how to fix the door locks not working on my Honda CR-V Sixth Generation (2023-present)

Solution

1. Preparation

• Gather tools: OBD-II scanner, multimeter, screwdriver set, trim removal tools, and replacement parts if necessary.
• Ensure the vehicle is parked securely and the ignition is off.

2. Check Key Fob and Battery

• Sub-step 1: Replace the battery in the key fob. Use a small screwdriver to open the fob casing.
• Sub-step 2: Test the new battery by attempting to lock/unlock the doors.

3. Inspect Wiring and Connectors

• Sub-step 1: Remove the interior door panel using trim removal tools to access the wiring harness.
• Sub-step 2: Visually inspect the wiring for frays, corrosion, or disconnections.
• Sub-step 3: Use a multimeter to check for continuity in the wiring. Repair or replace any damaged wires.

4. Test and Replace Door Lock Actuator

• Sub-step 1: Locate the door lock actuator within the door assembly after removing the door panel.
• Sub-step 2: Disconnect the actuator and test it with a multimeter for proper voltage when attempting to lock/unlock.
• Sub-step 3: If the actuator is faulty, remove it by unscrewing any mounting screws and disconnecting it from the wiring harness.
• Sub-step 4: Install the new door lock actuator by reversing the removal steps.

5. Check and Replace Fuse
