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”.

4. Accelerate vehicle to 35 to 40 km/h (22 to 25 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 “ON”)
lCheck that “GEAR” shows “3” or “4” after releasing pedal.
5. Depress accelerator pedal to WOT (more than 7.0/8 of “THROT-
TLE POSI”) quickly from a speed of 35 to 40 km/h (22 to 25
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-162,
"Diagnostic Procedure".
If “STOP VEHICLE” appears on CONSULT-II screen, go to following step.
lCheck that “GEAR” shows “2” 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 P0732 is shown, refer to applicable “TROUBLE DIAG-
NOSIS FOR DTC”.
