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.

PROCEDURE


  1. CHECK ILLUMINATION


    1. Check if the illumination for the radio receiver assembly, steering pad switch assembly, heater control switch or others (hazard switch, transmission control switch, etc.) comes on when the light control switch is turned to the head or tail position.

      Disconnect the 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 tail or head 11 to 14 V

    NG
    OK
  3. INSPECT STEERING PAD SWITCH ASSEMBLY


    1. Disconnect the steering pad switch assembly connector.

    2. Connect a battery positive (+) lead to terminal IL+2 and a negative (-) lead to terminal EAU of the steering pad switch assembly connector.

      *2 Vehicle Side

      Disconnect the steering pad switch assembly and spiral cable sub-assembly connectors.

    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 sub-assembly is an important part of the SRS airbag system. Incorrect removal or installation of the spiral cable sub-assembly may prevent the airbag from deploying. Be sure to read the pages shown in the brackets.
