- Diagnosis start-up For shifting to diagnosis mode, push "DISC" 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 "DISC" switch for 2 seconds or turn the ignition key OFF. (When "1-190" is displayed, the mode is transferred to LAN check mode.)
- 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 displayed 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. Code No. (physical address) List CODE NO. (PHYSICAL ADDRESS) EQUIPMENT NAME Code No. (physical address) Equipment name 190 Radio receiver assembly (Audio head unit) 240 CD changer (in Luggage room) 360 CD changer (in center console and glove compartment box) 440 Stereo component amplifier
- System check 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 results. ("SYS" (showing the system is under detection) is displayed.) Perform the operation (Scheme 43), then read the result of the inspection. HINT: It sometimes takes approx. 40 secs. till the system inspection is completed. The chart (Scheme 43)is an example of when diagnosis code "21" appears on the physical address (190) equipment. (ROM error occurs on the radio receiver.) The smaller code numbers (physical address) are displayed in order (code No., diagnosis code, support code of diagnosis code (object equipment)). 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. In the system check mode, when pressing "6" of PRESET switch the mode returns to LAN check mode.
- Diagnosis memory 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. Perform the operation (Scheme 44), then read the result of the inspection. HINT: The smaller code numbers (physical address) are displayed in order (code No. periodic communication number when error occurs, diagnosis code, and support code of diagnosis code (object equipment)). 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 diagnosis code is same as code in the system check mode. When pressing "6" of PRESET switch, the mode returns to LAN check mode. The illustration (Scheme 44)is an example of when diagnosis code "D1" appears on the code (190) and (240 or 360) equipment. (Communication error occurs between the radio receiver and CD changer.)
- Diagnosis memory clear After error is fixed, start up the diagnosis mode. Continue pressing preset switch "5" for 2 secs. (CLr is displayed.) Press the preset switch "2" and transfer to the diagnosis memory mode and check that the normal code (00) is output.

- Physical address 190: Radio receiver assembly Logical address: 01 (Communication control) Logical address: 61 (Cassette switch) HINT: *1: Even if no failure is detected, it may be stored depending on the battery condition or voltage for starting an engine. *2: It is stored when 180 sec. has passed after the power supply connector is pulled out after engine start. *3: It may be stored when the engine key is turned 1 min. again after engine start. *4: It may be stored when the engine key is turned again after engine start. *5: When 210 sec. has passed after pulling out the power supply connector of the master component with the ignition switch in ACC or ON, this code is stored.
- Physical address: 440 Stereo component amplifier
- Physical address: 360 CD Auto Changer Logical address: 63 (CD Auto Changer)
- Physical address: 1C6 Gateway ECU Logical address: 01 (Communication control) HINT: *1: When 210 sec. has passed after pulling out the power supply connector of the master component with the ignition switch in ACC or ON, this code is stored.
- 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.
- 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.
