DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE
CAUTION:
lAlways drive vehicle at a safe speed.
lBe careful not to rev engine into the red zone on the
tachometer.
NOTE:
If “DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCE-
DURE” has been previously conducted, always turn ignition
switch “OFF” and wait at least 5 seconds before conducting the
next test.
After the repair, perform the following procedure to confirm the mal-
function is eliminated.
With CONSULT-II
1. Turn ignition switch “ON” and select “DATA MONITOR” mode for
“A/T” with CONSULT-II.
2. Drive vehicle and check for an increase of “VHCL/S SE·MTR”
value increase.
If the check result is NG, go to “DIAGNOSTIC PROCEDURE”,
AT-145, "
Diagnostic Procedure".
If the check result is OK, go to following step.
3. Select “DATA MONITOR” mode for “ENGINE” with CONSULT-II.
4. Start engine and maintain the following conditions for at least 5
consecutive seconds.
VHCL SPEED SE: 30 km/h (19 MPH) or more
THRTL POS SEN: More than 1.2V
Selector lever: D position (OD “ON”)
Driving location: Driving the vehicle uphill (increased
engine load) will help maintain the driving conditions
required for this test.
If the check result is NG, go to “DIAGNOSTIC PROCEDURE”,
AT-145, "
Diagnostic Procedure".
If the check result is OK, go to following step.
5. Maintain the following conditions for at least 5 consecutive sec-
onds.
CMPS·RPM (REF): 3,500 rpm or more
THRTL POS SEN: More than 1.2V
Selector lever: D position (OD “ON”)
Driving location: Driving the vehicle uphill (increased
engine load) will help maintain the driving conditions
required for this test.

DTC P0731 A/T 1ST GEAR FUNCTION
DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION
PROCEDURE
CAUTION:
lAlways drive vehicle at a safe speed.
lBe careful not to rev engine into the red zone on the tachometer.
NOTE:
If “DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE” has been previously conducted,
always turn ignition switch “OFF” 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 “DATA MONITOR” mode for “A/T” 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 “1ST GR FNCTN P0731” of “DTC WORK SUPPORT”
mode for “A/T” with CONSULT-II and touch “START”.
4. Accelerate vehicle to 15 to 20 km/h (9 to 12 MPH) under the fol-
lowing condition and release the accelerator pedal completely.
THROTTLE POSI: Less than 1.0/8 (at all times during step 4)
Selector lever: D position (OD “ON”)
lCheck that “GEAR” shows “2” after releasing pedal.
5. Depress accelerator pedal to WOT (more than 7.0/8 of “THROT-
TLE POSI”) quickly from a speed of 15 to 20 km/h (9 to 12 MPH)
until “TESTING” changes to “STOP VEHICLE” or “COM-
PLETED”. (It will take approximately 3 seconds.)
If the check result NG appears on CONSULT-II screen, go to
“DIAGNOSTIC PROCEDURE”,AT-155, "
Diagnostic Procedure".
If “STOP VEHICLE” appears on CONSULT-II screen, go to the following step.
lCheck that “GEAR” shows “1” when depressing accelerator pedal to WOT.
lIf “TESTING” does not appear on CONSULT-II for a long time, select “SELF-DIAGNOSIS” for
“ENGINE”. In case a 1st trip DTC other than P0731 is shown, refer to applicable “TROUBLE DIAG-
NOSIS FOR DTC”.
