Lexus ES: Operation Check

Lexus ES (XZ10) Service Manual / Audio & Visual & Telematics / Audio / Video / Audio And Visual System (for Gasoline Model) / Operation Check

OPERATION CHECK

REMOTE TOUCH (REMOTE OPERATION CONTROLLER ASSEMBLY) SELF CHECK

NOTICE:

Before entering self-diagnostic mode, make sure there are no obstructions which may interfere with operation of the remote touch screen, and that the remote touch screen is not dirty.
Do not touch the remote touch screen except when necessary.
Since the remote touch screen may recognize a pinch in/out or flick operation if operated with 2 fingers, always use 1 finger to operate the remote touch screen in self-diagnostic mode.

HINT:

The following checks can be done via self-diagnostic mode:

Remote touch (remote operation controller assembly) DTC check
Switch illumination check
Remote touch screen operation position recognition check
Switch operation check
Vibration feedback generation condition check

(a) Activate Self-diagnostic Mode

*a	"HOME" Switch
*b	Back Switch
*c	Sub-function Switch
*d	Remote Touch Screen

(1) Turn the light control switch to the tail or head position.

(2) The "HOME" switch, back switch and sub-function switch pressed, turn the engine switch on (ACC) to enter self-diagnostic mode.

NOTICE:

Self-diagnostic mode will not start if any switches other than "HOME" switch, back switch and sub-function switch are pressed.

(b) Switch Illumination Check and DTC Check

(1) Check that the switch illumination turns on.

*a	Switch Illumination

HINT:

If present DTCs are stored during self-diagnostic mode, the switch illumination will blink at 0.5-second intervals. The switch illumination will continue to blink until self-diagnostic mode is ended.

*a	Lateral Axis
*b	Longitudinal Axis

(1) Operate the remote touch screen laterally and longitudinally and check that the brightness of the switch illumination changes.

HINT:

If the brightness of the switch illumination changes according to the position touched on the remote touch screen, the remote touch screen operation position is correctly being recognized.
The brightness of the switch illumination changes between 0% and 100% according to the remote touch screen operation coordinates.
The remote touch screen operation coordinates change between 0 and 255 on the lateral axis and longitudinal axis.
When the remote touch screen operation coordinates are 0 for the lateral axis and 0 for the longitudinal axis, the brightness of the switch illumination will be 0% (off). When the coordinates of both the lateral and longitudinal axis are 255, the brightness of the switch illumination will be 100% (full brightness).

(d) Switch Operation Check

(1) Check that the switch illumination turns on at 100% brightness when each switch is pressed while touching the upper left of the remote touch screen.

HINT:

If the switch illumination turns on at 100% brightness when a switch is pressed, the switch being pressed is operating normally.

(e) Vibration feedback generation condition check

(1) Operate the remote touch screen to move the pointer displayed on the multi-display assembly screen and check that remote touch screen generates vibration feedback according to the pointer display position on the multi-display assembly.

*a	Feedback Force Image Screen
*b	Button

HINT:

On the multi-display assembly customize setting screen, if the feedback force setting is set to "Off", no vibration feedback will be generated.
If the remote touch screen generates vibration feedback according to the pointer display position, the remote touch (remote operation controller assembly) is correctly receiving the reaction force setting signal sent from the radio receiver assembly.
If the remote touch (remote operation controller assembly) cannot receive the reaction force setting signal sent from the radio receiver assembly, use the default feedback force image stored in the remote touch (remote operation controller assembly) to generate vibration feedback on the remote touch screen.

(f) End Self-diagnostic Mode

(1) Do not perform any operations for 30 seconds, or turn the engine switch off to end self-diagnostic mode.
