1. DIAGNOSTIC CHECK Starting Diagnostic Mode (All elements come on during the SW check mode). Turn off the audio system and turn the ignition switch to the ACC position. While pressing the preset switches "1" and "6" at the same time, press the "DISC" 3 times. Reference: When the system enters the Diagnostic Mode, a beep sound is emitted 3 times and all the elements come on during the SW check mode. It takes about 40 seconds to complete the check. Turn all the elements in the LCD on. When pressing the switch, confirm a beep sound is emitted. Service Check Screen. Press the "SEEK TRACK" switch to enter the "Service Check Screen". In the service 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.) COMPONENTS CODE CHART Terms Meaning Component code (Physical address) Three-digit code (in hexadecimal) given to each device comprising AVC-LAN. Corresponding to its function, individual symbol is provided. Logical address Two-digit code (in hexadecimal) given to each function and device unit in each device comprising AVC-LAN. EQUIPMENT NAME DESCRIPTION CHART Code No. (physical address) Equipment name 190 Radio receiver assy (Audio head unit) 440 Stereo component amplifier assy Finishing Diagnostic Mode. Press the "DISC" for 2 seconds or more, or turn the ignition switch off. Service Check Mode Result Display (for checking the current and the past system conditions). Press the "SEEK TRACK" switch to see the check result of each component. Check Result Display. ORIGINAL LANGUAGE DESCRIPTION CHART (1 OF 2) Display Original Language 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 referring to the DTC list. CHEC Check When no DTCs are detected for "Exchange", 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 referring to the DTC list. ORIGINAL LANGUAGE DESCRIPTION CHART (2 OF 2) Display Original Language Meaning Action to be taken OLD Old version Old DTC application is identified and DTC is detected in either "System Check Mode" or "Diagnostic Memory Mode". - NRES No response The device gives no response to any one of "System Check Mode ON Request", "System Check Result Request" and "Diagnostic Memory Request". Check the power source circuit and the communication circuit of the component indicated by the component code (physical address). To perform the Service Check again, press the preset switch "1". Detailed Information Mode (when displaying the DTC for a troubled component) With "CHECK" or "ECHN" being displayed, press the preset switch "2" to go to the detailed information mode. Press the "SEEK TRACK" switch to display the "System Check Result (SYS)" and "Diagnostic Memory Response (CODE)". Displayed Items in Detailed Information Mode Check the trouble area referring to the DTC list. To return to the service check mode, press the preset switch "3".

DTC CLEAR Clearing individual DTC memory (when clearing the memory of the DTC detected in the past individually) Press the preset switch "5" for 2 seconds or more while the "ECHN" is displayed in the service check mode or during the detailed information mode. 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 the target component. To check DTCs, press the preset switch "1" and perform the service check again. Clearing all the DTC memory (when clearing all the memory of the DTCs detected in the past) Start the diagnostic mode after repairing the trouble area. Press the preset switch "5" for 2 seconds or more ("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. Press the preset switch "1" to perform the service check again, and check that no DTCs are displayed for all the component codes (physical address). Finishing Diagnostic Mode. Press the "DISC" for 2 seconds or more, or turn the ignition switch off.

1. DISC CLEANING Disc cleaning If the disc gets dirty, clean the disc by wiping the surface from the center to outside in a radial direction with a soft cloth. NOTE: Do not use a conventional record cleaner or anti-static preservative. OK: Malfunction disappears. OK: DISC IS DIRTY NG: Go To Next Step
2. REPLACE CD WITH ANOTHER AND RECHECK Replace the CD with another and recheck. Replace the CD with another normal one to see if the same trouble occurs again. OK: Malfunction disappears. OK: CD IS FAULTY NG: Go To Next Step
3. CHECK RADIO RECEIVER ASSEMBLY INSTALLATION Check the radio receiver assembly installation condition. Check that the radio receiver assembly is installed properly. OK: Installed properly. NG: INSTALL THE RADIO RECEIVER ASSEMBLY PROPERLY OK: Go To Next Step
4. DID TEMPERATURE IN CABIN CHANGE RAPIDLY? Did the temperature in the cabin change rapidly? Check whether or not the rapid temperature change occurred in the cabin. OK: A rapid temperature change occurred. HINT: A rapid temperature change creates condensation inside the CD player, which may prevent the CD from being played. NG: REPLACE RADIO RECEIVER ASSY (SEE «RADIO RECEIVER ASSY»(ref-225927-S06258846072006032300000) ) OK: Go To Next Step CONDENSATION DUE TO TEMPERATURE CHANGE (LET IT SIT FOR A WHILE BEFORE USING)
