+The A counter will be cleared when the malfunction is detected regardless of (1) - (4).
+The A counter will be counted up when (1) - (4) are satisfied without the same malfunction.
+The DTC will not be displayed after the A counter reaches 40.
Driving Pattern BNLEC1364S0602Driving pattern B means the vehicle operation as follows:
All components and systems should be monitored at least once by the OBD system.
+The B counter will be cleared when the malfunction is detected once regardless of the driving pattern.
+The B counter will be counted up when driving pattern B is satisfied without any malfunctions.
+The MI will go off when the B counter reaches 3 (*2 in EC-605).

REAL TIME DIAGNOSIS IN DATA MONITOR MODE
(RECORDING VEHICLE DATA)
NLEC1365S10CONSULT-II has two kinds of triggers and they can be selected by
touching ªSETTINGº in ªDATA MONITORº mode.
1) ªAUTO TRIGº (Automatic trigger):
+The malfunction will be identified on the CONSULT-II screen in
real time.
In other words, DTC/1st trip DTC and malfunction item will be
displayed if the malfunction is detected by ECM.
At the moment a malfunction is detected by ECM, ªMONITORº
in ªDATA MONITORº screen is changed to ªRecording Data ...
xx%º as shown at left, and the data after the malfunction detec-
tion is recorded. Then when the percentage reached 100%,
ªREAL-TIME DIAGº screen is displayed. If ªSTOPº is touched
on the screen during ª Recording Data ... xx%º, ªREAL-TIME
DIAGº screen is also displayed.
The recording time after the malfunction detection and the
recording speed can be changed by ªTRIGGER POINTº and
ªRecording Speedº. Refer to CONSULT-II OPERATION
MANUAL.
2) ªMANU TRIGº (Manual trigger):
