.

6. Start the engine and let it idle for a few minutes.

7. Check if the check engine light has turned off.

If the check engine light remains on after performing the key-on/key-off reset, it may be necessary to use a scan tool to read and clear the trouble codes that caused the light to illuminate.
