INSPECTION PROCEDURE

NOTICE:
  1. When checking for DTCs, make sure that the blind spot monitor main switch (steering pad switch assembly [multi-function switch]) is on.
  2. Inspect the fuses for circuits related to this system before performing the following inspection procedure.
1.CHECK HARNESS AND CONNECTOR (BLIND SPOT MONITOR SENSOR RH - BLIND SPOT MONITOR SENSOR LH)

  1. Disconnect the r1 blind spot monitor sensor RH connector.

  1. Disconnect the r2 blind spot monitor sensor LH connector.

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

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    r1-6 (CA2P) - r2-1 (CA2P)
    		Always
    		Below 1 Ω
    r1-1 (CA2N) - r2-8 (CA2N)
    		Always
    		Below 1 Ω
