(2) If the above is not the problem, check the connections of the related harness connectors. If a
malfunctioning location is discovered, repair it and then re-check the trouble symptoms.
(3) If there are no abnormalities in the harness connections, check the harnesses themselves. If there
are no abnormalities in the harnesses, replace the relevant unit. Make a note of any error codes
and service function data generated at this time.
NOTE
If the cause of the problem seems to be related to system communication, carry out troubleshooting.
3. Notes on trouble diagnosis when only specific functions are abnormal
(1) If only certain functions are showing an abnormality, use the audio checking function of the service
functions to check the hardware switches.
(2) If the switch functions are normal, check the connections of the related harness connectors. If a
malfunctioning location is discovered, repair it and then re-check the trouble symptoms.
(3) If there are no abnormalities in the harness connections, check the harnesses themselves. If there
are no abnormalities in the harnesses, replace the unit which controls that function.
4. Notes on trouble diagnosis of the navigation function
(1) The vehicle positioning accuracy of the navigation function is limited because of the principle of operation
which it uses. Because of this, the system may be operating normally even though customers might
be reporting a problem.
Before carrying out troubleshooting, get as much information as possible from the customer regarding
things such as usage conditions and driving locations. If it is possible to judge from this that the
problem is not caused by a system abnormality, explain the principle of operation used by the navigation
function and how to utilize it effectively.
(2) If you find that there is a system abnormality, check according to the Inspection Chart Classified
by Trouble Symptoms in the Troubleshooting section.
