- Actual position of the selector lever
- “SLCT LVR POSI” on CONSULT-III screen
- Shift position indicator in the combination meter
OK or NG
OK >>INSPECTION END
NG >> Check the following.

any position.
Perform the self-diagnosis for A/T and the combination meter.
• Refer to AT- 7 3 , "
CONSULT-III Function (A/T)" 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.
