   INSPECT COMBINATION METER ASSEMBLY

   
   

   1. Check speedometer operation.

      Note:
      

      • The combination meter assembly receives the vehicle speed signal from the skid control ECU via CAN communication. Therefore, perform the following inspection referring to values on the Data List of the skid control ECU because it is the source of the vehicle speed signal.

      • The Data List values of the skid control ECU are used for this inspection. Therefore, make sure to perform this inspection after confirming that no DTCs are output from the brake control system.

      • If the tire size or tire inflation pressure is not within the specified range, or the tires are excessively worn, the speedometer indication error will increase. Therefore, make sure to perform this inspection after checking that the tire size, tire inflation pressure and tire wear are in the specified range.

      
      

      1. Before starting the following inspection, check if brake control system DTCs are output.

      2. Read the Data List according to the display on the GTS.

         Table 1. ABS/VSC/TRC

         Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
         Vehicle Speed	Maximum wheel speed sensor reading/Min.: 0 km/h (0 mph), Max.: 326 km/h (202 mph)	Vehicle stopped: 0 km/h (0 mph)	When driving at constant speed: No large fluctuations

   2. Inspect tachometer

      
      

      1. Connect the GTS, and start the engine.

      2. Compare the test results with the tachometer indication.

         GTS Indication (rpm)	Acceptable Range (rpm) Data in ( ) is for Reference
         700	630 to 770
         1000	(900 to 1100)
         2000	(1850 to 2150)
         3000	2800 to 3200
         4000	(3800 to 4200)
         5000	4800 to 5200
         6000	(5750 to 6250)
         7000	6700 to 7300

   3. Check LED illumination (LED check)

      
      

      1. Check the illumination function of the warning or indicator lights listed below when turning the power switch on (IG).

         OK
