CHECK DTC |
- HINT:
- Illustrations may differ from the actual vehicle depending on the device settings and options. Therefore, some detailed areas may not be 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 addresses).Terms Meaning Component code
(Physical address)Three-digit code (in hexadecimal) given to each device included in AVC-LAN. Corresponding to its function, individual symbol is provided. Logical address Two-digit code (in hexadecimal) given to each function of each device included in AVC-LAN. Service check result display
Display Original word Meaning Action to be taken good Good (normal) No DTCs are detected in both "System Check Mode" and "Diagnostic Memory Mode". - nCon No connection The system recognized the component when it was registered, but the component gives no response to the "Diagnostic Mode ON Request". Check the power source circuit and the communication circuit of the component indicated by the component code (physical address). ECHn Exchange One or more DTCs for "Exchange" are detected in either "System Check Mode" or "Diagnostic Memory Mode". Go to the detailed information mode to check the trouble area in the DTC list. CHEC Check No DTCs are detected for "Exchange", but one or more DTCs for "Check" are detected in either "System Check Mode" or "Diagnostic Memory Mode". Go to the detailed information mode to check the trouble area in the DTC list. OLd Old version An old AVC-LAN version is identified and one or more DTCs are detected in either "System Check Mode" or "Diagnostic Memory Mode". - nrES No response The device gives no response to any "System Check Mode ON Request", "System Check Result Request", or "Diagnostic Memory Request". Check the power source circuit and the communication circuit of the component indicated by the component code (physical address). Device name and physical address
Physical address No. Name 190 Radio receiver 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 exists.
- If preset switch "1" is pressed in service check mode, the service check is performed again.
- This illustration is only an example and may differ in cases such as those in which optional parts are present or different DTCs are output.
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 illustration is only an example and may differ in cases such as those in which optional parts are present or different DTCs are output.
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".
"COdE" is displayed before the detailed codes detected as a result of "Diagnostic Memory Request".
- HINT:
- 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 the DTCs output as a result of the diagnostic memory check or the DTCs received from each ECU.
- "Diagnostic Memory Request" (COdE) is displayed first, and then the logical address, DTC, sub-code, connection check number, and number of occurrences appear in order.
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 illustration is only an example and may differ in cases such as those in which optional parts are present or different DTCs are output.
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".
It is necessary to distinguish between the displays of the responses to "System Check Result Request" and "Diagnostic Memory Request". In order to distinguish between 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 the DTCs output as a result of the diagnostic memory check 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 number of occurrences appear in order.
- "SyS" is displayed before the detailed codes detected as a result of "System Check Result Request".
DTC CLEAR/RECHECK |
Clearing All DTC Memory (when clearing all the memory of the DTCs previously detected)
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 addresses) are displayed.
- After the DTC memory is cleared, "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 of the target component is completely cleared.
- When the DTC memory is cleared, only the component code (physical addresses) is displayed for the target component.
- After the DTC memory is cleared, "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 addresses).
