DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE

CAUTION:

Always drive vehicle at a safe speed.

Be 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.
TESTING CONDITIONS:
Always drive vehicle on a level road to improve the accuracy of
test.
After the repair, perform the following procedure to confirm the mal-
function 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  “2ND GR FNCTN P0732” of “DTC WORK SUPPORT”
mode for “A/T” with CONSULT-II and touch “START”.

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 1/8 (at all times during step 4)
Selector lever: D position (O/D ON)

Check that “GEAR” shows 3 or 4 after releasing pedal.

5.

Depress accelerator pedal to WOT (more than 7/8 of “THROT-
TLE POSI”) quickly from a speed of 50 to 55 km/h (31 to 34
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 

AT-279, "Diagnostic Procedure"

 .

If “STOP VEHICLE” appears on CONSULT-II screen, go to following step.

Check that “GEAR” shows 2 when depressing accelerator pedal to WOT.

If “TESTING” does not appear on CONSULT-II for a long time, select “SELF-DIAG RESULTS” for
“ENGINE”. In case a 1st trip DTC other than P0732 is shown, refer to applicable “TROUBLE DIAG-
NOSIS FOR DTC”.
