SHIFT POSITION INDICATOR CIRCUIT

Description

INFOID:0000000003130560

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

INFOID:0000000003130561

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-91, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000003130562

1.

CHECK INPUT SIGNALS 

 With CONSULT-III

1.

Start the engine.

2.

Select “GEAR” on “Data Monitor” mode for “TRANSMISSION” 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-87, "Component Inspection (Manual Mode Switch)"

.

TM-40, "CONSULT-III

Function (TRANSMISSION)"

.

NO-2

>>

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

• Select “Self Diagnostic Results” mode for “TRANSMISSION”. Refer to 

TM-40, "CONSULT-III

Function (TRANSMISSION)"

.

NO-3

>>

The actual gear position and the indication on the shift position indicator do not coincide.
