Facing a Check Engine Light on your 2012 Dodge Journey can be unsettling, especially when you’re trying to diagnose the issue yourself. Like many Dodge Journey owners, you might reach for an OBDII scanner to understand what’s going on under the hood. You’re not alone if you’ve encountered difficulties connecting your scanner and getting the diagnostic information you need. Let’s explore how to properly connect your OBDII scanner to your 2012 Dodge Journey and troubleshoot common problems.
It sounds like you’re experiencing frustration similar to others when trying to use an OBDII scanner, like your Actron CP9575, with your Dodge Journey. You’re right to assume that as an OBDII compliant vehicle, your 2012 Dodge Journey should be compatible with an OBDII scanner. The standard OBDII protocol is designed to provide universal access to vehicle diagnostic data. However, the connection process and potential glitches can sometimes be confusing.
Let’s address the common hurdles and ensure you can effectively use your OBDII scanner on your 2012 Dodge Journey. Here’s a step-by-step approach and some troubleshooting tips:
First, confirm the basic connection procedure. Typically, you should:
- Locate the OBDII port in your 2012 Dodge Journey. It’s usually found under the dashboard on the driver’s side.
- Ensure your Dodge Journey’s ignition is in the “Run” position. This means turning the key to the position just before starting the engine – where the dashboard lights and electrical systems are active. Do not start the engine.
- Plug your Actron CP9575 OBDII scanner into the port.
- Turn on your scanner. It should power up and attempt to establish a connection with your vehicle’s computer.
- Follow your scanner’s instructions to initiate a vehicle scan.
You mentioned that when you try to put your car in “Run” mode with the scanner connected, it doesn’t seem to engage properly, and when you connect the scanner after putting the car in “Run” mode, things go haywire with wipers and dashboard lights. This suggests a potential communication issue or possibly a glitch.
Here are a few things to consider and try:
- Scanner Compatibility: While the Actron CP9575 is an OBDII scanner and should be compatible, double-check its compatibility list or manufacturer’s website to confirm it’s officially supported for 2012 Dodge Journey models. Although OBDII is a standard, some older or very basic scanners might have limitations with certain vehicle makes or models.
- Connection Sequence: Try connecting the scanner before turning the ignition to the “Run” position. Some scanners prefer to be connected before the vehicle’s systems fully power up.
- Firm Connection: Ensure the scanner is firmly plugged into the OBDII port. A loose connection can cause intermittent communication or no connection at all.
- Scanner Software Update: You mentioned you updated your scanner, which is excellent. Ensure the update process was successful and that you have the latest software version for your Actron CP9575. Sometimes updates resolve compatibility issues.
- Vehicle Battery Voltage: Low battery voltage in your Dodge Journey can sometimes interfere with electronic systems and scanner communication. Ensure your battery is in good condition and fully charged.
- Check for Port Damage: Inspect the OBDII port in your Dodge Journey for any signs of damage or corrosion. A damaged port can prevent proper connection.
If you’ve tried these steps and are still facing issues, it might be helpful to:
- Try a Different Scanner: If possible, borrow or try a different OBDII scanner to see if it connects to your 2012 Dodge Journey. This will help determine if the issue is with your Actron CP9575 scanner itself or with your vehicle’s system.
- Consult Your Dodge Journey Owner’s Manual: While it might not have specific scanner instructions, your owner’s manual may have information about the OBDII system or any specific procedures for diagnostics.
- Seek Professional Assistance: If you continue to struggle, consider taking your 2012 Dodge Journey to a trusted mechanic or auto repair shop. They have professional-grade scan tools and expertise to diagnose the Check Engine Light and any potential communication issues with the OBDII system.
Diagnosing your Check Engine Light with an OBDII scanner on your 2012 Dodge Journey should be a straightforward process. By following these steps and troubleshooting tips, you should be able to connect your scanner and get the diagnostic information you need to address your vehicle’s issue.
