CONSULT-III Reference Value in Data Monitor ModeINFOID:0000000001703660
Diagnosis ProcedureINFOID:0000000001703661
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

• Refer to CVT-47, "
CONSULT-III Function (TRANSMISSION)".
Shift position indicator in the combination meter does not indicate
any position.
Perform the self-diagnosis for CVT and the combination meter.
• Refer to CVT-47, "
CONSULT-III Function (TRANSMISSION)"
and DI-4
. Actual position changes, but the shift position indicator in the com-
bination meter does not change.
Actual position differs from the shift position indicator in the com-
bination meter.
Shift position indicator in the combination meter does not indicate
specific position only.Check the combination meter.
