  • 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.
SERVICE CHECK MODE

Press the "SEEK-TRACK up" switch.

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

Press the "DISC" switch for 2 seconds or more, or turn the ignition switch off.

CHECK DTC
  • HINT:
  • Illumination 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.

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).

TermsMeaning
Physical address (component code)Three-digit code (in hexadecimal) given to each component of AVC-LAN. Individual symbol is provided corresponding to each function.
Logical addressTwo-digit code (in hexadecimal) given to each function and component unit in each component of AVC-LAN.

Service check mode.

Press the "SEEK-TRACK" switch to see the check result of each component.

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 is stored.
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.

Detailed Information Mode 1

  • HINT:
"Detailed Information Mode 1" is displayed when there is no response to "System Check Result Request" and DTC is stored 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.

Press preset switch "2" to go to "Detailed Information Mode 1".

Press the "SEEK-TRACK" switch to display the physical address and DTC of the component.

Press preset switch "3" to go to "Service Check Mode".

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".
"COdE" is displayed before the detailed codes detected as a result of "Diagnostic Memory Request".
  • 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 or the DTCs received from each ECU are output.
"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 occurrences appear in order.

Detailed Information Mode 2

  • HINT:
"Detailed Information Mode 2" is displayed when DTCs are stored 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.

Press preset switch "2" to go to "Detailed Information Mode 2".

Press the "SEEK-TRACK" switch to display the physical address and DTC of the component.

Press preset switch "3" to go to "Service Check Mode".

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".
"COdE" is displayed before the detailed codes detected as a result of "Diagnostic Memory Request".
  • 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 or the DTCs received from each ECU are output.
"System Check Result Request (SYS)" is displayed first, and then the logical address and DTC appear in order.

When 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.
After the DTC memory is cleared, the "Service Check Mode" is restored.

Clearing Individual DTC Memory (when clearing the memory of the DTC previously detected individually).

When preset switch "5" is pressed for 2 seconds or more during "Detailed Information Mode 1" or "Detailed Information Mode 2", the DTCs for the target component are cleared.

  • HINT:
A beep sound is emitted once when the DTC memory is completely cleared.
When the DTC memory is cleared, only the component code (physical address) is displayed for target component.
After the DTC memory is cleared, the "Service Check Mode" is restored.
To check DTCs, press preset switch "1" and perform the system check again.

Press preset switch "1" to perform the service check again, and check that no DTCs are displayed for all the component codes (physical address).
