3. Check the actual selector lever position ("P", "R", "N" and "D") and the indication of the "SLCT LVR POSI" mutually coincide. Refer to Pinout Values and Diagnostic Parameters.
4. Drive vehicle in the manual mode, and then check that the actual gear position and the indication of the "SLCT LVR POSI" mutually coincide when the selector lever is shifted to the "UP (+ side)" or "DOWN (side)" side (1GR from/to 7GR). Refer to Pinout Values and Diagnostic Parameters.
Is the inspection result normal?
YES - INSPECTION END
NO-1 [The actual gear position does not change, or shifting into the manual mode is not possible (no gear shifting in the manual mode possible). Or the shift position indicator is not indicated.]- Check manual mode switch. Refer to P1815.
- Check A/T main system (Fail-safe function actuated).
- Perform "Self Diagnostic Results" in "TRANSMISSION". Refer to Testing and Inspection.
NO-2 (The actual gear position changes, but the shift position indicator is not indicated.)-Perform "Self
Diagnostic Results" in "TRANSMISSION". Refer to Testing and Inspection.
NO-3 (The actual gear position and the indication on the shift position indicator do not coincide.)-Perform "Self Diagnostic Results" in "TRANSMISSION". Refer to Testing and Inspection.
