Remove control valve with TCM. Refer to 

TM-240, "Exploded View"

.

2.

Disconnect A/T assembly harness connector and TCM connector.

3.

Check continuity between A/T assembly harness connector and TCM connector.

4.

Check continuity between A/T assembly harness connector and TCM connector.

5.

If OK, check harness for short to ground and short to power.

Is the inspection result normal?

YES

>> Replace the control valve with TCM. Refer to 

TM-240, "Exploded View"

.

NO

>> Replace open circuit or short to ground and short to power in harness or connectors.

SHIFT POSITION INDICATOR CIRCUIT

SHIFT POSITION INDICATOR CIRCUIT

Description

INFOID:0000000000957099

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

INFOID:0000000000957100

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 

TM-170, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000000957101

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 

TM-167, "Component Inspection (Manual Mode Switch)"

.

• Check A/T main system (Fail-safe function actuated). 
- Perform “SELF-DIAG RESULTS” mode for “TRANSMISSION”. Refer to 

TM-114, "CONSULT-III

Function (TRANSMISSION)"

.

NO-2

>>

The actual gear position changes, but the shift position indicator is not indicated.

• Perform “SELF-DIAG RESULTS” mode for “TRANSMISSION”. Refer to 

TM-114, "CONSULT-III

Function (TRANSMISSION)"

.

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 

TM-114, "CONSULT-III

Function (TRANSMISSION)"

.

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 

MWI-20, "SHIFT POSITION INDICATOR : Sys-

tem Diagram"

.

SHIFT LOCK SYSTEM

Description

INFOID:0000000000957102

Shift lock system circuit consists of the following part.

Wiring Diagram —A/T SHIFT LOCK SYSTEM —

INFOID:0000000000957103

Component

Function

Shift lock solenoid

Activated by the ignition switch and stop lamp signals, it holds the relative positions of sliders A and 
B.

Shift lock relay

Current flow to stop lamp switch allows shift lock solenoid contact ON, and then power is applied to 
shift lock solenoid.

Stop lamp switch

Depressing the brake pedal turns ON the stop lamp switch and energizes the shift lock relay.
