INSPECTION PROCEDURE

Note

The vehicle is equipped with an Supplemental Restraint System (SRS). Before servicing (including removal or installation of parts), be sure to read the precaution notice for Supplemental Restraint System Click here.

PROCEDURE


  1. CHECK ILLUMINATION


    1. Check if the illumination for the display and navigation module display, steering pad switch assembly, glove box or others (hazard switch, etc.) comes on when the light control switch is turned to the head or tail position.

  2. CHECK HARNESS AND CONNECTOR (BATTERY - SPIRAL CABLE SUB-ASSEMBLY)


    1. Disconnect the J24 spiral cable sub-assembly connector.

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      J24-12 (IL+2) - Body ground Light control switch in tail or head 11 to 14 V

      *3 Vehicle Side

      Disconnect the k1 steering pad switch assembly connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      k1-8 (EAU) - J24-4 (EAU) Center Below 1 Ω
      2.5 rotations to the left
      2.5 rotations to the right
      k1-5 (IL+2) - J24-12 (IL+2) Center Below 1 Ω
      2.5 rotations to the left
      2.5 rotations to the right

      Note

      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. Refer to the pages shown in the brackets.
