Solution

1. Preparation

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

2. Inspect and Clean Seatbelt Buckle

Remove the seatbelt assembly if necessary for better access.
- Tools Needed: Socket set, screwdrivers.
Clean the seatbelt buckle and connector using contact cleaner to remove any debris or corrosion.
Inspect the seatbelt latch for proper engagement and function.

3. Test and Replace Seatbelt Sensor

Using a multimeter, measure the resistance across the seatbelt buckle connector:
- Expected resistance: Typically between 1-10 ohms when buckled.
If the resistance is out of range, proceed to replace the seatbelt sensor.
- Disconnect the seatbelt buckle connector.
- Remove the seatbelt assembly from the vehicle.
- Install the new seatbelt buckle assembly.
- Tools Needed: Socket set, torque wrench.

4. Reconnect and Test

Reconnect the negative battery terminal.
Start the vehicle and observe the seatbelt light.
If the light remains on, check for any error codes and troubleshoot further if necessary.
