Blind Spot Monitoring (BSM) is a safety feature designed to alert drivers of vehicles in their blind spots. If you are experiencing issues with the BSM on a Toyota Camry XV70, follow this structured approach to diagnose and potentially fix the problem.

Repair Instructions

Cleaning Sensors:

- Ensure they are free from obstructions.
Repairing Wiring:
- If any wiring is found damaged, use electrical tape or heat shrink tubing to repair.
- If severe, splice in new wiring as necessary.
Replacing Sensors:
- If the sensor is defective, replace it with an OEM part.
- Disconnect the old sensor and connect the new one.
- Reassemble any removed components and reconnect the battery.
Resetting the System:
- After repairs, use the OBD-II scanner to clear any DTCs.
- Perform a system reset if necessary, following the procedure in the service manual.
Testing the System:
- Conduct a test drive in a safe area to verify the BSM system operates correctly.
- Ensure the indicator lights function as expected when another vehicle enters the blind spot.
