Regarding Wiring Diagram information, refer to WIRING DIAGRAM .

1. CHECK METER CONTROL SWITCH SIGNAL
   
   
   1. Turn ignition switch ON.
   2. Check voltage between the following terminals of the meter control switch harness connector M3.

      Meter control switch			Condition	Voltage (Approx.)
      Connector	Terminals
      	(+)	(-)
      M3	7	4	When illumination control switch (-) is pressed	0 V
      			Other than the above	5 V
      	5		When trip reset switch is pressed	0 V
      			Other than the above	5 V
      	6		When illumination control switch (+) is pressed	0 V
      			Other than the above	5 V

   Is the inspection result normal?

   YES 

   Inspection End.

   NO 

   GO TO STEP 2. 

2. CHECK METER CONTROL SWITCH HARNESS
   
   
   1. Turn ignition switch OFF.
   2. Disconnect combination meter harness connector M77 and meter control switch harness connector M3.
   3. Check continuity between combination meter harness connector M77 and meter control switch harness connector M3.

      Connector	Terminal	Connector	Terminal
      M77	18	M3	5	Yes
      	37		7
      	36		6
      	17		4

   4. Check continuity between combination meter harness connector and ground.

      Combination meter		Ground	Continuity
      Connector	Terminal
      M77	18		No
      	37
      	36
      	17
