TROUBLE DIAGNOSIS
Engine Brake Adjustment
CAUTION:
Mode of “+1”“0”“-1”“-2”“OFF” can be selected by pressing the “UP”“DOWN” on CONSULT-III screen.
However, do not select mode other than “0” and “OFF”. If the “+1” or “-1” or “-2” is selected, that
might cause the irregular driveability.
Check CVT Fluid Deterioration Date
CAUTION:
Touch “CLEAR” after changing CVT fluid, and then erase “CVTF DETERIORATION DATE”.
SELF-DIAGNOSTIC RESULT MODE
After performing self-diagnosis, place check marks for results on the CVT-30, "How to Perform Trouble Diag-
nosis for Quick and Accurate Repair" . Reference pages are provided following the items.

• Overdrive control switch is installed to the selector lever.
• O/D OFF indicator turns ON, and overdrive driving activates when pressing the overdrive control switch
while driving in “D” position. O/D OFF indicator turns OFF, and “D” position driving starts when pressing the
overdrive control switch while driving in the overdrive-off mode. Shifting the selector lever in any position
other than “D” releases the overdrive-off mode.

1.CHECK INPUT SIGNALS
With CONSULT-III
1. Start engine.
2. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III and read
out the value of “RANGE”.
3. Check that the following three positions or indicators are same.
- Actual position of the selector lever
- “RANGE” on CONSULT-III screen
- Shift position indicator in the combination meter
