DESCRIPTION

WIRING DIAGRAM

INSPECTION PROCEDURE

READ VALUE USING GTS (ODO/TRIP CHANGE SW)

INSPECT TRIP SWITCH

CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - TRIP SWITCH)

DESCRIPTION

HINT:

The whole light control rheostat should be replaced if the ODO/TRIP switch is malfunctioning.

WIRING DIAGRAM

INSPECTION PROCEDURE

1. Using the GTS, read the Data List (LandCruiser RM0000012G70JTX.html).
   
   

   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 GTS changes with the actual ODO/TRIP change switch operation.
   

1. Disconnect the G16 trip switch connector.
   

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

1. Disconnect the G6 combination meter assembly connector.
   

2. Disconnect the G16 trip switch connector.
   

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

   Standard Resistance:

   for LHD

   Tester Connection	Condition	Specified Condition
   G6-11 (RSET) - G16-4 (A/B)	Always	Below 1 Ω
   G6-11 (RSET) - Body ground	Always	10 kΩ or higher

   for RHD

   Tester Connection	Condition	Specified Condition
   G6-11 (RSET) - G16-1 (A/B)	Always	Below 1 Ω
   G6-11 (RSET) - Body ground	Always	10 kΩ or higher
