OK:
No DTCs are output.
HINT:
-
If DTC B155B is output, perform troubleshooting for DTC B155B first.

- Touch pad touch detection is performed using the electrostatic sensor and G sensor. However, there is no effect on the basic functions of the touch pad 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 power switch from on (ACC) to off and check for DTCs again.

| 2. | REMOTE TOUCH SELF CHECK (CHECK TOUCH SCREEN OPERATION POSITION RECOGNITION CONDITION) |
(a) Enter self-diagnostic mode.
Click here
| (b) Operate the remote touch screen diagonally from the upper left to the lower right and check that the brightness of the switch illumination changes. NOTICE: Since the remote touch screen may recognize a pinch in/out operation if operated with 2 fingers, always use 1 finger to operate the remote touch in self-diagnostic mode. OK: Brightness changes according to touch screen operation.
