LIGHT CONTROL RHEOSTAT INSPECTION

Tech Tips


  • Use the same procedure for RHD and LHD vehicles.

  • The procedure listed below is for LHD vehicles.


  1. INSPECT TRIP SWITCH (LIGHT CONTROL RHEOSTAT)

    Component without harness connected

    {Trip Switch (Light Control Rheostat)}

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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      3 (IG) - 5 (E)

      Up switch on

      (Pushed)

      		 Below 1 Ω
      3 (IG) - 5 (E)

      Up switch off

      (Not pushed)

      		 10 kΩ or higher
      3 (IG) - 5 (E)

      Down switch on

      (Pushed)

      		 1.7 to 1.8 kΩ
      3 (IG) - 5 (E)

      Down switch off

      (Not pushed)

      		 10 kΩ or higher

      If the result is not as specified, replace the trip switch (light control rheostat).

      {Trip Switch (Light Control Rheostat)}

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

      OK
      Measurement Condition Specified Condition

      Battery positive (+) → Terminal 8 (ILL+)

      Battery negative (-) → Terminal 6 (ILL-)

      		 Illuminates

      If the result is not as specified, replace the trip switch (light control rheostat).
