Audio and Visual System (w/o Multi-Display)





AUDIO / VISUAL: AUDIO AND VISUAL SYSTEM (w/o Multi-display): DTC CHECK / CLEAR

HINT
* Only premium sound models have DTCs.

1. STARTING DIAGNOSTIC MODE





(a) Turn off the audio system and turn the engine switch to ACC. While pressing the preset switches "1" and "6" at the same time, press the "CD" switch 3 times.





2. ALL ELEMENT ILLUMINATE MODE AND SWITCH INSPECTION MODE

HINT
* When the system enters the diagnostic mode, a "beep" sound is emitted 3 times and all the elements turn on during the switch check mode.
* It takes about 40 seconds to complete the check.
* All elements on the LCD will illuminate. Check that the illuminating elements are not malfunctioning.
* When pressing a switch, confirm that a beep sound is emitted. At that time, press the SEEK TRACK UP switch to a mode where the stereo jack adapter connection check can be performed.
3. AUX ADAPTER

(a) Press the "SEEK TRACK UP" switch.





(b) Check if the aux adapter has been recognized.

HINT
Even if the vehicle does not have an aux adapter, this recognition function is available.

NOTICE:
This recognition function is for checking the recognition information of the aux adapter. This function is not for checking the connection information of external devices.

4. SERVICE CHECK MODE

(a) Press the "SEEK TRACK UP" switch.

HINT
For details about the service check mode, refer to the "CHECK DTC" and "DTC CLEAR/RECHECK procedures.

5. FINISHING DIAGNOSTIC MODE

(a) Press the "CD" switch for 2 seconds or more, or turn the engine switch off.

6. CHECK DTC

HINT
Illuminations may differ from the actual vehicle depending on the device setting and options. Therefore, some detailed areas may not be shown exactly the same as on the actual vehicle.

(a) Reference:

In the system check mode, the system check and the diagnostic memory check are performed, and the check results are displayed in ascending order of the component codes (physical address).





(b) Service check result display





(c) Device name and physical address.





(d) Service check mode.

(1) Press the "SEEK TRACK" switch to see the check result of each component.

(2) The component code (physical address) is displayed first, and then the check result follows.

HINT
* If all check results are "good", the system judges that no DTC exists.
* If the preset switch "1" is pressed in the service check mode, service check is performed again.
* This illumination is only an example and may differ in cases such as for each option part and output DTCs.





(e) Detailed information mode 1

HINT
* "Detailed information mode 1" is displayed when there is no response to "System Check Result Request" and DTC is detected only in "Diagnostic Memory Request".
* The component device code (physical address) is displayed first, and then the check result follows.
* This illumination is only an example and may differ in cases such as for each option part and output DTCs.
(1) Press the preset switch "2" to go to the "Detailed Information Mode 1".

(2) Press the "SEEK TRACK" switch to display the physical address and DTC of the component.

(3) Press the preset switch "3" to go to the "Service Check Mode".

(4) Distinguish between the displays of the responses to "System Check Result Request" and "Diagnostic Memory Request". In order to distinguish the information detected in "System Check Mode" and "Diagnostic Memory Mode" in "ECHn", "CHEC", and "old" in "Detailed Information Mode 1", refer to the following:

* "SyS" is displayed before the detailed codes detected as a result of "System Check Result Request" are displayed.

* "CodE" is displayed before the detailed codes detected as a result of "Diagnostic Memory Request" are displayed.

HINT
* The response to "System Check Result Request" is the current information given from each ECU as a result of the system check.
* The response to "Diagnostic Memory Request" contains the information received from each ECU or stored in each ECU in the past.
* The response to "Diagnostic Memory Request" is that DTCs as a result of the diagnostic memory check are output, or the DTCs received from each ECU.
* "System Check Result Request (SyS)" is displayed first, and then the logical address and DTC appear in order.
* "Diagnostic Memory Request (CodE)" is displayed first, and then the logical address, DTC, sub-code, connection check number, and the number of occurrence appear in order.





(f) Detailed information mode 2

HINT
* "Detailed information mode 2" is displayed when DTCs are detected in the responses to both "System Check Result Request" and "Diagnostic Memory Request".
* The component device code (physical address) is displayed first, and then the check result follows.
* This illumination is only an example and may differ in cases such as for each option part and output DTCs.
(1) Press the preset switch "2" to go to the "Detailed Information Mode 2".

(2) Press the "SEEK TRACK" switch to display the physical address and DTC of the component.

(3) Press the preset switch "3" to go to the "Service Check Mode".

(4) Distinguish between the displays of the responses to "System Check Result Request" and "Diagnostic Memory Request". In order to distinguish the information detected in "System Check Mode" and "Diagnostic Memory Mode" in "ECHn", "CHEC", and "old" in "Detailed Information Mode 2", refer to the following:

* "SyS" is displayed before the detailed codes detected as a result of "System Check Result Request" are displayed.

* "CodE" is displayed before the detailed codes detected as a result of "Diagnostic Memory Request" are displayed.

HINT
* The response to "System Check Result Request" is the current information given from each ECU as a result of the system check.
* The response to "Diagnostic Memory Request" contains the information received from each ECU or stored in each ECU in the past.
* The response to "Diagnostic Memory Request" is that DTCs as a result of the diagnostic memory check are output, or the DTCs received from each ECU.
* "System Check Result Request (SyS)" is displayed first, and then the logical address and DTC appear in order.
* "Diagnostic Memory Request (CodE)" is displayed first, and then the logical address, DTC, sub-code, connection check number, and the number of occurrence appear in order.





7. DTC CLEAR/RECHECK





(a) Clearing all DTC Memory (when clearing all the memory of the DTCs previously detected).

(1) When the preset switch "5" is pressed for 2 seconds or more during "Service Check Mode", the DTCs for all components are cleared. ("Clr" is displayed at this time.)

HINT
* A beep sound is emitted once when the DTC memory is completely cleared.
* When the DTC memory for all the components is cleared, only the component codes (physical address) are displayed.
