Blind Spot Monitoring (BSM) Control Module Removal/Installation

CAUTION:

Configuration cannot be implemented correctly if only the blind spot monitoring (BSM) control module (RH) is replaced. When replacing the blind spot monitoring (BSM) control module (RH), it is necessary to replace the blind spot monitoring (BSM) control module (LH) at the same time.

Remove the following parts:
1. Rear combination light (See REAR COMBINATION LIGHT REMOVAL/INSTALLATION .)
2. Rear splash shield (See SPLASH SHIELD REMOVAL/INSTALLATION .)

Perform the BSM radar test. (See BLIND SPOT MONITORING (BSM) RADAR TEST .)
