DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION
PROCEDURE
NJAT0283S03CAUTION:
+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.
TESTING CONDITION:
Always drive vehicle on a level road to improve the accuracy
of test.
After the repair, perform the following procedure to confirm the
malfunction is eliminated.
With CONSULT-II
1) Start engine and select ªDATA MONITORº mode for ªA/Tº with
CONSULT-II.
2) Make sure that output voltage of A/T fluid temperature sensor
is within the range below.
FLUID TEMP SEN: 0.4 - 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 ª2ND GR FNCTN P0732º of ªDTC WORK SUPPORTº
mode for ªA/Tº with CONSULT-II and touch ªSTARTº.
4) Accelerate vehicle to 50 to 55 km/h (31 to 34 MPH) under the
following condition and release the accelerator pedal com-
pletely.
THROTTLE POSI: Less than 1.0/8 (at all times during step
4)
Selector lever: D position (OD ªONº)
+Check that ªGEARº shows ª3º or ª4º after releasing pedal.
5) Depress accelerator pedal to WOT (more than 7.0/8 of
ªTHROTTLE POSIº) quickly from a speed of 50 to 55 km/h (31
to 34 MPH) until ªTESTINGº changes to ªSTOP VEHICLEº or
ªCOMPLETEDº. (It will take approximately 3 seconds.)
If the check result NG appears on CONSULT-II screen, go to
ªDIAGNOSTIC PROCEDUREº, AT-215.
If ªSTOP VEHICLEº appears on CONSULT-II screen, go to
following step.
+Check that ªGEARº shows ª2º when depressing accelera-
tor pedal to WOT.
+If ªTESTINGº does not appear on CONSULT-II for a long
time, select ªSELF-DIAGNOSISº for ªENGINEº. In case a
1st trip DTC other than P0732 is shown, refer to applicable
ªTROUBLE DIAGNOSIS FOR DTCº.
6) Stop vehicle.
7) Follow the instruction displayed. (Check for normal shifting
referring to the table below.)
