TRIP SWITCH INSPECTION

PROCEDURE


  1. INSPECT TRIP SWITCH (w/o TAIL Cancel Switch)


    1. Inspect the light control rheostat.


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

        A01XFA0E01
        Standard Resistance
        for LHD
        Tester Connection Switch Condition Specified Condition
        5 (T) - 1 (E) Always 8 to 12 kΩ
        7 (RV) - 1 (E) Light control rheostat fully turned right → Light control rheostat fully turned left Below 100 Ω → 8 to 12 kΩ
        for RHD
        Tester Connection Switch Condition Specified Condition
        8 (T) - 4 (E) Always 8 to 12 kΩ
        6 (RV) - 4 (E) Light control rheostat fully turned right → Light control rheostat fully turned left Below 100 Ω → 8 to 12 kΩ

    2. Inspect the ODO/TRIP switch.


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

        Standard Resistance
        for LHD
        Tester Connection Switch Condition Specified Condition
        4 (A/B) - 1 (E) ODO/TRIP switch on (Pushed) Below 1 Ω
        ODO/TRIP switch off (Not pushed) 1 MΩ or higher
        for RHD
        Tester Connection Switch Condition Specified Condition
        1 (A/B) - 4 (E) ODO/TRIP switch on (Pushed) Below 1 Ω
        ODO/TRIP switch off (Not pushed) 1 MΩ or higher

        If the result is not as specified, replace the rheostat.

  2. INSPECT TRIP SWITCH (w/ TAIL Cancel Switch)


    1. Inspect the light control rheostat.


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

        A01XLY7E01
        Standard Resistance
        for LHD
        Tester Connection Switch Condition Specified Condition
        5 (T) - 6 (TC) TAIL cancel switch off → on 1 MΩ or higher → Below 100 Ω
        5 (T) - 1 (E) Always 8 to 12 kΩ
        7 (RV) - 1 (E) Light control rheostat fully turned right → Light control rheostat fully turned left Below 100 Ω → 8 to 12 kΩ
        for RHD
        Tester Connection Switch Condition Specified Condition
        7 (TC) - 8 (T) TAIL cancel switch off → on 1 MΩ or higher → Below 1 Ω
        8 (T) - 4 (E) Always 8 to 12 kΩ
        6 (RV) - 4 (E) Light control rheostat fully turned right → Light control rheostat fully turned left Below 100 Ω → 8 to 12 kΩ

    2. Inspect the ODO/TRIP switch.


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

        Standard Resistance
        for LHD
        Tester Connection Switch Condition Specified Condition
        4 (A/B) - 1 (E) ODO/TRIP switch on (Pushed) Below 1 Ω
        ODO/TRIP switch off (Not pushed) 1 MΩ or higher
        for RHD
        Tester Connection Switch Condition Specified Condition
        1 (A/B) - 4 (E) ODO/TRIP switch on (Pushed) Below 1 Ω
        ODO/TRIP switch off (Not pushed) 1 MΩ or higher

        If the result is not as specified, replace the rheostat.
