Make sure that “GEAR” shows “4” after releasing pedal.
6. Depress accelerator pedal steadily with 3.5/8 - 4.5/ 8 of “THROTTLE POSI” from a speed of 60 to 75 km/h
(37 to 47 MPH) until “TESTING” changes to “STOP VE HICLE” or “COMPLETED”. (It will take approxi-
mately 3 seconds.)
If the check result NG appears on CONSULT-III screen, go to AT-117, " Diagnosis Procedure " .
If “STOP VEHICLE” appears on CONSULT-III screen, go to following step.
- Make sure that “GEAR” shows “3” when depr essing accelerator pedal with 3.5/8 - 4.5/8 of
“THROTTLE POSI”.
- If “TESTING” does not appear on CONSULT-III fo r a long time, select “SELF-DIAG RESULTS” for
“TRANSMISSION”. In case a DTC ot her than “P0733 A/T 3RD GR FNCTN” is shown, refer to AT-79," CONSULT-III Function (TRANSMISSION) " .
7. Stop vehicle.
8. Follow the instruction displayed. (Check for normal shifting referring to the table below.)
9. Make sure that “OK” is disp layed. (If “NG” is displayed, refer to “Diagnostic Procedure”.)
Refer to AT-117, " Diagnosis Procedure " .
Refer to AT-64, " Vehicle Speed at Which Gear Shifting Occurs " .
WITH GST
Follow the procedure “WITH CONSULT-III”.
Diagnosis Procedure INFOID:00000000043053821.
