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.
