Fixing the Trunk Release Issue in a 2019 Toyota Camry XV70

Repair Instructions

Step 1: Replacing the Key Fob Battery

Use a small flathead screwdriver to gently pry open the key fob.
Replace the old battery with a new CR2032 battery, ensuring the positive (+) side is facing up.
Snap the fob back together and test the trunk release.

Step 2: Inspecting the Trunk Release Button

Remove the panel covering the interior trunk release button (if necessary).
Use a multimeter to check for continuity when the button is pressed. If there is no continuity, replace the button.
Reassemble the panel.

Step 3: Inspecting and Testing the Trunk Latch

Open the trunk manually if possible.
Inspect the latch mechanism for any obstructions or dirt; clean it if necessary.
Manually operate the latch with a screwdriver to ensure it moves freely.

Step 4: Checking and Replacing the Fuse

Locate the fuse box (usually found under the dashboard or in the engine compartment).
Identify the fuse for the trunk release (refer to the owner's manual).
Remove the fuse and visually inspect it. If the filament is broken, replace it with a new fuse of the same amperage.
Reinstall the fuse and test the trunk release again.

Step 5: Inspecting Wiring and Connections

Follow the wiring harness from the trunk release button to the latch, looking for signs of wear or damage.
Repair any damaged wires using electrical tape or connectors.
Ensure all connectors are securely fastened.

Step 6: Using an OBD-II Scanner

Plug in the OBD-II scanner and turn the ignition to the "ON" position.
Check for any DTCs that may point to electrical issues affecting the trunk release.
Address any codes accordingly, which may involve further electrical diagnosis or repair.

Conclusion

If all the tests and repairs have been conducted and the trunk release still does not function, it may indicate a deeper issue with the vehicle's body control module (BCM). In such a case, consult a professional technician or your local Toyota dealer for advanced diagnostics and repairs.
