SHIFT POSITION INDICATOR CIRCUIT

Description
TCM sends 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. Drive vehicle in the manual mode, and confirm that the actual gear position and the meter's indication of the position mutually coincide when the selector lever is shifted to the "UP (+ side)" or "DOWN (- side)" side (1st <=> 5th gear).
Is the inspection result normal?
YES >> INSPECTION END
NO >> Go to, "Diagnosis Procedure". Component Tests and General Diagnostics

Diagnosis Procedure

1. CHECK INPUT SIGNALS

With CONSULT-III
1. Start the engine.
2. Select "GEAR" on "DATA MONITOR" and read out the value.
3. Drive vehicle in the manual mode, and confirm that the actual gear position and the meter's indication of the position mutually coincide when the selector lever is shifted to the "UP (+ side)" or "DOWN (- side)" side (1st <=> 5th gear).
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, "Component Inspection (Manual Mode Switch)". P1815
^ Check A/T main system (Fail-safe function actuated).
- Perform "SELF-DIAG RESULTS" mode for "TRANSMISSION".Refer to, "CONSULT-III Function (TRANSMISSION)".Diagnosis Description With Manufacturer's Scan Tool
NO-2 >> The actual gear position changes, but the shift position indicator is not indicated.
^ Perform "SELF-DIAG RESULTS" mode for "TRANSMISSION".Refer to, "CONSULT-III Function (TRANSMISSION)".Diagnosis Description With Manufacturer's Scan Tool
NO-3 >> The actual gear position and the indication on the shift position indicator do not coincide.
^ Perform "SELF-DIAG RESULTS" mode for "TRANSMISSION".Refer to, "CONSULT-III Function (TRANSMISSION)".Diagnosis Description With Manufacturer's Scan Tool
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. :Refer to, "SHIFT POSITION INDICATOR: System Diagram". Testing and Inspection
