If you own a Lincoln MKX or a similar Ford vehicle, you may have encountered the dreaded “Vehicle Not In Park” message. This issue can also lead to battery drainage, which can be quite frustrating. Today, I’ll walk you through the process of diagnosing and fixing this problem.
Understanding the Problem
When you see the “Vehicle Not In Park” message, it typically means that a small component, such as a micro switch in the shifter assembly, is not making proper contact. This issue can be intermittent, making it even more frustrating. Here’s a step-by-step guide to help you address this problem.
Step-by-Step Guide to Fixing the Issue
Step 1: Initial Diagnosis
- Symptoms: When you put your vehicle in park, the dashboard still indicates that it is not in park. You might also notice all the lights on the shifter mechanism lighting up and losing the ability to manually shift.
- Temporary Fix: Before fixing the issue permanently, you can temporarily clear the message by pressing the shifter button multiple times. This action helps to work the micro switch down there, but it’s not a long-term solution.
Step 2: Prepare for Repair
- Apply the Parking Brake: Ensure the vehicle is securely parked by applying the parking brake.
- Adjust Seats: Move the seats all the way back and down to give yourself ample working space.
Step 3: Remove Trim and Panels
- Remove Side Trim: Start by pulling off the side trim panels. These panels are typically held in place by clips and should come off with some gentle prying.
- Remove the H-Trim: Next, remove the H-shaped trim piece around the shifter. This piece is also held by clips and can be pried off carefully.
- Pull Carpet Trim: Pull back the carpet trim to access the screws holding the shifter assembly.
Step 4: Access the Shifter Assembly
- Unscrew the Assembly: Using a 7mm socket, remove the screws holding the shifter assembly in place. There are typically four screws, two on each side.
- Disconnect Connectors: Carefully disconnect any electrical connectors attached to the shifter assembly. These connectors are usually held by clips, which need to be gently pried off.
Step 5: Replace the Faulty Micro Switch
- Identify the Switch: The faulty micro switch is located within the shifter assembly. This switch is responsible for detecting whether the vehicle is in park.
- Remove the Old Switch: Using a small trim tool or needle nose pliers, carefully release the tabs holding the old switch in place and pull it out.
- Install the New Switch: Insert the new micro switch into the same position, ensuring it clicks into place securely.
Step 6: Reassemble the Shifter
- Reconnect Electrical Connectors: Attach all previously disconnected connectors back to the shifter assembly.
- Reinstall the Assembly: Secure the shifter assembly back in place by screwing in the four screws using the 7mm socket.
- Replace Trim Pieces: Snap the H-trim and side trim panels back into their original positions. Ensure all clips are securely fastened.
Step 7: Test the Repair
- Start the Vehicle: Turn on the vehicle to check if the “Vehicle Not In Park” message has been resolved.
- Shift Through Gears: Shift through the gears and ensure the vehicle recognizes when it is in park.
- Verify Functionality: Make sure the shifter lights up correctly and manual shifting is functional.
Additional Tips
- Regular Maintenance: Regularly check the shifter assembly and ensure all components are in good condition to avoid future issues.
- Battery Check: Ensure your battery is in good condition, as persistent issues with the micro switch can lead to battery drainage.
- Professional Help: If the problem persists, consider consulting a professional mechanic for a thorough inspection.
