INSPECTION PROCEDURE

Note

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 Precautionary Notice for the Supplemental Restraint System Click here.

PROCEDURE


  1. CHECK ILLUMINATION


    1. Check if the illumination for the radio receiver, steering pad switch, integration control & panel assembly, cigarette lighter or others (seat heater switch, hazard switch, etc.) comes on when the light control switch is turned to the HEAD or TAIL position.

  4. INSPECT SPIRAL CABLE


    1. A0160HPE95

      Disconnect the steering pad switch assembly and spiral cable 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
