Fixing the Trunk Release Button Not Functioning in a 2020 Toyota Camry XV70
Tools Required
  • Multimeter
  • OBD-II Scanner
  • Screwdriver Set (Phillips and Flathead)
  • Trim Removal Tool
  • Replacement Fuse (if needed)
  • Replacement Key Fob Battery (if needed)

Repair Instructions

Step 1: Check the Key Fob Battery

  1. Open the Key Fob:

    • Use a flathead screwdriver to carefully pry open the key fob.

  2. Replace the Battery:

    • Remove the old battery and replace it with a new CR2032 or CR2025 battery, ensuring the polarity is correct.

  3. Test the Key Fob:

    • Try pressing the trunk release button again to see if it functions.
Step 2: Inspect the Trunk Release Fuse

  1. Locate the Fuse Box:

    • The fuse box is typically located under the dashboard on the driver's side or in the engine compartment.

  2. Check the Owner's Manual:

    • Refer to the owner's manual for the specific location of the trunk release fuse.

  3. Inspect the Fuse:

    • Remove the designated fuse using a fuse puller or pliers.
    • Check if the fuse is blown (the metal strip inside is broken).

  4. Replace the Fuse:

    • If blown, replace it with a fuse of the same amperage rating.
Step 3: Test the Trunk Release Button

  1. Access the Interior Button:

    • Use a trim removal tool to carefully remove the panel around the trunk release button.

  2. Inspect Wiring and Connections:

    • Check the wiring for any visible damage or disconnections.
    • Ensure the electrical connector is securely attached.

  3. Test for Voltage:

    • Use a multimeter to check for voltage at the button when pressed.
    • If no voltage is present, further investigate the wiring harness leading to the button.
Step 4: Examine the Trunk Release Mechanism

  1. Remove the Trunk Latch Assembly:

    • Open the trunk and locate the latch mechanism.
    • Remove the screws or bolts securing the latch and disconnect any electrical connectors.

  2. Inspect the Latch:

    • Look for any signs of damage, corrosion, or physical obstruction.
    • Clean any debris and lubricate moving parts as necessary.

  3. Test the Latch Mechanism:

    • Manually operate the latch to ensure it opens and closes smoothly.

  4. Reinstall the Latch:

    • Carefully reattach the latch assembly and secure it with screws/bolts.
Step 5: Scan for Diagnostic Trouble Codes (DTCs)

  1. Connect the OBD-II Scanner:

    • Plug the scanner into the OBD-II port under the dashboard.

  2. Read Codes:

    • Follow the scanner instructions to read any codes related to the body control module.

  3. Address Any Codes:

    • Research and address any trouble codes that may indicate an issue with the trunk release system.

Final Steps

  • Reassemble Any Trim Panels:

    • Once all checks and repairs are complete, reassemble any panels removed during inspection.

  • Test All Functions:

    • Test the trunk release button from the key fob and inside the vehicle to confirm that the issue has been resolved.

If after following all these steps the trunk release button is still not functioning, it may be necessary to contact a professional technician for further diagnosis or to replace the body control module.
