METER / GAUGE SYSTEM ON-VEHICLE INSPECTION

PROCEDURE

1. INSPECT COMBINATION METER ASSEMBLY

   
   

   1. Check speedometer operation

      Note

      
      

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

      • Data List values of the skid control ECU (brake actuator assembly) are used for this inspection. Therefore, make sure to perform this inspection after confirming that DTCs are not output.

      • 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 vehicle stability control system DTCs are output.

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

         
         Chassis > ABS/VSC/TRC > Data List

         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)
