INSPECTION PROCEDURE

CAUTION:

The vehicle is equipped with an SRS (Supplemental Restraint System) which includes components such as airbags. Before servicing (including removal or installation of parts), be sure to read the Precaution in the Supplemental Restraint System Click here.

PROCEDURE


  1. CHECK ILLUMINATION


    1. Check if the illumination for the navigation receiver assembly, steering pad switch, glove box or other parts (hazard switch, transmission control switch, etc.) comes on when the light control switch is turned to the HEAD or TAIL position.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      8 (EAU) - 4 (EAU) Centered Below 1 Ω
      Rotated 2.5 times to the left
      Rotated 2.5 times to the right
