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 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. Warm up the engine.

      2. Connect the GTS to the DLC3.

      3. Turn the engine switch on (IG).

      4. Turn the GTS on.

      5. Enter the following menus: Chassis / ABS/VSC/TRAC / Data List.

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