CAUTION / NOTICE / HINT

NOTICE:

Inspect the fuses for circuits related to this system before performing the following procedure.

PROCEDURE

1.	CHECK HARNESS AND CONNECTOR (BLIND SPOT MONITOR SENSOR LH (MASTER) POWER SOURCE)

*a	Front view of wire harness connector (to blind spot monitor sensor LH (Master))

(a) Disconnect the blind spot monitor sensor LH (Master) connector.

(b) Measure the voltage according to the value(s) in the table below.

Standard Voltage:

Tester Connection	Switch Condition	Specified Condition
M62-5 (BLB) - Body ground	Ignition switch to ON	11 to 14 V
M62-5 (BLB) - Body ground	Ignition switch off	Below 1 V

REPAIR OR REPLACE HARNESS OR CONNECTOR

2.	CHECK HARNESS AND CONNECTOR (BLIND SPOT MONITOR SENSOR LH (MASTER) - BODY GROUND)

(a) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
M62-10 (BLGD) - Body ground	Always	Below 1 Ω

REPAIR OR REPLACE HARNESS OR CONNECTOR

3.	CHECK HARNESS AND CONNECTOR (BLIND SPOT MONITOR SENSOR RH (SLAVE) POWER SOURCE)

*a	Front view of wire harness connector (to blind spot monitor sensor RH(Slave))

(a) Disconnect the blind spot monitor sensor RH (Slave) connector.

(b) Measure the voltage according to the value(s) in the table below.

Standard Voltage:

Tester Connection	Switch Condition	Specified Condition
M63-5 (BRB) - Body ground	Ignition switch to ON	11 to 14 V
M63-5 (BRB) - Body ground	Ignition switch off	Below 1 V

REPAIR OR REPLACE HARNESS OR CONNECTOR

4.	CHECK HARNESS AND CONNECTOR (BLIND SPOT MONITOR SENSOR RH (SLAVE) - BODY GROUND)

(a) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
M63-10 (BRGD) - Body ground	Always	Below 1 Ω
