Operation Check

1. If the symptom is applicable to any of the following, it is intended behavior, and not a malfunction.

   Symptom	Answer
   A longer route than expected is chosen.	Depending on the road conditions, the display and navigation module display may determine that a longer route is quicker.
   Even when distance priority is high, the shortest route is not shown.	Some routes may not be advised due to safety concerns.
   When the vehicle is put into motion immediately after the hybrid system starts, the navigation system deviates from the current position.	If the vehicle starts before the navigation system activates, the system may not react.
   When driving on certain types of roads, especially new roads, the vehicle position deviates from the current position.	When the vehicle is driving on new roads not available on the map data from the hard disk drive, the system attempts to match it to another nearby road, causing the position mark to deviate.

2. The following symptoms are not malfunctions, but are caused by errors inherent in the GPS, gyro sensor, speed sensor or display and navigation module display.

   1. The current position mark may be displayed on a nearby parallel road.
   2. Immediately after a fork in the road, the current vehicle position mark may be displayed on the wrong road.

   10. When the tires are changed, the current vehicle position mark may deviate from the correct position.
       Fig 10: Identifying Vehicle Position Mark In Correct Position - Tire Change

       Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002

       HINT: 

       • A change in tire diameter may cause a speed sensor error.
       • Performing "tire change" in calibration mode will allow the system to correct the current vehicle position faster.

HINT: 

• The remote touch performs initialization of its knob position at the time the vehicle is started and turned off.
• When remote touch switch knob position initialization fails, DTC B1581 will be stored.

1. Move the remote touch switch knob to a position other than the center and turn the power switch on (ACC).
2. Check that the remote touch switch knob moves automatically to the center of the movable area.

   HINT: 

   • Initialization of the remote touch switch knob position is complete when the knob moves to the center of the movable area.
   • If remote touch switch knob position initialization fails, remote touch switch knob operation and pointer movement on the screen will not match.
   • If the remote touch switch knob does not move to the center of the movable area within 10 seconds because of foreign objects or the knob being stuck, the remote touch will stop operating.
   • When the foreign object is removed or the remote touch switch knob is freed, and the knob position changes, the knob moves to the center of the movable area and completes its initialization.
   • The remote touch will repeatedly try to initialize itself until initialization has been completed, except when a built-in motor has a malfunction.
3. Move the remote touch switch knob to a position other than the center and turn the power switch off.
4. Check that the remote touch switch knob automatically moves to the center of the movable area.

   HINT: 

   • Initialization of the remote touch switch knob position is complete when the knob moves to the center of the movable area.
   • If the remote touch switch knob does not move to the center of the movable area within 3 seconds because of foreign objects or the knob being stuck, the remote touch will stop operating. In this case, initialization of the knob position will not complete, but DTC B1581 will not be stored.

HINT: 

The following checks can be done via the self check:

• DTC check for the remote touch
• Switch illumination check
• Remote touch switch knob position recognition check
• Switch operation check
• Remote touch switch knob feedback force check

1. Activate Self Check Mode
   Fig 11: Identifying Down Seesaw & "DISP" Switch

   Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
   1. Turn the power switch on (ACC) with the "DISP" switch and the down seesaw switch pressed to activate self check mode.
2. Switch Illumination Check and DTC Check
   1. Check that the remote touch switch knob automatically moves to the center of the movable area and that the "MAP/VOICE" and "MENU" switch illumination turns on.
      Fig 12: Identifying Switch Illumination & Switch Knob

      Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002

      HINT: 

      • If the remote touch switch knob does not automatically move to the center of the movable area, DTC B1581 is stored.
      • When a DTC is stored as a present DTC during self check, the "MAP/VOICE" and "MENU" switch illumination blinks at 0.5-second intervals. The illumination will continue to blink until the self check is completed.
      • The switch illumination stops blinking only when the factor that caused the remote touch switch knob malfunction (DTC B1581) disappears, allowing the knob to automatically move to the center of the movable area.
3. Remote Touch Switch Knob Position Recognition Check
   Fig 13: Identifying Remote Touch Switch Knob Position Recognition Check

   Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
   1. Move the remote touch switch knob up, down, right and left to check that the brightness of the "MAP/VOICE" and "MENU" switch illumination changes.

      HINT: 

      • If the brightness changes according to remote touch switch knob operation, the knob position is being recognized normally.
      • The brightness of the switch illumination changes between 0 and 100% according to the coordinates of the remote touch switch knob.
      • The coordinates of the remote touch switch knob change between 0 and 255 for both the lateral and longitudinal axes.
      • When the coordinates of both the lateral and longitudinal axes of the remote touch switch knob are 0, the brightness of the switch illumination becomes 0% (the lights will be off), and when the coordinates of both axes of the knob are 255, the brightness of the switch illumination becomes 100% (the switch lights will be on at full brightness).
4. Switch Operation Check
   1. With the remote touch switch knob in the lower left position, check that pressing each switch on the remote touch turns on the "MAP/VOICE" and "MENU" switch illumination at 100% brightness.

      HINT: 

      If the "MAP/VOICE" and "MENU" switch illumination turn on when a switch is pressed, the switch being pressed is operating normally.

5. Remote Touch Switch Knob Feedback Force Check
   Fig 14: Checking Touch Switch Feedback Force & Movement Direction

   Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
   1. Move the remote touch switch knob up, down, right and left to check that feedback force is generated.

      HINT: 

      The motors built into the remote touch generate feedback force according to the direction in which the remote touch switch knob is moved.

   2. Move the pointer on the screen by operating the remote touch switch knob and check that the feedback force of the knob changes according to the screen being displayed and the pointer position.

      HINT: 

      • Refer to Remote Touch Outline for further information on remote touch switch knob feedback force generated according to the screen being displayed and the pointer position. Refer to SYSTEM DESCRIPTION .
      • When the feedback force of the remote touch switch knob changes according to the screen being displayed and the pointer position, it means that the remote touch is receiving feedback force request signals from the display and navigation module display.
      • When the remote touch cannot receive feedback force request signals from the display and navigation module display, the remote touch generates feedback force according to the default feedback force image recorded in the remote touch (remote operation board).
