BLIND SPOT MONITORING (BSM) CONTROL MODULE INSPECTION

1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].)

2. Remove the rear combination light. (See REAR COMBINATION LIGHT REMOVAL/INSTALLATION.)

3. Remove the rear bumper. (See REAR BUMPER REMOVAL/INSTALLATION.)

4. Connect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].)

5. Verify that the voltages of each of the terminals are as indicated in the terminal voltage table (reference).

• If the voltage is not as specified in the terminal voltage table (reference), inspect the parts under Inspection item(s) and related wiring harnesses.

― If the system does not operate normally even though the inspection items are normal, replace the BSM control module. (See 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.
