Component Tests and General Diagnostics

Touch Screen Display (TSD) and Navigation Diagnostics
The TSD and the navigation module both have built in self tests that allow the technician to diagnose fault conditions. Fault codes and diagnostics can also be retrieved/achieved using the manufacturer approved diagnostic system.

TSD Diagnostics
The TSD has in built diagnostics to aid the diagnosis of system faults. The diagnostics allow the technician to interrogate the following:
- Hard Key Test
- Touch Switch Test
- DTC Information
- Vehicle Configurations
- Configurations
- Vehicle Signals
- Video Inputs Test
- Self Test
- MOST Test
- Colour bar
- Loading
- HDD information
- Vehicle information
- Microphone
- Voice output check
The built in diagnostics are accessed as follows:
- Once the system is powered up enter the 'Home' menu page
- Press and hold the TSD in the centre at the top of the screen for approximately 5 seconds and then press and hold the TSD at the top left corner of the screen for approximately 5 seconds.
- A 'Diag PIN Entry' box will appear' Type in the access code 753
- Once this code has been accepted the Diagnostic Menu screen will be displayed
Hard Key Test
The hard key test is used to check the operation of the hard switches.
If switch operation is normal, the switch colour on the screen will change when a hard switch is pressed. (Power switch operation cannot be checked on this screen.)
Touch Switch Test
The touch switch test calibrates the touch switch coordinates and checks touch switch operation.
Start Calibration - Calibrates the switch coordinates. Calibrate the coordinates by touching each of the "+" marks in the four corners of the screen.

NOTE:
Do not touch any locations other than the "+" marks. (Touching other locations may invalidate the calibration.)
Touch Switch Check - Checks for deviation in the coordinates. Check the coordinates of the touched location by verifying the displayed values. Touch and hold "press here" to return to the previous screen. If there is a large deviation in the coordinates, calibrate the touch switch using the "Start Calibration" function.
DTC Information
Search for the meaning of the displayed DTC.
Vehicle Configurations
Display the status of each vehicle system.
Speed Lock Configuration - Display the status of compulsory navigation settings (setting status of switches that cannot be operated) when driving.
Configurations
Display primary system information.
Vehicle Signals
Display the status of vehicle signals inputted to the Touch Screen Display (TSD). These signals include:
- Lights (on or off)
- Ambient light sensor voltage
- Backlight dimming duty
- Graphic illumination dimming duty
- Vehicle speed, GPS speed, MOST km/h
- Battery voltage
- Reverse gear / Parking brake position (electric park brake on or off)
- Speed inhibit
- MOST Fibre Optic Transceiver (FOT) temperature
- Output audio allocation
Video Inputs Test
This screen will allow the testing of video inputs that are connected to the Touch Screen Display (TSD). These include:
- Companion camera
- Rear view / Proximity camera
- TV/DVD
Self Test
Performs system self-diagnosis and displays the diagnostic results.
If an abnormality is present, a DTC is displayed.
MOST Test
Display the MOST connection status, and reception/transmission messages related to MOST.
"Mpr" displays the number of MOST devices existing on MOST. When "0" or "1" is displayed, communication is not possible.
Colour bar
This function allows the technician to test the colors generated by the TSD. A second screen displays six solid colors, selecting the colour will fill the screen with the chosen colour and pressing the TSD again will revert back to the colour test screen.
Loading
Update the navigation program.
For details on the update method, refer to the "Navigation Update Tool" operation manual.
HDD information
Display information on the Hard Disc Drive (HDD).
SMART test (Self-Monitoring Analysis and Reporting Technology) is initiated from this screen
Vehicle information
Display information on the vehicle.
- Car configuration - Displays information on vehicle environment settings.
- Unit (distance) - Units of distance
- Unit (time) - Units of time
- Language - Displayed language
- Fuel information - Remaining fuel quantity
- Mileage information - Vehicle mileage display
- Time information - Current time display
- Override information - Status of switch operation inhibitions (Setting status of switches that cannot be operated.)
- GPS information - Display GPS related information.
- Received position - Displays the latitude and longitude (displayed in degrees, minutes, and seconds) for the position information calculated by GPS.
- Map matched position - Displays the latitude and longitude (displayed in degrees, minutes, and seconds) for the position information being used for map matching.
- Satellites - Number of acquired satellites.
- Current address - Address of the current location.
- Satellite Information - Displays satellite information for up to 12 GPS satellite search targets.
- Measurement HDOP - Positioning accuracy.
- Status - Positioning status.

- Vehicle sensor - Display vehicle signals inputted to the Touch Screen Display (TSD).
- REV - Reverse signal status.
- Speed - Current vehicle speed.
- Speed pulse count - Speed pulse count value.
- Distance calibration - Learning information for distance calibration.
- Voltage/Offset - Gyro sensor output voltage value/voltage correction value.
- Relative bearing - Relative bearing (0° when navigation is started.)
- Gyro sense - Learning value for gyro sensitivity.
- Reset - Resets the gyro sensor relative bearing value.
- RDS-TMC information - Display RDS-TMC related information.
- Date/time (GMT) - Date and time for the TMC signal.
- Frequency - TMC signal frequency.

Microphone
Check the volume for the voice recognition microphone inputted to the Touch Screen Display (TSD). These include:
- PTT switch status - Checks the PTT switch connection. When the PTT switch is pressed, a signal will be outputted, and the indicator displays in green.
- Microphone input level judging - If a sampling of the user's voice command is at or above the threshold value, the indicator displays in blue.
- Microphone level - Displays the microphone input level.
Voice output check
Check the audio output.
- ON (Normal) - Outputs ADPCM voice (1 kHz sine wave) for five seconds.
- ON (Max) - Outputs ADPCM voice (maximum 1 kHz sine wave) for five seconds.
