DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION
PROCEDURE
NLAT0232S04CAUTION:
+Always drive vehicle at a safe speed.
+Be careful not to rev engine into the red zone on the
tachometer.
NOTE:
If ªDIAGNOSTIC TROUBLE CODE CONFIRMATION PROCE-
DUREº has been previously conducted, always turn ignition
switch ªOFFº and wait at least 5 seconds before conducting
the next test.
After the repair, perform the following procedure to confirm the
malfunction is eliminated.
With CONSULT-II
1) Turn ignition switch ªONº and select ªDATA MONITORº mode
for ªCVTº with CONSULT-II.
2) Make sure that output voltage of line temperature sensor is
within the range below.
FLUID TEMP SEN: 0.5 - 1.5V
If out of range, drive the vehicle to decrease the voltage
(warm up the fluid) or stop engine to increase the voltage
(cool down the fluid)
3) Select ªDATA MONITORº mode for ªENGINEº with CONSULT-
II.
4) Start engine and maintain the following conditions for at least
5 consecutive seconds.
VHCL SPEED SE: 10 km/h (6 MPH) or more
THRTL POS SEN: 1.3V
Selector lever: D position
ENG SPEED: 450 rpm or more
If the check result is NG, go to ªDiagnostic Procedureº, AT-123.
With GST
Follow the procedure ªWith CONSULT-IIº.
