Common Causes and Troubleshooting Steps for a Dead OBD2 Port

Several factors can contribute to a powerless OBD2 port in a Dodge Challenger. Understanding these potential issues will help you diagnose and fix the problem effectively.

• Blown Fuse: The most frequent cause. Locate the OBD2 port fuse (consult your owner’s manual) and check for a break in the wire. Replace the fuse if necessary.

• Faulty OBD2 Port: In rare cases, the OBD2 port itself might be defective. Try a different OBD2 scanner or consult a professional for testing and replacement if needed.
• Data Link Connector (DLC) Problems: The DLC is the actual connector within the OBD2 port. Check for bent or broken pins inside the DLC. A damaged DLC may require replacement. This can also affect tools like a hellcat exhaust tuner obd2.
