Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative terminal of the battery to avoid electrical shorts.

2. Inspect and Test Door Latch Sensors

Remove the door panel:
- Use a socket set to remove screws and clips securing the panel.
- Carefully pry the panel away from the door frame without damaging clips.
Access the door latch assembly:
- Locate the latch and sensor assembly inside the door.
Test the sensor:
- Disconnect the connector from the sensor.
- Use a multimeter to check for continuity when the door is closed.
- If there is no continuity, the sensor may need replacement.

3. Replace Faulty Door Latch Sensor

Remove the old sensor:
- Unscrew and detach the sensor from the latch assembly.
Install the new sensor:
- Position the new sensor in the same location and secure it with screws.
Reconnect the wiring harness to the new sensor.
