    2. Check the resistance.


      1. B000RUYC01
        *1 HUD Switch
        *a

        Component without harness connected

        (Headup Display Switch (No. 3 Combination Switch Assembly))

        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 not pressed 10 kΩ or higher
        5 (ILU) - 15 (CH) HUD switch pressed Below 1 Ω

        If the result is not as specified, replace the headup display switch (No. 3 combination switch assembly).

    3. Check illumination.


      1. B000RUYC02
        *a

        Component without harness connected

        (Headup Display Switch (No. 3 Combination Switch Assembly))

        Apply auxiliary battery voltage to the headup display switch and check that it illuminates.

        OK
        Measurement Condition Specified Condition

        Auxiliary battery positive (+) → Terminal 7 (ILL+)

        Auxiliary battery negative → Terminal 12 (ILL-)

        		 Illuminates

        If the result is not as specified, replace the headup display switch (No. 3 combination switch assembly).

    4. Install the headup display switch (No. 3 combination switch assembly).

      1. B000PAAC03
        *1 HUD Switch
        *a

        Component without harness connected

        (Headup Display Switch (No. 3 Combination Switch Assembly))

        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 not pressed 10 kΩ or higher
        4 (ILU) - 14 (CH) HUD switch pressed Below 1 Ω

        If the result is not as specified, replace the headup display switch (No. 3 combination switch assembly).

    3. Check illumination.


      1. B000PAAC04
        *a

        Component without harness connected

        (Headup Display Switch (No. 3 Combination Switch Assembly))

        Apply auxiliary battery voltage to the headup display switch and check that it illuminates.

        OK
        Measurement Condition Specified Condition

        Auxiliary battery positive (+) → Terminal 7 (ILL+)

        Auxiliary battery negative → Terminal 12 (ILL-)

        		 Illuminates

        If the result is not as specified, replace the headup display switch (No. 3 combination switch assembly).

    4. Install the headup display switch (No. 3 combination switch assembly).
