As the owner of Kevin's Autos, I've seen my fair share of Dodge Darts come through the shop over the years. One common issue that can arise is the need to reset the car's computer, also known as the Powertrain Control Module (PCM). This process is important for troubleshooting various problems, from engine performance issues to check engine lights. In this article, I'll walk you through the steps to reset the computer on your Dodge Dart.
Why Reset the Computer?
Resetting the computer on your Dodge Dart can be beneficial in a few key situations:
- Clearing Diagnostic Trouble Codes: If your Dodge Dart's check engine light is illuminated, the PCM has stored one or more diagnostic trouble codes. Resetting the computer will clear these codes, allowing you to diagnose the underlying issue.
- Resolving Performance Issues: Sometimes, the computer can become overwhelmed or confused, leading to problems like poor fuel economy, rough idling, or misfiring. Resetting the PCM can help reset the computer's parameters and restore proper engine performance.
- After Replacing Components: If you've replaced parts like the battery, alternator, or engine control module, resetting the computer is often necessary to allow the new components to sync up properly with the PCM.
Steps to Reset the Computer
Resetting the computer on a Dodge Dart is a straightforward process that you can do at home. Here's what you'll need to do:
- Locate the Negative Battery Terminal: This is usually a black cable connected to the negative (-) terminal on your Dodge Dart's battery.

- Wait 30 Minutes: This allows the computer to fully discharge and reset.li>
