Operation Check [09/2015 - 08/2020]

CHECK NAVIGATION SYSTEM NORMAL CONDITION

If the cause of a symptom is any of the following, the corresponding symptom is normal; it is not a malfunction.

Symptom	Answer
A longer route than expected is chosen.	Depending on the road conditions, the multi-media module receiver assembly 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 engine starts, the navigation system deviates from the correct 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 correct position.	When the vehicle is driving on new roads not available on the SD card, the system attempts to match it to another nearby road, causing the position mark to deviate.

The following symptoms are not malfunctions, but are caused by errors inherent in the GPS, gyro sensor, speed sensor or multi-media module receiver assembly.

  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.

REMOTE TOUCH SELF CHECK

NOTE:

Before performing the remote touch self check, check that there is no foreign matter that may interfere with remote touch switch knob operation and that the knob is not stuck.
To avoid interruption of remote touch switch knob operation, do not touch the knob unless instructed.

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

Activate Self Check Mode

Check that the remote touch switch knob automatically moves to the center of the movable area and the switch illumination blinks.

HINT:

When DTCs are stored as present DTCs during the self check, the 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 disappears, allowing the knob to automatically move to the center of the movable area.

Remote Touch Switch Knob Position Recognition Check

Fig 13: Remote Touch Switch Knob Axes

Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002

Move the remote touch switch knob up, down, right and left to check that the brightness of the 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 switch 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).

TEXT IN ILLUSTRATION

* b	Longitudinal Axis
* c	Lateral Axis

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

Remote Touch Switch Knob Feedback Force Check

Fig 14: Remote Touch Switch Knob Feedback Force

HINT:

Refer to Remote Touch Outline in System Description for further information on the remote touch switch knob feedback force generated according to the screen being displayed and the pointer position. Refer to SYSTEM DESCRIPTION [09/2015 - ] .
When the feedback force of the remote touch switch knob changes according to the screen being displayed and the pointer position, the remote touch is receiving feedback force request signals from the multi-media module receiver assembly.
When the remote touch cannot receive feedback force request signals from the multi-media module receiver assembly, the remote touch generates feedback force according to the default feedback force image recorded in the remote touch (remote operation board).

CHECK "Bluetooth" CONNECTION HISTORY

HINT:

This function is used to check the connection history when the connection between the multi-media module receiver assembly and a "Bluetooth" device is unstable.

Check "Bluetooth" Connection History.

HINT:

"Bluetooth" Connection History displays data stored in the internal memory of the ECU, such as the date a "Bluetooth" connection was attempted and the progress of a "Bluetooth" connection.
By checking "Bluetooth" Connection History, the date, cause, etc. of a "Bluetooth" device failing to register or connect can be analyzed.
"Bluetooth" connection history indicates the estimated cause of a malfunction, but does not determine it. Therefore, checking "Bluetooth" Connection History may not improve the problem.
Performing inspection using the Techstream before recording the "Bluetooth" Connection History may clear the operation history.

Connect the Techstream to the DLC3.
Turn the engine switch on (IG).
Turn the Techstream on.
Enter the following menus: Body Electrical / Navigation System / Utility / "Bluetooth" Connection History.

When an item is stored for "Bluetooth" Connection History, record it before proceeding with troubleshooting.
