3. Install pressure gauge to corresponding line pressure port.
4. Set parking brake and block wheels.
IContinue to depress brake pedal fully while line pressure
test is being performed at stall speed.
5. Start engine and measure line pressure at idle and stall speed.
IWhen measuring line pressure at stall speed, follow the
stall test procedure.
Line pressure: Refer to SDS, AT-120.
Road TestNCAT0028DESCRIPTIONNCAT0028S01IThe purpose of the test is to determine overall performance of
CVT and analyze causes of problems.
IThe road test consists of the following three parts:
1. Check before engine is started
2. Cruise test
IBefore road test, familiarize yourself with all test procedures
and items to check.
IConduct tests on all items until specified symptom is found.
Troubleshoot items which check out No Good after road test.

DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION
PROCEDURE
NCAT0032S03CAUTION:
Always drive vehicle at a safe speed.
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 CVT fluid temperature sne-
sor 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
15 consecutive seconds.
VHCL SPEED SE: 10 km/h (6 MPH) or more
THRTL POS SEN: More than 1.3V
Selector lever: D position
ENG SPEED: 450 rpm or more
If the check result is ªNGº, go to ªDiagnostic Procedureº,
AT-51.
With GST
Follow the procedure ªWith CONSULT-IIº.
