Principles of Operation

The information in this section is intended to help with basic diagnosis of the navigation system.

For a detailed description of the Navigation System, refer to the relevant Description and Operation section in the Workshop Manual.

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:

The built in diagnostics are accessed as follows:

Hard Key Test Screen

The hard key test is used to determine the function of the two switches integrated into the TSD. Pressing either of the buttons will turn the corresponding icon on the screen green if it is functioning correctly.

Touch Screen Test Screen

Entering the Touch screen test screen allows the technician to test the physical side of the touch screen. The technician can choose between checking the screen integrity and re-calibrating the screen. Using the Touch Switch Check button will display a blank screen. Touching the screen in any place will give a series of co-ordinates. If a faulty area of the screen is touched the co-ordinates will not display.

Re-calibrating the screen allows the technician to align the touch screen co-ordinates to the pressing of the screen. This is achieved by pressing a series of on screen targets as they are displayed.

Vehicle Signals

The vehicle signals screen displays inputs from other vehicle systems to the TSD. These signals include:

Video Input Test

This screen will allow the testing of video inputs that are connected to the TSD. This includes TV/DVD Rear Seat Entertainment (RSE) and television.

RGB Color Test

This function allows the technician to test the colors generated by the TSD. A second screen displays six solid colors, selecting the color will fill the screen with the chosen color and pressing the TSD again will revert back to the color test screen.

Self Test

The self test function displays any fault codes that are present for the TSD. The screen also displays the current state of the ignition switch and the battery voltage.

Two additional buttons in the screen allow the technician to clear the fault codes and to test the TSD.

Configurations

The configurations screen displays information about the TSD and the navigation module. Switching between the two components is achieved via the soft key at the top LH corner of the screen.

The information contained in the screens is as follow:

Vehicle Configurations

Selecting the vehicle configurations option allows the technician to inspect the components installed to the vehicle entertainment system. There are four screens which can be navigated through via the next and previous buttons.

MOST Test

The MOST test screen displays information about the MOST signals being sent around the MOST ring. Using any part of the audio system will bring up the MOST message on the screen. This can be used to help diagnose MOST related faults.

Navigation Module Diagnostics

The navigation module has in built diagnostics to aid the diagnosis of system faults. The diagnostics allow the technician to interrogate the following:

Each area has a sub level of menus to access further information.

The built in diagnostics are accessed as follows:

Once this code has been accepted the on screen diagnostics menu will be displayed. The menu has the following options:

Navigation Info

The navigation info menu has three sub menus:

Parts Info

Parts info displays information on the system component and software versions.

Manual Check

The manual check menu enables the technician to complete the following self tests:

Self Check

Self check runs an internal check on the navigation module and displays any fault codes on the TSD.

Inspection and Verification

. Verify the customer concern.

. Visually inspect for obvious electrical faults.

:
  Time taken to lock on to satellites can be several minutes after ignition status is switched to 'ON'

It is possible for the GPS antenna to lose satellite reception in hilly or tree-lined areas, built-up areas, in multi-storey car parks, tunnels or during heavy rain or thunderstorms. Check for DTCs indicating an antenna or navigation module fault.
Touch screen display (TSD) displays a high temperature message and shuts down
  • MOST fibre optic transceiver (FOT) over-temperature
  • FOT temperature greater than 85°C
Check MOST FOT temperature in TSD diagnostics, vehicle signals. Once the temperature is reduced the system will resume normal operation. If the system does not resume normal operation, check for DTCs indicating an information and entertainment system fault.

DTC index

:
  If the control module is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty Policy and Procedures manual (section B1.2), or determine if any prior approval Program is in operation, prior to the installation of a new module.

:
  Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give additional information read by the manufacturer approved diagnostic system).

:
  When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal places, and with an up-to-date calibration certificate. When testing resistance, always take the resistance of the DMM leads into account.

:
  Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.

:
  Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.

:
  If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the cause. Always check for loose connections and corroded terminals.
