Shift Position Indicator Circuit

SHIFT POSITION INDICATOR CIRCUIT

Description

TCM transmit the switch signals to unified meter and A/C amp. via CAN communication line. Then manual mode switch position is indicated on the shift position indicator.


Component Function Check


1. CHECK A/T INDICATOR


CAUTION:
Always drive vehicle at a safe speed.
1.Start the engine.
2.Check the actual selector lever position ("P", "R", "N", "D" and "DS") and the indication of the shift position indicator mutually coincide.
3.Drive vehicle in the manual mode, and then check that the actual gear position and the indication of the shift position indicator mutually coincide when the selector lever is shifted to "UP (+ side)" or "DOWN (-side)" side (1GR from/to 7GR).
Is the inspection result normal?
YES- INSPECTION END
NO- Go to .


Diagnosis Procedure


1. CHECK INPUT SIGNALS

With CONSULT-III
1.Start the engine.
2.Select "SLCT LVR POSI" in "Data Monitor" in "TRANSMISSION".
3.Check the actual selector lever position ("P", "R", "N", "D" and "DS") and the indication of the "SLCT LVR
POSI" mutually coincide. 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). 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. P1815.
- Check A/T main system (Fail-safe function actuated).
- Perform "Self Diagnostic Results" in "TRANSMISSION". Testing and Inspection.
NO-2 (The actual gear position changes, but the shift position indicator is not indicated.)-Perform "Self
Diagnostic Results" in "TRANSMISSION". 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". Testing and Inspection.
NO-4 (Only a specific position or positions is/are not indicated on the shift position indicator.)-Check the combination meter. Unified Meter and A/C Amp.
