Shift Position Indicator Circuit
SHIFT POSITION INDICATOR CIRCUIT
Description
TCM transmit the switch signals to unified meter and A/C amp. by CAN communication line. Then manual mode switch position is indicated on the shift position indicator.
Component Function Check
1. CHECK A/T INDICATOR
1.Start the engine.
2.Check the actual selector lever position ("P", "R", "N" and "D") 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 position indicator mutually coincide when the selector lever is shifted to "UP (+ side)" or "DOWN (- side)"
side (1GR (double sided arrow) 7GR).
Is the inspection result normal?
YES- INSPECTION END
NO- Go to .
Diagnosis Procedure
1. CHECK INPUT SIGNALS
With CONSULT
1.Start the engine.
2.Select "SLCT LVR POSI" in "Data Monitor" in "TRANSMISSION".
3.Check the actual selector lever position ("P", "R", "N" and "D") and the indication of the "SLCT LVR POSI"
mutually coincide. 7AT RE7R01A.
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 (double sided arrow) 7GR). 7AT RE7R01A.
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. 7AT RE7R01A M-Mode Switch.
- Check A/T main system (Fail-safe function actuated).
- Perform "Self Diagnostic Results" mode for "TRANSMISSION". A L L Diagnostic Trouble Codes ( DTC ).
NO-2 (The actual gear position changes, but the shift position indicator is not indicated.)--Perform "Self
Diagnostic Results" mode for "TRANSMISSION". A L L Diagnostic Trouble Codes ( DTC ).
NO-3 (The actual gear position and the indication on the shift position indicator do not coincide.)--Perform
"Self Diagnostic Results" mode for "TRANSMISSION". A L L Diagnostic Trouble Codes ( DTC ).
NO-4 (Only a specific position or positions is/are not indicated on the shift position indicator.)--Check the unified meter and A/C amp. Work Flow.
