        • Indicator or warning light or indicator light comes on when turning the power switch from off to on (READY) for 3 seconds, then goes off.

        • *1: w/ Multi-information display

        • *2: w/o Multi-information display

        • *3: w/ LED headlights

        • *4: w/ Automatic headlight beam level control

        • *5: w/ Pre-crash safety system

        • *6: w/ Tire pressure warning system

    2. INSPECT SPEEDOMETER

      Note


      • The combination meter sub-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 the 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 the 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 brake control system outputs the DTCs.

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

      Tech Tips

      When the headup display position or illuminance has not adjusted properly, headup display may not be seen in the front glass. Before starting the following inspection, confirm the headup display position and illuminance.


      1. Turn the power switch off.

      2. Turn the power switch on (IG) while pressing and holding the headup display main switch.

      3. Keep pressing the headup display main switch and turn the power switch off.

      4. Keep pressing the headup display main switch and turn the power switch on (IG).

      5. The headup display will show "TEST MODE".

      6. Inspect the headup display as shown in the illustration.

      7. Turn the power switch off to finish test mode.
