INSPECTION PROCEDURE

Note


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

  • Inspect the fuse for circuits related to this system before performing the following inspection procedure.

PROCEDURE


  1. CHECK ILLUMINATION


    1. Check if the illumination for the multi-media module receiver assembly, accessory meter assembly, steering pad switch assembly or others (hazard switch etc.) comes on when the light control switch is turned to the head or tail position.
