- Make sure that “GEAR” shows “3” or “4” after releasing pedal.
6. Depress accelerator pedal to WOT (more than 7.0/8 of “THROTTLE POSI”) quickly from a speed of 45 to 50 km/h (28 to 31 MPH) until “TESTING” changes to “STOP VEHICLE” or “COMPLETE”. (It will take
approximately 3 seconds.)
If the check result NG appears on CONSULT-III screen, go to AT-113, "
Diagnosis Procedure".
If “STOP VEHICLE” appears on CONSULT-III screen, go to following step.
- Make sure that “GEAR” shows “2” when depressing accelerator pedal to WOT.
- If “TESTING” does not appear on CONSULT-III fo r a long time, select “SELF-DIAG RESULTS” for
“TRANSMISSION”. In case a DTC other than “P0732 2GR INCORRECT RATIO” is shown, refer to
AT-77, "
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-113, "
Diagnosis Procedure".
Refer to AT-64, "
Vehicle Speed at Which Gear Shifting Occurs".
