METER / GAUGE SYSTEM ON-VEHICLE INSPECTION


  1. INSPECT COMBINATION METER ASSEMBLY


    1. INSPECT SPEEDOMETER

      Note


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

      • Data List values of the brake actuator assembly (skid control ECU) 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 the vehicle stability control system outputs the DTCs.

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

    2. INSPECT TACHOMETER


      1. Connect the GTS, and start the engine.

      2. Compare the test results with the tachometer indications.
