5.INSPECT SPIRAL CABLE SUB-ASSEMBLY


    Toyota Rav4. Aca30, 33, 38 Gsa33 Zsa30, 35.Audio Visual.Audio And Visual System.Audio And Visual System Illumination Circuit

  1. Remove the spiral cable (RAV4_ACA30 RM000001DNS00EX.html).

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

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    4 (EAU) - 8 (EAU)
    		Spiral cable is turned 2.5 rotations counterclockwise
    		Below 1 Ω
    Spiral cable is centered
    Spiral cable is turned 2.5 rotations clockwise
    12 (IL+2) - 5 (IL+2)
    		Spiral cable is turned 2.5 rotations counterclockwise
    		Below 1 Ω
    Spiral cable is centered
    Spiral cable is turned 2.5 rotations clockwise
    NOTICE:
    The spiral cable is an important part of the SRS airbag system. Incorrect removal or installation of the spiral cable may prevent the airbag from deploying. Be sure to read the Precaution for the SRS (RAV4_ACA30 RM000000KT106QX.html).
