TROUBLESHOOTING
1.    DIAGNOSIS FUNCTION
Error codes over tuner and connected equipment are displayed on the screen of tuner.
(a) Diagnosis mode
      (1) Diagnosis start-up:
           For shifting to diagnosis mode, push "CD" switch 3 times with pressing "1" and "6" of PRESET
           switch at the same time while the audio power is OFF and ACC is ON.
           To exit from diagnosis mode, press "CD" switch for 2 seconds or turn the ignition key OFF.
           (When "1-190" is displayed, the mode is transferred to LAN check mode.)
      (2) LAN check:
           When starting up the diagnosis mode, the mode turns to LAN check mode, the screen displays
           the code numbers (physical address) of tuner and connected equipment. Smaller codes are dis-
           played in order, displayed code numbers are switched by operating TUNE "UP" or "DOWN"
           switch. In LAN check mode, by pressing "5" of PRESET switch for more than 2 secs., diagnosis
           memory of each equipment can be deleted, when deletion is completed, the mode returns to LAN
           check mode.


                                                                                      "CD" Switch




        TUNE "UP" or                                PRESET Switch
        "DOWN" Switch
                                                                                                               I12393




Code No. (physical address) List
            Code No. (physical address)                                            Equipment name
                       190                          Radio receiver assembly (Audio head unit)

(b)   System check
       S   When pressing "1" of PRESET switch in LAN check mode, the mode turns to the system check
           mode, the system performs self diagnosis of connected equipment and displays the re-
           sults.("SYS" (showing the system is under detection) is displayed.)
       S   Perform the operation shown in the following illustration, then read the result of the inspection.

HINT:
S       It sometimes takes approx. 40 secs. till the system inspection is completed.
S       The chart below is an example of when diagnosis code "21" appears on the physical address (190)
        equipment. (ROM error occurs on the radio receiver.)
S       The smaller code numbers (physical address) are displayed in order (code No., diagnosis code, sup-
        port code of diagnosis code (object equipment)).
S       When no error is detected in the system, "00" is displayed.
S       When an error code is detected, up to 6 codes per one system are displayed. Pressing TUNE "UP"
        or "DOWN" switches the display.
S       In the system check mode, when pressing "6" of PRESET switch the mode returns to LAN check mode.


                                                     H: This shows the equipment has a diagnosis code.

(c)     Diagnosis memory
        (1) In LAN check mode, when pressing "2" of PRESET switch the mode turns to the diagnosis
             memory mode. ("CODE" is displayed.)
             The results of self diagnosis performed over tuner and connected equipment are memorized and
             displayed.
        (2) Perform the operation shown in the following illustration, then read the result of the inspection.
HINT:
S       The smaller code numbers (physical address) are displayed in order (code No. , periodic communica-
        tion number when error occurs, diagnosis code, and support code of diagnosis code (object equip-
        ment)).
S       When no error is detected in the system, "00" is displayed. When an error code is detected, up to 6
        codes per one system are displayed. Pressing TUNE "UP" or "DOWN" switches the display. Each diag-
        nosis code is same as code in the system check mode.
S       When pressing "6" of PRESET switch, the mode returns to LAN check mode.
S       The following illustration below is an example of when diagnosis code "D1" appears on the code (190)
        and (360) equipment. (Communication error occurs between the radio receiver and CD changer.)

S    If there is "O" in the column of system check, an error can be detected when the mode is switched to
     the system check mode.
S    If there is "O" in the column of diagnosis mode, each unit is monitoring whether or not it has failure.
     In case of detecting failure, it memorizes DTC.

NOTICE:
When replacing the internal mechanism (computer part) of the audio system, be careful that no part
of your body or clothing comes in contact with the terminals of the leads from the IC, etc. of the re-
placement part (spare part).
HINT:
This inspection procedure is a simple troubleshooting which should be carried out on the vehicle during sys-
tem operation and was prepared on the assumption of system component troubles (except for the wires and
connectors, etc.).
Always inspect the trouble taking the following items into consideration.
 S    Open or short circuit of the wire harness
 S    Connector or terminal connection fault
