   READ VALUE USING INTELLIGENT TESTER (ODO/TRIP CHANGE SW)

   
   

   1. Connect the intelligent tester to the DLC3.

   2. Turn the power switch on (IG).

   3. Turn the tester on.

   4. Enter the following menus: Body Electrical / Combination Meter / Data List.

   5. Check the values by referring to the table below.

      Table 1. Combination Meter

      Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
      ODO/TRIP Change SW	ODO/TRIP change switch/OFF or ON	OFF: ODO/TRIP change switch released	-
      		ON: ODO/TRIP change switch pressed

      OK
      The value displayed on the intelligent tester changes with the actual ODO/TRIP change switch operation.

   INSPECT LIGHT CONTROL RHEOSTAT

   
   

   1. for RHD

      
      
      1. 

         Remove the light control rheostat.

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

         Standard Resistance
         Tester Connection Switch Condition Specified Condition 2 (A/B) - 5 (E) ODO/TRIP change switch pressed Below 1 Ω 2 (A/B) - 5 (E) ODO/TRIP change switch not pressed 10 kΩ or higher

         Table 2. Text in Illustration

         *1	Component without harness connected (Light Control Rheostat)

   2. for LHD

      
      
      1. 

         Remove the light control rheostat.

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

         Standard Resistance
         Tester Connection Switch Condition Specified Condition 2 (A/B) - 5 (E) ODO/TRIP change switch pressed Below 1 Ω 2 (A/B) - 5 (E) ODO/TRIP change switch not pressed 10 kΩ or higher

   CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - LIGHT CONTROL RHEOSTAT)

   
   
   1. 

      Disconnect the F16 connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition F16-9 (A/B) - F6-2 (A/B) Always Below 1 Ω F16-9 (A/B) - Body ground Always 10 kΩ or higher
