Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative terminal of the battery for safety.

2. Inspect Sensors

• Locate the blind spot sensors on both sides of the rear bumper.
• Clean the sensors gently with a soft cloth to remove any dirt or debris that may obstruct their function.
• If any sensors are physically damaged, proceed to replace them.

3. Check Fuse

• Locate the fuse box (typically under the dashboard or in the engine compartment).
• Identify the fuse for the blind spot monitoring system (refer to the owner’s manual for the correct fuse number).
• Remove the fuse and inspect it for continuity. If blown, replace it with a new fuse of the same amperage.

4. Inspect Wiring

• Carefully remove the rear bumper if necessary to access the wiring harness connected to the sensors.
• Visually inspect the wiring for any signs of fraying, corrosion, or disconnection.
• Repair or replace any damaged wiring as needed.

5. Reconnect Battery

• Reconnect the negative terminal of the battery.
• Start the vehicle and check if the blind spot monitoring system is functioning correctly.
