      *a HUD Switch
      *b

      Component without harness connected

      (Combination Switch Assembly (Headup Display Switch))

      Check the resistance.

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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      5 (ILU) - 15 (CH) HUD switch on (Pushed) Below 1 Ω
      HUD switch off (Not pushed) 10 kΩ or higher

      If the result is not as specified, replace the combination switch assembly (headup display switch).

      *a Illuminates
      *b

      Component without harness connected

      (Combination Switch Assembly (Headup Display Switch))

      Check the illumination.

      Apply battery voltage to the connector and check the illumination condition.

      OK
      Measurement Condition Specified Condition

      Battery positive (+) → Terminal 7 (ILL+)

      Battery negative (-) → Terminal 12 (ILL-)

      		 Illuminates

      If the result is not as specified, replace the combination switch assembly (headup display switch).

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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      4 (ILU) - 14 (CH) HUD switch on (Pushed) Below 1 Ω
      HUD switch off (Not pushed) 10 kΩ or higher

      If the result is not as specified, replace the combination switch assembly (headup display switch).
