How to Reset Dodge Challenger Computer?

To reset the Dodge Challenger computer and clear any stored codes or issues, you can follow these simple steps:

1. First, ensure that the car is in park, the engine is turned off, and the key is out of the ignition.

2. Locate the negative battery terminal. It is usually black and marked with a minus (-) sign. You may need to use a wrench or a socket to loosen the terminal nut.

3. Once the negative terminal is loosened, remove the cable from the battery entirely. Ensure that it does not come in contact with the terminal while performing the next steps.

5. After the waiting period, reconnect the negative battery terminal by tightening the nut. Ensure it is securely connected.

6. Turn on the ignition without starting the engine. Allow the car to remain in this state for a few minutes to allow the computer to recalibrate itself.

7. Finally, start the engine and let it idle for a few minutes. This will allow the computer to relearn its settings and adapt to any modifications you may have made.
