SDT Function (AT)

FUNCTION





SDT REFERENCE VALUE

NOTE:
1. The SDT electrically displays shift timing and lock-up timing (that is, operation timing of each solenoid).
Check for time difference between actual shift timing and the SDT display. If the difference is noticeable, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical parts using applicable diagnostic procedures.
2. Shift schedule (which implies gear position) displayed on SDT and that indicated in Service Manual may differ slightly. This occurs because of the following reasons:
^ Actual shift schedule has more or less tolerance or allowance,
^ Shift schedule indicated in Service Manual refers to the point where shifts start, and
^ Gear position displayed on SDT indicates the point where shifts are completed.
3. Display of solenoid valves on SDT changes at the start of shifting, while gear position is displayed upon completion of shifting (which is computed by TCM).
