3. Use a multimeter to test the sensor for continuity; replace if it shows no continuity when closed.
4. If replacement is necessary, remove the faulty sensor and install the new one, ensuring proper alignment.

4. Check Wiring and Connections

Sub-steps:
1. Inspect the wiring harness near the door hinges for fraying or damage.
2. Repair any damaged wires with electrical tape or replace the harness if necessary.
3. Ensure all connectors are secure and free of corrosion. Clean as needed.

5. Reassemble and Test

Sub-steps:
1. Reconnect the battery once all repairs are completed.
2. Test each door by opening and closing to ensure the sensor responds correctly.
3. Check for any dashboard alerts related to the door ajar sensor.
