PROCEDURE

1.

CHECK DTC

(a) Clear the DTCs.

Body Electrical > Navigation System > Clear DTCs

(b) Recheck for DTCs and check that no DTCs are output.

  • Remote touch screen touch detection is performed using the electrostatic sensor and G sensor. However, there is no effect on the basic functions of the remote touch screen when the G sensor is not operating. Therefore, a counter is used to prevent DTCs from being output immediately (in order to reduce excessive DTC output). Therefore, when DTCs are not output, it is necessary to turn the engine switch from on (ACC) to off and check for DTCs again.
