(c) Service check mode
(1) After the element check and switch check is completed, the system enters service check mode
when ºTUNE UPº switch is pressed.
(2) Error codes over the tuner and connected equipments are displayed on the screen of the 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 indicates ºCheckº is identified.
Old:
Application of old version is confirmed by the ºDiagnosis On Checkº, and DTC is identified
in the ºSystem Check Result Responseº or ºDiagnosis Memory Responseº.
nrES:
No response is identified to the ºSystem Check Start Instructionº and ºRequest for System
Check Resultº commands.
HINT:
Check the present and past condition of components by performing the System Check and collecting
stored DTC memories.
Check results are displayed as one of the following six indications: ºgoodº, ºECHnº, ºCHECº,ºnConº,
ºOldº or ºnrESº.
