Blind Spot Module: Testing and Inspection




BLIND SPOT MONITORING (BSM) CONTROL MODULE INSPECTION

1. Remove the trunk box.

2. Remove the seat side box. (BSM control module (LH) only) Seat Side Box Removal/Installation

3. Remove the trunk end trim. (BSM control module (LH) only) (Vehicles with Bose(R)) Trunk End Trim Removal/Installation

4. Remove the bass-box. (BSM control module (LH) only) (Vehicles with Bose(R)) Bass-Box Removal/Installation

5. Remove the BSM control module with the connector connected.

6. Measure the BSM control module terminal voltage using the short wiring harness connector in the position shown in the figure.






NOTE:
- The BSM control module connector cannot be connected to a tester due to its water-resistance processing, therefore the short wiring harness connector is used for measuring the terminal voltage.

- If the terminal voltage is not as indicated in the table, inspect the short wiring harness connector for continuity. If the short wiring harness connector is normal, inspect the parts under "Inspection items".

- If the system does not work properly even though the parts or related wiring harnesses do not have any malfunction, replace the BSM control module.
