The OBD2 port in your vehicle is essential for diagnostics and accessing crucial car data. If you’re experiencing trouble connecting your Aura Obd2 scanner or any OBD2 device, it can be frustrating. Let’s explore common reasons why your OBD2 port might not be working correctly and how to troubleshoot these issues.
One frequent problem is related to the pins inside the OBD2 port itself. Each of the 16 pins has a specific function, from providing battery voltage to supporting various communication protocols like GMLAN and Class 2 Serial Data. If any of these pins are not making proper contact, your Aura OBD2 scanner won’t be able to establish a connection.
A common issue is “pushed back” pin sockets. Sometimes, the small metal receivers inside the OBD2 port can be pushed backward, deeper into the connector housing. This prevents them from making contact with the pins on your Aura OBD2 scanner plug when you connect it. To check for this, use a flashlight and shine it directly into the OBD2 port, looking parallel to the pin sockets. Compare the depth of each socket; if any appear recessed compared to the others, they might be pushed back.
If you identify a pushed-back socket, carefully reach behind the OBD2 connector. Often, you can gently adjust the wire connected to that pin to reposition the socket forward. Avoid inserting any objects into the socket itself to pull it forward, as this can cause damage. Before reconnecting your Aura OBD2 scanner, also inspect the scanner’s plug for any bent pins. If you find bent pins, straighten them very gently.
When reconnecting your Aura OBD2 scanner after making adjustments, do it slowly and pay attention to any resistance. Your Aura OBD2 scanner and most scanners are designed for auto protocol detection, so they should automatically identify the correct communication protocol if the physical connection is sound. Another area to check is the grounding. Ensure the ground pins in the OBD2 port are properly grounded to the chassis.
If you’ve checked for pushed-back pins and bent scanner pins, and your Aura OBD2 scanner still won’t connect, it might indicate a more complex electrical issue. In such cases, it’s advisable to consult a qualified mechanic to diagnose and repair the underlying problem in your vehicle’s communication network. Remember to never use a multimeter probe directly in the OBD2 socket as it can damage the pin receivers.
