REMOTE TOUCH SELF CHECK
Note
Before entering self-diagnostic mode, make sure there are no obstructions which may interfere with operation of the touchpad, and that the touchpad is not dirty.
Do not touch the touchpad except when necessary.
Since the touchpad may recognize a pinch in/out or flick operation if operated with 2 fingers, always use 1 finger to operate the touchpad in self-diagnostic mode.
Tech Tips
The following checks can be done via self-diagnostic mode:
Remote touch DTC check
Switch illumination check
Touchpad operation position recognition check
Switch operation check
Vibration feedback generation condition check
| *a | "MENU" Switch |
| *b | Touchpad |
Activate Self-diagnostic Mode
Turn the light control switch to the tail or head position.
While touching the touchpad and pressing and holding the "MENU" switch, turn the engine switch on (ACC) to enter self-diagnostic mode.
Note
If the touchpad is not being touched when the engine switch is turned on (ACC), self-diagnostic mode will not be entered.
Switch Illumination Check and DTC Check
| *a | Switch Illumination |
Check that the switch illumination turns on.
Tech Tips
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 |
Touchpad operation position recognition check
Operate the touchpad laterally and longitudinally and check that the brightness of the switch illumination changes.
Tech Tips
If the brightness of the switch illumination changes according to the position touched on the touchpad, the touchpad operation position is correctly being recognized.
The brightness of the switch illumination changes between 0% and 100% according to the touchpad operation coordinates.
The touchpad operation coordinates change between 0 and 255 for the lateral axis and between 1 and 255 for the longitudinal axis.
When the touchpad operation coordinates are 0 for the lateral axis and 1 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).
Switch Operation Check
Check that the switch illumination turns on at 100% brightness when each switch is pressed while touching the lower left of the touchpad.
Tech Tips
If the switch illumination turns on at 100% brightness when a switch is pressed, the switch being pressed is operating normally.
Vibration feedback generation condition check
| *a | Feedback Force Image Screen |
| *b | Button |
Operate the touchpad to move the pointer displayed on the multi-display assembly screen and check that remote touch (remote operation controller assembly) generates vibration feedback according to the pointer display position on the multi-display assembly.
Tech Tips
On the multi-display assembly customize setting screen, if the feedback force setting is set to "LEVEL1 (No Vibration)", no vibration feedback will be generated.
If the remote touch (remote operation controller assembly) 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 to generate vibration feedback on the touchpad.
End Self-diagnostic Mode
Do not perform any operations for 30 seconds, or turn the engine switch off to end self-diagnostic mode.
