5. Accelerate vehicle to 20 to 25 km/h (12 to 16 MPH) under the following conditions and release the accel-erator pedal completely.
THROTTLE POSI: Less than 1.0/8 (at all times during step 4)
SLCT LVR POSI: “D” position
- Make sure that “GEAR” shows “2” after releasing pedal.
6. Depress accelerator pedal to WOT (more than 7.0/8 of “THROTTLE POSI”) quickly from a speed of 20 to
25 km/h (12 to 16 MPH) until “TESTING” changes to “STOP VEHICLE” or “COMPLETED”. (It will take
approximately 3 seconds.)
If the check result NG appears on CONSULT-III screen, go to AT-110, "
Diagnosis Procedure".
If “STOP VEHICLE” appears on CONSULT- III screen, go to the following step.
- Make sure that “GEAR” shows “1” wh en 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 “P0731 1GR INCORRECT RATIO” is shown, refer to
AT-77, "
CONSULT-III Funct ion (TRANSMISSION)".
7. Stop vehicle.
8. Follow the instruction displayed. (Check for normal shifting referring to the table below.)
9. Make sure that “OK” is displayed. (If “NG” is displayed, refer to “Diagnostic Procedure”.)
