1. Europe models:
DIAGNOSIS FUNCTION
(a) Diagnosis start-up
For shifting diagnosis mode, turn ignition switch ON and push the ºDISCº switch 3 times while pressing
ºch1º and ºch6º switches.
HINT:
To exist from the diagnosis mode, push the ºDISCº switch for 1.7 sec. or turn ignition switch to ACC or OFF.
(b) Service check mode
(1) After the diagnosis start-up, the system enters service check mode.
(2) Error codes over tuner and connected equipment are displayed on the screen of tuner.
Results for each check are displayed as follows:
good:
No DTC is detected for both ºSystem Check Confirmationº and ºDiagnosis Memory Re-
sponseº.
nCon:
The Component does not respond to the ºDiagnosis On Instructionº command.
Applicable to only the system where connected components are limited to be used.
ECHn:
Application of new version has been confirmed by the ºDiagnosis On Checkº, and there
is one or more DTC which indicates ºReplacementº in the ºSystem Check Result Re-
sponseº or ºDiagnosis Memory Responseº.
CHEC:
Application of new version has been confirmed by the ºDiagnosis On Checkº, and there
is no DTC which indicates ºReplacementº in the ºSystem Check Result Responseº or
ºDiagnosis Memory Responseº, but one or more DTC which indicated ºCheckº is identified.

2. Except Europe models:
DIAGNOSIS FUNCTION
Error codes over tuner and connected equipment are displayed on the screen of tuner.
(a) Diagnosis start-up
For shifting to diagnosis mode, push ºDISCº switch 3 times with pressing º1º and º6º of PRESET switch
at the same time while the audio power is OFF and ACC is ON.
To exit from diagnosis mode, press ºDISCº switch for 2 seconds or turn the ignition key OFF.
(When º1-190º is displayed, the mode is transferred to LAN check mode.)
(b) 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 ºUPº or ºDOWNº switch. In LAN check
mode, by pressing º5º 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
190Radio receiver assembly (Audio head unit)
240CD changer (in Luggage room)
360CD changer (in center console and glove compartment box)
440Power amplifier
(c) System check
When pressing º1º 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.(ºSYSº (showing the system is under detection) is displayed.)
Perform the operation shown in the following illustration, then read the result of the inspection.
