PROCEDURE


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


    1. Disconnect the X2 blind spot monitor sensor LH connector.

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      X2-5 (BLB) - Body ground Engine switch on (IG)

      11 to 14 V*1

      10.5 to 16 V*2
      X2-5 (BLB) - Body ground Engine switch off Below 1 V

      • *1: w/o Stop and Start System

      • *2: w/ Stop and Start System

      Result
      Result Proceed to
      OK A
      NG (w/o Stop and Start System) B
      NG (w/ Stop and Start System) C
